[15:51:52] <Aero-Tec> thing are not working like they did
[15:54:12] <Tom_itx> Aero-Tec, it's a freenode thing right now
[15:54:22] <Tom_itx> their servers are all screwed up
[15:54:52] <Aero-Tec> ok
[15:54:54] <Aero-Tec> thanks
[15:55:05] <Tom_itx> give it some time then try
[16:08:56] <DJ9DJ> gn8
[18:11:12] <PetefromTn> Sweet I'll watch for them..
[18:11:15] <JT-Shop> yes I know
[18:11:44] <PetefromTn> whaddya think of that toolpath?
[18:12:38] <PetefromTn> I mean besides the fact that the cuts occur off the material in the picture actually LOL...
[18:13:15] <JT-Shop> I have one free hand can you paste the link again with a space after any text

[18:14:20] <JT-Shop> thanks
[18:14:28] <PetefromTn> yeah man thanks...
[18:14:37] <Tom_itx> freenode is having a ball today
[18:14:47] <JT-Shop> looks good to me
[18:14:56] <PetefromTn> yeah Jt is emailing some balls to me....
[18:15:03] <Connor> What does the CAD look like? Why the rounded edges ?
[18:15:06] <JT-Shop> lol
[18:15:20] <Tom_itx> raise the cutter
[18:15:26] <PetefromTn> is this a serious question..
[18:16:04] <PetefromTn> standby...
[18:16:07] <Connor> Never used sheetcam.. so.. It looks upside down...
[18:16:20] <Connor> or looking at it from the bottom..
[18:16:21] <Tom_itx> is that sheetcam?
[18:16:23] <Tom_itx> can tell
[18:17:28] <Tom_itx> that must be the tool holder holder
[18:17:39] <JT-Shop> what does the backplot in Axis look like?
[18:18:40] <PetefromTn> here ya go....http://s150.photobucket.com/user/matospeter/media/Cincinatti%20Arrow%20500%20Retrofit/cat40fixturescreenshot1_zps1b755584.jpg.html?sort=3&o=0
[18:19:01] <PetefromTn> why does it look upside down?
[18:19:03] <JT-Shop> crap cant click on it
[18:19:11] <Connor> http://s150.photobucket.com/user/matospeter/media/Cincinatti%20Arrow%20500%20Retrofit/cat40fixturescreenshot1_zps1b755584.jpg.html?sort=3&o=0
[18:19:14] <PetefromTn> yeah sheetcam...
[18:20:30] <JT-Shop> seems to be missing the outside
[18:21:19] <Connor> okay, so, your just making it look rounded on the outside edge instead of being straight..
[18:21:43] <Connor> looks upside down, or looks like looking from bottom because the angle of the CAM drawing.
[18:21:47] <PetefromTn> Ya know the only thing I don't like about sheetcam is that whenever you program a pocket or profile with multiple passes it has to finish the pass and then go to safe Z and then lower back down into the depth of the next layer instead of just dropping down into the next depth...
[18:22:09] <JT-Shop> you might twiddle with the post
[18:22:29] <Tom_itx> does somebody have a good post for it for linuxcnc?
[18:22:39] <JT-Shop> mine is for plasma
[18:22:39] <Tom_itx> or is it integrated
[18:22:43] <Connor> Right now, I can't CAD or CAM because my windows VM is having issues.. :(
[18:22:54] <JT-Shop> they have an EMC post
[18:23:07] <PetefromTn> that would be a bitch for each time it drops down... Art says it is because sheetcam does not know if there are obstructions in the way when it cuts...
[18:23:17] <PetefromTn> Yeah there is an EMC post that seems to work just fine..
[18:23:17] <Tom_itx> is sheetcam free?
[18:23:29] <PetefromTn> No it is like $200.00 US or something like that.
[18:24:02] <PetefromTn> I actually quite like it tho... and now it has V-carving as well as rigid tapping and peck drilling etc...
[18:24:16] <Tom_itx> can you edit the tool path once it's generated?
[18:24:19] <PetefromTn> only wish it would do some 3d stuff I would be happy...
[18:24:39] <PetefromTn> sure and you can just run the PP again too..
[18:24:41] <Tom_itx> like what?
[18:25:06] <PetefromTn> just click on each operation in the bottom left and it brings up dialog box with the settings... simple..
[18:25:19] <Tom_itx> i don't have it
[18:25:28] <PetefromTn> don't have what?
[18:25:32] <Tom_itx> sheetcam
[18:25:45] <JT-Shop> 95% of the stuff I do is really 2 1/2D, profiles, pockets, holes and tapping
[18:25:48] <PetefromTn> you can download a free trial if you think you want to..
[18:26:03] <PetefromTn> yeah me too... but I want to do more 3d stuff...
[18:26:17] <PetefromTn> Looking at the Deskproto this morning looks pretty powerful.
[18:26:40] <PetefromTn> Sheetcam is actually excellent for that stuff just no 3d..
[18:26:42] <JT-Shop> andypugh: is doing some 3-D stuff with ... I forget
[18:27:00] <PetefromTn> huh?
[18:28:23] <Tom_itx> oh pycam
[18:28:32] <Tom_itx> but he wasn't real excited with it
[18:29:19] <PetefromTn> pycam actually looks quite nice but he said the processing seemed slow..
[18:30:02] <PetefromTn> CAmBam actually has some decent 3d functionality...
[18:30:50] <PetefromTn> had I known that CamBam was gonna have 3D I would have gone with it instead of Sheetcam but my pal art knows Sheetcam real well so I had a lot of help with it. Worth a lot to me...
[18:32:07] <JT-Shop> having help over the big learning hurdle can be worth a lot
[18:32:51] <JT-Shop> now that I have both hands back lol, if you put a space between text and a link it is clickable
[18:32:56] <Tom_itx> oh, free is 180 code lines
[18:33:20] <PetefromTn> yeah especially if you're me...
[18:33:25] <Tom_itx> wonder how efficient code they spit out :)
[18:34:17] <PetefromTn> everything I have made on my CNC's has been with sheetcam...
[18:44:58] <PetefromTn> Connor: Hey man you got CamBam?
[18:45:32] <Connor> I Just had the eval version.. Going to have to re-download it.. my windows VM crashed.. re-doing it now..
[18:46:22] <PetefromTn> VM?
[18:46:41] <Connor> Virtual Machine
[18:46:56] <Connor> I run Linux as my desktop.. and VMWare so I can run windows and other OS's
[18:47:50] <Tom_itx> how do you get an iso view?
[18:47:59] <PetefromTn> Can you tell me if you program a pocket say that is 2" diameter, and .5" deep in .050 deep passes will it retract to the safe plane after each successive depth or will it just drop down into the next lower depth?
[18:48:26] <PetefromTn> You can either select it or do like I do and press SHIFT and click and drag the mouse...
[18:48:28] <Connor> It will just drop down.. you can also set it up so that it ramps down
[18:48:59] <PetefromTn> Are you sure, I mean sheetcam can ramp down into the cut initially but subsequent ones I am not sure of...
[18:49:08] <Connor> Say, you want a .010 DOC.. you can tell it to do that in a full 360 degree path.. so, when it's back at the start point.. it'll be at .010 DOC
[18:49:23] <Tom_itx> PetefromTn, can you connect a line between the layered holes?
[18:49:35] <Tom_itx> that will make it one continuous profile
[18:49:43] <Connor> You can do a single ramp, or a spiral ..
[18:50:21] <PetefromTn> Sure but what happens when the machine has to do the next pass in a successive pocket operation down in depth?
[18:50:44] <Connor> It retracts the tool.
[18:50:52] <Connor> to specified safe height..
[18:50:54] <PetefromTn> Tom_itx: Not sure what you are asking me man...
[18:51:07] <PetefromTn> So it does the same thing as Sheetcam does...
[18:51:08] <Tom_itx> yeah mine will retract to the safe z unless i edit it
[18:51:19] <Connor> Each operation the tool is retracted..
[18:51:33] <Tom_itx> i can tell it where safe z is for each pass though
[18:52:08] <PetefromTn> No what I am asking you is in a SINGLE operation where the pocket is programmed for successive depth passes does it return to safe Z before starting the next plunge?
[18:52:25] <Connor> NO.
[18:52:34] <jdh__> that would seem silly
[18:52:38] <PetefromTn> Tom_itx: What are you using?
[18:52:45] <Tom_itx> smartcam
[18:52:50] <PetefromTn> jdh__: Agreed it is silly...
[18:53:02] <PetefromTn> never heard of smartcam..
[18:53:09] <Connor> It Will just drop down and do the next pass.
[18:53:11] <Tom_itx> i generally don't use the canned pocket rouines on mine
[18:53:13] <PetefromTn> is it?
[18:53:32] <PetefromTn> Are you sure?
[18:53:51] <Connor> Me?
[18:54:02] <Tom_itx> http://www.smartcamcnc.com/
[18:54:07] <PetefromTn> Do this for me if you can, draw a simple 2" circle, machine it with .050 DOC passes down to .5" deep and post the code...
[18:54:29] <jdh__> with a 1" end mill
[18:54:31] <Connor> PetefromTn: Who you talking to? Me or Tom? I'm confussed..
[18:54:39] <Tom_itx> PetefromTn, who?
[18:54:55] <PetefromTn> Connor: you....using a 3/8 endmill for instance..
[18:55:13] <Connor> Okay. Give me just a bit.. I have to re-download CamBam on my machine.
[18:55:15] <PetefromTn> hell both of you it will be interesting to see he differences...
[18:55:21] <Tom_itx> that's a rather shallow cut
[18:55:27] <PetefromTn> Sure is...
[18:55:31] <PetefromTn> Just a for instance..
[18:56:13] <PetefromTn> I am trying to figure out if other cam programs I can afford will NOT do the only thing that Sheetcam does that is annoying to me.
[18:56:48] <Connor> Downloading CamBam now.
[18:57:17] <PetefromTn> I cannot understand why after each successive pass the cutter must go to safe Z and then slowly lower at plunge feedrate back to the next depth...
[18:57:27] <jdh__> what does that?
[18:57:38] <PetefromTn> does what?
[18:57:42] <Connor> okay, Spiral or just normal profile ?
[18:57:47] <Connor> and Pocket or Profile ?
[18:57:48] <jdh__> what cam does what you just decribed?
[18:57:56] <PetefromTn> Sheetcam...
[18:58:09] <PetefromTn> Sheetcam has both.. does not seem to matter.
[18:58:54] <PetefromTn> Sheetcam has Spiral Pocket,zigzag pocket,and face pocket routines...
[18:59:25] <jdh__> Pete: http://pastebin.com/zqPKBq97
[19:00:16] <PetefromTn> I am sure there is some good reason for it but I cannot imagine what that would be...
[19:00:23] <PetefromTn> jdh__: what cam is that?
[19:00:41] <jdh__> cut2d
[19:01:27] <Tom_itx> -kloeri- [Global Notice] Hi all, apologies for the continued netsplits. We're having some issues stemming from a DDoS attack but we're working with our sponsors on attack mitigation. Thank you for using freenode.
[19:01:36] <PetefromTn> looks like cut2d does not do this..
[19:02:00] <Connor> PetefromTn: You want it to pocket, or Profile this circle ?
[19:02:03] <PetefromTn> Maybe I am just not doing it right.....but I cannot imagine what I am doing wrong to cause this..
[19:02:11] <PetefromTn> inside pocket...
[19:02:25] <Connor> okay..
[19:03:45] <Connor> Conventional or Climb ?
[19:03:50] <PetefromTn> actually looking again at the cut2d file it seems like it does go to safe Z after each pass... don't have a simulator handy.
[19:03:55] <PetefromTn> should not matter...
[19:04:41] <PetefromTn> jdh__: do you see that?
[19:06:12] <PetefromTn> Maybe as I said there is a good reason for this...
[19:07:16] <PetefromTn> I need to download CamBam and play with it I think...
[19:07:24] <Connor> http://pastebin.com/JBytf0N4
[19:08:40] <PetefromTn> well looks like cambam does it too...
[19:09:01] <PetefromTn> It goes up to Z.125 then goes down to the next Z depth in a plunge...
[19:09:02] <Connor> let me run it in my simulator..
[19:09:17] <Connor> On a POCKET, yes.
[19:09:25] <PetefromTn> You say it has the ability to ramp in on each successive pass tho?
[19:09:26] <Connor> On a Profile, No.
[19:09:35] <Connor> On profiles.
[19:09:48] <PetefromTn> Sheetcam does it on either one..
[19:09:58] <Connor> Let me do a profile..
[19:10:02] <robh__> wire a sub and call it to ramp or spiral in ;) as im sure each plunge is the same place also
[19:10:15] <PetefromTn> Does it not seem like it should be able to just drop down after each pass and continue without that silly up movement?
[19:10:52] <PetefromTn> robh__: actually that is one of the nice things about sheetcam is you can code about anything you want in it.
[19:11:08] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/test/
[19:11:11] <Connor> PetefromTn: I would run the cutter accross the bottom of the floor of the pocket..
[19:11:21] <Tom_itx> haven't looked at it
[19:11:28] <Tom_itx> just generated a helix
[19:11:36] <robh__> sure i dont know as Solidworks user with camworks you see
[19:12:01] <PetefromTn> Art said it is because if you have an irregularly shaped pocket that has protrusions and it starts at the wrong point it would crash into the protrusion as it traverses to the next start point...
[19:13:03] <PetefromTn> Tom_itx: that is not the same thing because that is a spiral plunge kind of cut. It would probably only do that in a circular pocket which I know is what I asked about LOL
[19:13:22] <Tom_itx> what do you want?
[19:13:23] <PetefromTn> robh__: What would solidworks with camworks do in this instance?
[19:13:51] <robh__> not sure what your trying to do i read a small part of it throught u was trying to get a ramp in on pocket start but maybe not
[19:14:00] <robh__> trying to hold down in a pocket, not move to a Z clear hight?
[19:14:12] <Connor> PetefromTn: Okay. On the pocket... it moves the tool up to "safe" height.. which I can specify. I tend to only make it .125" above the work.. (this is for pockets)
[19:14:16] <PetefromTn> Just a simple pocket with successive depths of .050 in a 2" pocket .5 deep...
[19:15:02] <robh__> well normaly it moves to the safe hight part which is what ever you define normal say 2mm above part stock... unless you ask for hold down or tell it clearence is last cut depth
[19:15:19] <PetefromTn> robh__: yeah the move to safe Z height is a waste of time cutting air and is in every single pocket or profile cut I do..
[19:15:44] <PetefromTn> robh__: Clearance is last cut depth sounds yummy...
[19:16:00] <robh__> but you need to watch for any islands etc...like any cam but u just move the start point if you can
[19:16:38] <robh__> or you turn on Volume Mill and realy move some metal :)
[19:16:40] <PetefromTn> Connor: yeah that is what I do too... but the wasted air is annoying.
[19:17:00] <Connor> http://pastebin.com/SDgtMjAB
[19:17:06] <Connor> 2" circle inside profile..
[19:17:09] <Connor> No wasted air.
[19:17:13] <PetefromTn> robh__: okay...
[19:17:43] <robh__> id say it does not take that much time to rapid to clear and back in.. unless have a realy slow machine
[19:17:53] <PetefromTn> Connor: Okay man now we are getting somewhere...
[19:18:14] <robh__> unless your cam is doing a lot of lifts and back in on a pocket for some odd reason on the same depth
[19:19:08] <PetefromTn> well yeah actually it DOES take a lot of time if it does it at EACH AND EVERY DEPTH!!
[19:19:17] <Connor> http://pastebin.com/weA1vvmp
[19:19:34] <Connor> 2" profile with Spiral lead in..
[19:19:57] <Connor> Which is what I prefer to use.
[19:19:59] <PetefromTn> damn that looks better...
[19:20:13] <PetefromTn> That is an inside profile..
[19:20:27] <Connor> Yea. Same can be done on out side..
[19:20:52] <PetefromTn> but it does not work on a pocketing op...
[19:21:02] <Connor> Let me check something.
[19:21:05] <Tom_itx> here's another one...
[19:21:20] <PetefromTn> This is interesting isn't it...
[19:21:36] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/test/pocket.ngc
[19:21:56] <Tom_itx> i programmed the tool center
[19:22:01] <Tom_itx> so it will be over 2"
[19:22:09] <Tom_itx> err did i?
[19:22:11] <Tom_itx> mmm
[19:22:44] <Tom_itx> no it should be ok
[19:23:02] <PetefromTn> Tom_itx: Looks like it comes out of the cut on yours too in a pocketing op.
[19:23:56] <Connor> PetefromTn: I don't think it's going to do it on a pocket.. I think it will always retract..
[19:24:27] <PetefromTn> I suppose I can see the reasoning behind it, if you look at the part I am working on, if the cut starts somwhere in the circle and ends in the longish parts and then moves to the start again it will rip off the corner of the straight portion...
[19:24:30] <robh__> sometimes you cant beat a bit of code edit
[19:25:12] <PetefromTn> Honestly if CamBam does this on a pocket but not a profile and has 3d toolpathing it is worth a second look that is for sure...
[19:25:29] <PetefromTn> robh__: Yeah but editing every pocket you draw would be a real pain in the ass..
[19:25:34] <Tom_itx> it shouldn't
[19:25:53] <PetefromTn> what should'nt
[19:26:21] <Tom_itx> oh it may go to z safe
[19:26:33] <PetefromTn> that's what I am talking about..
[19:26:44] <PetefromTn> its annoying waste of time.
[19:26:44] <Tom_itx> i can tell it what to do though i think
[19:26:54] <PetefromTn> show me...LOL
[19:26:55] <Tom_itx> i just posted a quick pocket
[19:27:11] <Tom_itx> you don't have smartcam
[19:27:24] <PetefromTn> show me the posted code LOL
[19:27:38] <Tom_itx> it's in the link i posted
[19:27:45] <PetefromTn> How much is Smartcam?
[19:27:52] <Tom_itx> 8k +
[19:28:03] <PetefromTn> The link you posted the cutter comes out of the hole to safe Z
[19:28:14] <PetefromTn> Nevermind LOL...
[19:29:48] <Tom_itx> PetefromTn, did you get the pocket one?
[19:30:24] <PetefromTn> Got two both do the same thing..
[19:30:39] <Tom_itx> feed & speed are way off too
[19:30:43] <Tom_itx> didn't bother
[19:31:27] <Tom_itx> they do different things
[19:31:47] <Tom_itx> one cuts the pocket from the center out and the other cuts a spiral
[19:32:41] <PetefromTn> yeah but it still goes to safe z after each depth right?
[19:32:47] <robh__> PetefromTn, dont forget you dont wanna drag that cuutter over a surface ull end up with marks if finish level or chiping the flutes too
[19:32:59] <PetefromTn> Honestly does not matter because I am not gonna buy an 8k program
[19:33:16] <robh__> http://pastebin.com/Z2867vNz
[19:33:27] <Tom_itx> if you want full blown 3d you might
[19:34:08] <PetefromTn> robh__: yeah that would be true if you did not intend to cut that level off on the next pass tho..
[19:34:37] <robh__> i did a quick one lifts are over to the next spiral in hight inside the pocket
[19:35:07] <Tom_itx> even so, if you rapid to the start of the next pass you're gonna drag the cutter
[19:35:30] <Tom_itx> unless you raise it to the z clear
[19:35:47] <Tom_itx> i can make z clear be .0001 if i want
[19:36:04] <PetefromTn> So can I but it is annoying..
[19:36:11] <PetefromTn> Maybe I am just a whiner LOL
[19:36:14] <Tom_itx> you are
[19:36:15] <robh__> indeed like even things like volumemill dont like u setting high speed feed links to zero
[19:36:20] <Tom_itx> it's the way it should be done
[19:37:24] <PetefromTn> I guess what I was wanting was the cutter to do the circular pocket spiraling outward, then when it reaches the end of the layers cut maybe ramp down from there and do it again but perhaps that is not possible.
[19:37:51] <Tom_itx> you'd have to reverse the cutter path each level
[19:38:01] <PetefromTn> okay sounds good...
[19:38:36] <PetefromTn> Honestly just the fact that CamBam can do this on profile is a big deal since I use a lot of profiles in my stuff...
[19:39:03] <PetefromTn> Not cracking on sheetcam here as I honestly quite like it but that is a real time saver that much is clear.
[19:39:25] <PetefromTn> Even with a faster machine that rapids at 600+ IPM like my machine that is a PIA...
[19:39:48] <robh__> depends how fast accel is too
[19:40:09] <PetefromTn> Sure does...honestly that is actually even more important most of the time..
[19:41:02] <robh__> mind u, i have seen shops with 50m/min machines but only run them at 50% speed lol becasue it scares them
[19:41:02] <PetefromTn> it takes a moment or so to reach full speed no matter what your machine is so accel rates from hole to hole nearby are even more of a factor on speed..
[19:41:29] <PetefromTn> robh__: I know mine scares me but I am just getting started using it.
[19:41:44] <robh__> yea, i know that feeling
[19:42:07] <PetefromTn> yup accel is considerably more a factor on cycle time than speed.
[19:42:08] <robh__> what are your rapids, 12m? or more
[19:42:25] <robh__> or should i convert to inch mode now
[19:42:59] <PetefromTn> Just screwing around with it as I just got it working but I can see 650 or so IPM on X and Y and 500+ on Z but it is a pucker....
[19:43:12] <PetefromTn> especially in only 20 inches in all directions.
[19:43:26] <robh__> that is nice
[19:43:49] <robh__> sometimes its what the screws will take in speed, if supported both ends they will take it nice
[19:43:51] <PetefromTn> yeah man I doubt I will actually be using it too much..
[19:44:19] <PetefromTn> right now 300 feels about right and 200 on the Z I can stand..
[19:44:39] <PetefromTn> If I got some paying repeat jobs that were run a lot I am sure I would ramp it up...
[19:45:00] <PetefromTn> Nice to know it is there tho ;P
[19:45:25] <robh__> lo, then you will wish u had a faster atc
[19:45:42] <robh__> did you get it tool changing yet?
[19:46:11] <PetefromTn> hell no I still need to machine a Spindle motor encoder mount and get feedback working.
[19:46:35] <robh__> aah i see
[19:47:18] <PetefromTn> I do have the tool carousel ram wired up as well as the power drawbar and some sensors..
[19:47:40] <PetefromTn> Almost afraid to tackle the toolchanger really...
[19:47:41] <ssi_> JT-Shop: around? I have thcud questions
[19:48:01] <robh__> you mean try not part the tool changer off with the Z
[19:48:17] <PetefromTn> Yes that is EXACTLY what I mean.
[19:48:54] <PetefromTn> Oh well enough BS'ing here. Gonna go do something.
[19:49:01] <PetefromTn> have a good night fellas.
[19:49:10] <robh__> cya
[20:06:26] <Connor> What does better for inside profile finish? Climb or Conventional ?
[20:08:03] <Tom_itx> i prefer climb but it depends on the machine rigidity
[20:08:32] <Connor> I know that one way gives a much smoother finish.. I just never can remember which way..
[20:10:57] <Tom_itx> http://www.cnccookbook.com/CCCNCMillFeedsSpeedsClimbConventional.htm
[20:11:00] <Connor> okay, on my U-Shapped Profile.. it's going back and forth...
[20:19:26] <Connor> Whats a good RPM / IPM for a 3/8" cutter doing 6051 Alumn ?
[20:20:25] <Tom_itx> http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[20:20:37] <Tom_itx> http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[20:21:36] <LokiScarlet> Yo. Annoying newbie is back. o/
[20:25:32] <Connor> Wow... 5300 RPM @ 50 IPM ?
[20:25:51] <Connor> That scares the sh!t out of me..
[20:26:05] <Tom_itx> are you running carbide?
[20:26:14] <Connor> no, Thats the a HSS bit.
[20:26:28] <Tom_itx> what's your max rpm?
[20:27:00] <Connor> 6061 Alum, Solid End Mill with HSS, Tool Dia .375, Length .75, I set the DOC at 0.05, Max RPM is 6500
[20:27:10] <Cylly> Connor: mostly the cutting speed for carbide is scaring. and mostly the hobby machines arent anywhere rigid enough to do them
[20:27:18] * LokiScarlet <that info> ------- <about 9000 meters altitude difference> ---- <my head>
[20:27:39] <Connor> http://zero-divide.net/index.php?page=fswizard&shell_id=199&load_tool_id=27011
[20:27:44] <Connor> based on that.
[20:28:08] <Tom_itx> you also need to consider what your machine will do
[20:28:17] <LokiScarlet> So uh... What's IPM? Since I'm still trying to get my laptop to work right and I'm on a tablet -_-
[20:28:29] <Tom_itx> with carbide you can cut aluminum like butter
[20:28:40] <Cylly> thats whar i meant
[20:28:41] <Cylly> ;-)
[20:29:02] <Connor> I don't have Carbide.. just HSS bits.
[20:29:13] <r00t4rd3d> http://i.imgur.com/gSzOsIn.jpg
[20:29:20] <Tom_itx> get some carbide
[20:29:31] <Connor> Planning on doing this tonight.
[20:29:38] <Tom_itx> just a sec
[20:30:02] <Connor> I mean.. I know I can cut this.. I've done it before.. but a few things has changed.. like my max RPM went from 3k to 6.5k
[20:31:17] <Cylly> i am cutting 7075 with a 2 flute carbide endmill 6mm at 15kRPM and F2400 ;-)
[20:32:29] <LokiScarlet> >finally found IPM; >inches per minute; o_O okay now I understand what you're talking about
[20:33:12] <Tom_itx> Connor, try around 5000 rpm 10 ipm
[20:33:15] <Tom_itx> see what happens
[20:33:30] <Connor> That'll weld chips to the cutter...
[20:33:46] <Connor> I've read about running too low of IPM will cause chip welding.
[20:33:48] <gammax-Laptop1> hola hombres
[20:33:55] <Tom_itx> that's .002" chip load
[20:34:10] <Tom_itx> increase it to .004 then
[20:34:29] <Tom_itx> oh wait. i was reading the plunge feed
[20:34:35] <Tom_itx> 20 ipm
[20:34:45] <Tom_itx> .004 chip load would be 40
[20:34:59] <Connor> So what's 50 IPM at 5300rpm ?
[20:35:02] <gammax-Laptop1> if you guys had a piece of steal that needed to be 1"x1.5" would you buy the same size stock or up the size a bit?
[20:35:14] <Tom_itx> .005
[20:35:28] <Tom_itx> .0047
[20:35:39] <Connor> What are you using to get those #'s ?
[20:35:46] <Tom_itx> my cad cam
[20:35:59] <Tom_itx> any chip calc will give it
[20:36:05] <Tom_itx> the one i linked should
[20:36:17] <Connor> Is that IPT ?
[20:36:32] <Tom_itx> yes
[20:36:39] <LokiScarlet> gammax-Laptop1: I dunno about you but I'd get slightly larger. But that's probably just me. I don't even have experience with cutting
[20:36:40] <Tom_itx> 2 flute
[20:36:45] <Tom_itx> .0047 ipt
[20:36:49] <Connor> Right. That's what I use for ALumn.
[20:36:54] <Tom_itx> 5300 rpm
[20:37:06] <Tom_itx> 520 sfm
[20:37:15] <Tom_itx> 50 ipm
[20:37:54] <Connor> I'm pretty sure my machine can handle the IPM and RPM.. just not sure if it's "rigid" enough to handle it..
[20:38:01] <gammax-Laptop1> LokiScarlet, If you bought a bar of 1045 steel... would it look premachine already or just look nasty?
[20:38:04] <ssi_> gammax-Laptop1: depends on the finish you need
[20:38:05] <Connor> Says Cutting force is 39.31lb
[20:38:14] <ssi_> gammax-Laptop1: no, mostly doesn't look premachined
[20:38:16] <Connor> That's at .1 DOC
[20:38:19] <Tom_itx> Connor, one way to find out
[20:38:39] <gammax-Laptop1> ssi_, would taking a thousandth off dothe trick on each side?
[20:38:54] <ssi> as long as it's less than a thousandth surface variation! :D
[20:39:06] <ssi> I'd plan to take at least ten mil off every face
[20:39:08] <Connor> I decrease the DOC to .05"
[20:39:09] <gammax-Laptop1> how often does that happen
[20:39:14] <LokiScarlet> Yeah if you want a good machined finish you'll want some padding in your size
[20:39:54] <gammax-Laptop1> im thinkin about buying some cheap fly cutters vs face mills...
[20:40:01] <toastyde2th> bar product should be .1" over on all dimensions if it's fresh from the steel mill
[20:40:10] <ssi> gammax-Laptop1: fly cutter is a very good way to go
[20:40:18] <ssi> I use them to great effect, and they're much cheaper than face mills
[20:40:20] <Tom_itx> Connor, also depends on your depth and width of cut
[20:40:25] <LokiScarlet> Rule of thumb for network administration, probably applies here too: Never trust stock condition
[20:40:41] <Connor> profile, 100% engagement 90% of the time.
[20:40:54] <toastyde2th> as you cut cold rolled steel, it's going to bend, so if you want a part that's flat you're going to have to cut all sides twice
[20:41:14] <gammax-Laptop1> ssi, you use shars or a quality one?
[20:41:46] <Tom_itx> Connor, how deep?
[20:42:05] <Connor> Material is .5" thick. planning on .05" DOC
[20:43:00] <ssi> gammax-Laptop1: shars is fine
[20:43:18] <gammax-Laptop1> oh btw I picked up those keneddy boxes today. for an extra 50 bucks I got machinerys hand book, spindle indicator holder, 2 locators, uhhh and an brown and sharp indicator with extra long tips in wooden box.
[20:46:27] <Tom_itx> gammax-Laptop1 another handy book is the Machinists' Ready Reference
[20:46:32] <Tom_itx> little spiral book
[20:49:59] <gammax-Laptop1> hmmm gotta find a cheap one im broke@
[20:50:02] <gammax-Laptop1> !
[20:51:30] <Tom_itx> holy crap the price on that went up
[20:51:37] <Connor> ??
[20:52:47] <Tom_itx> http://www.amazon.com/Machinists-Ready-Reference-6th-Edition/dp/0911168508/ref=sr_1_1?ie=UTF8&qid=1368322635&sr=8-1&keywords=Machinists%27+Ready+Reference
[20:53:08] <Tom_itx> oh, mine _is_ spiral
[20:53:11] <Connor> Wow, Paper Back vs is $$$$
[20:53:19] <Connor> the Spiral is cheaper.
[20:53:22] <Tom_itx> gotta be a misprint
[20:53:31] <ssi> more like an out of print
[20:53:39] <Tom_itx> or that
[20:53:40] <ssi> amazon does weird stuff with out of print things
[20:53:41] <r00t4rd3d> lol
[20:53:49] <Tom_itx> i haven't seen anything but spiral bound
[20:54:49] <Tom_itx> http://www.amazon.com/Machinists-Ready-Reference-C-Weingartner/dp/0970339801/ref=sr_1_1?s=books&ie=UTF8&qid=1368322824&sr=1-1&keywords=Machinists%27+Ready+Reference+8th+edition
[20:54:53] <Tom_itx> 9th edition
[20:54:57] <Tom_itx> i've got the 8th
[20:54:59] <ssi> I think this machine might be too big for me
[20:55:02] <ssi> http://atlanta.craigslist.org/atl/for/3661772392.html
[20:55:34] <r00t4rd3d> http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=Machinists%27+Ready+Reference&rt=nc&LH_BIN=1
[20:55:41] <Tom_itx> never too big
[20:55:46] <ssi> it's 50klb
[20:55:47] <ssi> :(
[20:55:50] <Tom_itx> our okuma had a changer like that
[20:55:56] <Tom_itx> 99 tool iirc
[20:56:02] <ssi> although if I gtot that
[20:56:08] <ssi> I could get all andy's BT50 tooling he doesn't want
[20:56:09] <ssi> lololol
[20:56:28] <Tom_itx> that one's a 40 taper
[20:56:34] <jdh__> 22kW
[20:56:41] <ssi> oh it's contradictory
[20:56:50] <ssi> says cat40 spindle in the top, bt50 in the bottom
[20:56:53] <ssi> ATC:
[20:56:53] <ssi> Tool Shank System: MAS BT50
[20:56:54] <ssi> Pull-Stud Bolt Type: MAS Type 2
[20:56:55] <Tom_itx> we had a 50 taper
[20:57:52] <toastyde2th> 50 taper is so heavy
[20:57:57] <toastyde2th> loading 30 tools into machine is a pain
[20:58:05] <toastyde2th> * a machine
[20:58:05] <ssi> max table capacity, 3520lb
[20:58:07] <ssi> a small car
[20:58:08] <ssi> haha
[21:00:26] <Connor> I Do love being able to run my gcode on my simulator before running on the machine.
[21:00:31] <ssi> so now that the plasma table is basically done, I need to work on the g0704
[21:04:52] <Connor> okay, RPM and Plunge IPM for .25" and .323" holes using pecking?
[21:05:43] <Tom_itx> i shut it down
[21:07:39] <Valen> I was thinking, a neat addition, hook up a kinect to the head of the mill, before running the program, scan the work area and check you arent going to try and rapid through your vice
[21:18:18] <Tom_itx> Connor, figure around .008 ipt
[21:22:24] <Tom_itx> 4000 r 32 f
[21:33:40] <Connor> for both? or just the .25"
[21:39:32] <Tom_itx> i figured the .25
[21:39:41] <Tom_itx> you could start with .006 chip load
[21:44:34] <ssi> how fast do you suppose you can spin a ballscrew?
[21:44:52] <Tom_itx> depends on the diameter before it will whip
[21:45:12] <ssi> so the most whip prone one in my application is about 30" long and 5/8"
[21:45:22] <ssi> wondering if I can direct couple these servos or if I'll have to reduce them
[21:45:31] <ssi> I think they're 5300rpm motors nominally
[21:45:32] <ssi> seems fast
[21:45:54] <ssi> .200" lead screws, that'd be ~1000ipm at max speed
[21:45:55] <Tom_itx> probably a bit much, what's the pitch on them?
[21:46:04] <ssi> probably too fast for a g0704 haah
[21:46:55] <Tom_itx> no reason to cause premature wear
[21:47:12] <ssi> I may built it direct coupled and just not run it that fast
[21:47:18] <ssi> adn then use it to make some belt reductions for itself
[21:47:32] <generic_nick|3> i am tired
[21:47:45] <generic_nick|3> cleaning the shop and sanding the floor all damn day
[21:47:52] <ssi> 5:1 reduction would put it pretty close to where I want
[21:47:53] <jdh__> i have 2:1 belt on my g0704 Z, but the other way around.
[21:48:07] <ssi> jdh__: the other way around? you're speeding up your Z travel?
[21:48:23] <ssi> seems like you'd want a reduction on Z as well
[21:48:25] <jdh__> oh, no I was thinking of it backwards
[21:48:32] <ssi> more torque, less speed
[21:48:35] <jdh__> yeah
[21:49:04] <ssi> if I do 5:1 reduction, I'll get about 200ipm travel on each axis
[21:49:05] <jdh__> I don't need the speed
[21:49:10] <ssi> and five times the motor torque
[21:49:26] <ssi> but the belt reductions will be bulky as crap
[21:49:41] <jdh__> I can get 180 ipm out of the steppers for x/y, but I dont' have them that fast.
[21:49:50] <ssi> yeah that's quick for that machine
[21:50:00] <jdh__> Z belt goes behind the column. You can do that for Y also.
[21:50:17] <ssi> is your Y motor on the backside of the column?
[21:50:20] <ssi> cause mine's in the front for now
[21:50:41] <jdh__> mine is on the front, you can drill through the column and mount it on the back though
[21:50:46] <ssi> yeah I thought about it
[21:50:56] <ssi> I might do that
[21:51:02] <ssi> then I can just plasma cut a plate to mount the motor on
[21:51:08] <ssi> and it can be the belt reduction
[21:51:26] <jdh__> I used the mill to make the mounts
[21:51:38] <ssi> mine's torn down irreparably :)
[21:51:42] <ssi> but I have a 9x42 manual
[21:54:57] <ssi> I need to make ballnut mounts
[21:55:03] <ssi> which involves getting a lathe functional :P
[21:55:52] <jdh__> I made mine on the mill
[21:55:59] <generic_nick|3> what came first, the chicken or the lathe
[21:56:08] <ssi> how do you thread them?
[21:57:10] <jdh__> the ballnuts are flange mount
[21:57:52] <ssi> mine aren't
[22:03:20] <Tom_itx> get a thread mill
[22:05:42] <jdh__> can you do threadmilling on a manual mill?
[22:06:32] <Tom_itx> would be hard
[22:07:19] <Tom_itx> http://www.iscar.com/Ecat/familyHDR.asp?fnum=2828&app=120&mapp=TH&GFSTYP=M&type=1&lang=
[22:07:37] <toastyde2th> you'd need a REALLY good rotary table
[22:07:42] <toastyde2th> and a horizontal mill
[22:08:01] <toastyde2th> good rotabs can be keyed to the table screw and geared so they turn at a specific rate
[22:08:34] <jdh__> then it's not really a manual mill
[22:08:47] <toastyde2th> sure it is
[22:09:24] <jdh__> or, you could get a tap that fit the nut
[22:10:56] <Tom_itx> on those single point mill thread cutters, do you cut it in a single or multiple passes?
[22:11:17] <Tom_itx> lathe single point we did multi pass
[22:11:34] <Tom_itx> never tried that on a mill yet
[22:12:02] <Tom_itx> you would basically just program a helical cut right?
[22:12:28] <toastyde2th> yep
[22:12:33] <Tom_itx> probably from the bottom out?
[22:12:37] <toastyde2th> yep
[22:13:00] <toastyde2th> the better threadmills have a long ass cutting face so you really only need to go up one thread
[22:13:10] <Tom_itx> i guess you wouldn't have to have a synch'd spindle for that
[22:13:16] <toastyde2th> not a big fan of the single pointers
[22:13:26] <Tom_itx> like the one i linked...
[22:13:29] <toastyde2th> nope, no spindle synch
[22:13:43] <Tom_itx> looks like 4 point
[22:15:25] <Tom_itx> i wanna try that sometime
[22:15:40] <Tom_itx> those cutters aren't cheap though
[22:15:53] <toastyde2th> yeah
[22:20:19] <ssi> I don't want to get the tap, because I have two different sized ballnuts
[22:20:22] <ssi> and the small tap is $70
[22:20:29] <ssi> I can thread it on the lathe
[22:20:35] <ssi> one of em :P
[22:20:42] <Tom_itx> single point thread mills are $150 +
[22:21:33] <ssi> hell I can do it on the manual lathe if I have to
[22:21:49] <Tom_itx> toastyde2th, i can't picture how those work without having spindle synch
[22:22:08] <toastyde2th> so you turn the spindle on and drop the cutter to your max depth
[22:22:21] <toastyde2th> then move the cutter out to the final diameter
[22:22:44] <Tom_itx> i know the profile it just seems it would 'strip' the threads unless it was in sync
[22:22:45] <toastyde2th> and then do a full circular helical move with the center point in the middle of the hole
[22:22:52] <toastyde2th> how would it strip the threads
[22:23:04] <Tom_itx> the cutters i'm looking at are multi point
[22:23:05] <toastyde2th> you're profile milling
[22:23:16] <toastyde2th> it's not like a tap, it's like a regular endmill except it's gone a shape on the outside
[22:23:28] <toastyde2th> how would spindle synch work at all
[22:23:40] <ssi> think about it like this
[22:23:43] <Tom_itx> dunno, i just can't picture it in my head
[22:23:48] <Tom_itx> i'm sure it works :)
[22:23:48] <ssi> if your helical move is too slow
[22:23:59] <ssi> say, 0
[22:24:04] <ssi> if you just made a cut in a circle
[22:24:09] <ssi> it'd cut a wavy pattern in the metal that's not a thread
[22:24:39] <Connor> Tom_itx: what about the .323" drill ?
[22:24:46] <ssi> the Z component of the helical move has to be sync'd to the spindle speed and the pitch or else it'll just bore the hole clean
[22:24:47] <Tom_itx> so the points don't have pitch like a screw
[22:24:53] <Tom_itx> they're more straight
[22:25:07] <ssi> it's no different than using a full profile threading insert on a lathe
[22:25:11] <ssi> you still need spindle sync
[22:25:59] <toastyde2th> what
[22:26:14] <toastyde2th> all you need is to be able to move the z and xy at the same time
[22:26:22] <toastyde2th> the spindle just has to be on at some speed, any speed
[22:26:26] <toastyde2th> i've used both types many times
[22:26:28] <ssi> so what if the speed is 24krpm
[22:26:50] <toastyde2th> you wind up with a thread
[22:26:52] <ssi> for every revolution of the points of the mill, a full circle of metal is removed
[22:26:56] <toastyde2th> no, it isn't
[22:27:01] <ssi> why not
[22:27:13] <toastyde2th> because that's not how the tool is used
[22:27:14] <toastyde2th> it's not a tap
[22:27:21] <ssi> have a picture of the tool?+
[22:27:24] <toastyde2th> the teeth are all in line with each other, there's no helix
[22:27:30] <ssi> cause there's some sorcery that I'm not getting here
[22:27:30] <Tom_itx> Connor, try 4000 s 30 f
[22:27:38] <ssi> yeah I understand what a thread mill is
[22:27:57] <Tom_itx> toastyde2th, i get it now
[22:28:00] <toastyde2th> i can cut the same thread with the same motions at any speed
[22:28:10] <ssi> er wait
[22:28:10] <Tom_itx> if it were like a tap it would strip the thread
[22:28:12] <ssi> never mind you're right
[22:28:58] <Tom_itx> but that's why they call out a thread pitch for the cutter
[22:29:06] <ssi> yea
[22:29:13] <ssi> you could still do it with a single point cutter but it would be slower
[22:29:18] <Tom_itx> they probably have to thin it out for smaller pitch
[22:30:18] <toastyde2th> ya, single point cutters are slow but work just fine
[22:30:27] <toastyde2th> i don't like em because i'd rather just use a tap at that point
[22:30:40] <toastyde2th> form tapping at 1k rpm is pretty fast
[22:30:47] <Tom_itx> the only reason i would would be on a larger diameter
[22:30:48] <ssi> well I'd rather use a single point cutter than have to buy several goofy sizes of tap
[22:30:54] <toastyde2th> that's true
[22:31:04] <ssi> in order to do these ballnut mounts I need 15/16-16 and 1-1/4-18
[22:31:10] <toastyde2th> we didn't do a lot of stuff that was oddball sizes
[22:31:20] <ssi> so I'm going to singlepoint them on the lathe
[22:31:22] <toastyde2th> i could imagine them being super useful if i just wanted a particular pitch at an arbitrary size
[22:31:35] <ssi> I actually have that need a lot doing gun work
[22:31:50] <ssi> truing a receiver means taking a nominal size thread and making it oversized
[22:31:57] <ssi> and then cutting a barrel to that oversized spec
[22:32:42] <toastyde2th> yeah, you'd probably fall in love with threadmills then
[22:32:49] <ssi> well it's mostly lathe work
[22:33:04] <ssi> also all needs to be concentric and square to a tenth
[22:34:11] <toastyde2th> that's kind of an exciting requirement
[22:34:15] <ssi> yea
[22:34:18] <ssi> gets set up like so:
[22:34:18] <ssi> https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-frc1/303191_725209428042_2131740446_n.jpg
[22:34:29] <ssi> the fixture is a big piece of pipe, and has bolt spiders on both ends
[22:34:37] <ssi> the receiver sits in there, and there are precision bushings in the bolt raceway
[22:34:44] <ssi> and then that piece of thompson shaft through the bushings
[22:34:51] <ssi> then you dial in the rod so it's running true on both ends
[22:35:01] <ssi> that gets it parallel to the spindle and concentric to a tenth
[22:36:09] <ssi> then the face is cut square and the internal thread is recut oversize, and the inside lugs are cut square
[22:36:19] <ssi> then, the barrel gets a tenon turned and threaded to that oversized thread
[22:36:23] <ssi> and then it's test fit thusly:
[22:36:23] <ssi> https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-ash4/399878_775108450002_1069079313_n.jpg
[22:37:14] <ssi> then a chamber cut
[22:37:16] <toastyde2th> wow
[22:37:25] <toastyde2th> tbh i've never tried to line up something on a 4 jaw to a tenth
[22:37:31] <ssi> and then eventually you thread the muzzle and mill a stock inlet and then throw a suppressor mount on it
[22:37:35] <ssi> https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-ash4/422975_783007844552_1937769465_n.jpg
[22:37:39] <ssi> and then your friends start to get jealous
[22:37:41] <ssi> that's the fun part
[22:38:24] <Valen> what caliber?
[22:38:29] <ssi> 30-06
[22:39:55] <ssi> toastyde2th: 4jaw is the only way to fly if you are trying to cut something with existing features
[22:40:00] <ssi> if you care about any level of precision that is
[22:40:37] <ssi> it's not that bad... just dial it in on a +/-30 0.001 indicator, then put a tenths dial on it
[22:41:09] <Valen> whats a tenth in mm?
[22:41:26] <Tom_itx> Valen, hair on a gnat's arse
[22:41:38] <toastyde2th> ssi, yeah, i agree
[22:41:42] <Valen> still sounds like an imperial measurement to me Tom_itx ;->
[22:41:53] <ssi> Valen: 2.5um I think?
[22:42:02] <Valen> pretty teensy
[22:42:04] <toastyde2th> also, for very very high precision work I usually use soft jaws on a 3 jaw chuck and a clocking mark
[22:42:18] <toastyde2th> if it's concentric
[22:42:22] <ssi> 0.00254mm
[22:42:25] <ssi> that's 2.5um, ye?
[22:42:39] <ssi> metric system is so complicated ;)
[22:42:41] <Valen> I always just use decimal points
[22:42:53] <ssi> it's a tenth of whatever a mil is in mm
[22:42:53] <ssi> heheh
[22:43:03] <Valen> the prefixes allow too much confusion in "mixed company" ;->
[22:43:12] <Valen> also I suck at remembering them lol
[22:43:25] <ssi> and I think 1um is 1 micron
[22:43:32] <ssi> and micron is an awesome name
[22:43:38] <ssi> like some sort of tiny superhero
[22:44:33] <Valen> lol!
[22:44:53] <Valen> 1 micron = 0.001 millimetres
[22:44:58] <ssi> yea
[22:45:01] <ssi> 1um :D
[22:45:15] <Valen> A micrometre or micrometer (pron.: /ˈmaɪkroʊmiːtər/, symbol µm)
[22:45:17] <Valen> yup
[22:45:31] <Valen> The term micron and the symbol µ, representing the micrometre, were officially accepted between 1879 and 1967, but officially revoked by the ISI in 1967
[22:45:39] <ssi> lol
[22:45:55] <ssi> so what, only m and mm are acceptable units now?
[22:46:03] <ssi> and km I guess
[22:46:24] <ssi> silly metric
[22:46:33] <Valen> micrometer is acceptable
[22:46:36] <Valen> micron isnt
[22:46:37] <ssi> ILL REPRESENT MY DISTANCES WITH WHATEVER PRECISION I PLEASE
[22:47:10] <generic_nick|3> yards
[22:47:27] <ssi> the distance to the sun is 1.496e17 um
[22:47:30] <ssi> suck it ISI
[22:47:44] <Valen> and i bet your car gets 2 hogheads to the furlong
[22:48:03] <ssi> shit I wish
[22:48:24] <generic_nick|3> i wish. more like 1/4 a hampster nad
[22:48:53] <Valen> our mill has 1um glass scales on it does that count?
[22:48:53] <ssi> hang on I want to work this out now
[22:49:00] <Valen> heh
[22:49:03] <ssi> Valen: that's nice actually
[22:49:06] <Valen> 3–4 µm — size of a typical yeast cell
[22:49:09] <ssi> my mill has 0.0002" scales
[22:49:13] <ssi> which'd be about 5um
[22:49:21] <Valen> thats the next "grade" up
[22:49:26] <ssi> yea
[22:49:28] <Valen> I use them to close the servo loop
[22:49:29] <ssi> mine are fairly cheap
[22:49:34] <ssi> but for manual mill DRO, it's FINE
[22:49:50] <Valen> I wish i had put encoders on the motors for velocity feedback
[22:50:00] <generic_nick|3> there's a dro on part of a scrapped mill at the metal recyclers.
[22:50:08] <ssi> the velocity component on your encoder counters in hal not good enough?
[22:50:13] <generic_nick|3> im trying to see what they want for it. it's a newer one too
[22:50:25] <Valen> too much mechanical noise between the motor and the sensor I think
[22:50:28] <ssi> ah
[22:50:49] <ssi> you need the velocity feedback at the drive or just in hal?
[22:50:55] <Valen> hal
[22:51:01] <Valen> I'm using mesa drives
[22:51:02] <ssi> what are your motors?
[22:51:08] <Valen> 500W scooter motors ;->
[22:51:12] <ssi> lolol
[22:51:19] <Valen> ey they work
[22:51:25] <Valen> and the right price
[22:51:29] <ssi> did you see my nema23 stepper encoder mounts?
[22:51:44] <Valen> http://www.youtube.com/watch?v=frIssODebKA&list=PL04F6B774F23F6873
[22:51:45] <Tecan> (frIssODebKA) "3600mm/minute 9600RPM 4 flute 6mm cutter" by "zyeborm" is "Tech" - Length: 0:00:24
[22:51:45] <ssi> https://pbs.twimg.com/media/BJxJMQICEAAO_GV.jpg:large
[22:52:03] <Valen> 3d printed?
[22:52:10] <ssi> yep
[22:52:26] <Valen> ewwwy ewwey ;->
[22:52:39] <generic_nick|3> i ordered 3 of these to make my spindle disk encoder on my mill. http://www.mouser.com/Search/ProductDetail.aspx?R=OPB912W55Zvirtualkey54210000virtualkey828-OPB912W55Z
[22:52:41] <ssi> sure, be derisive
[22:52:44] <ssi> it works, and it was cheap :)
[22:53:05] <ssi> generic_nick|3: looks like the same ones I used on my little lathe
[22:53:07] <pcw_home> nice HS tapping/thread milling video
[22:53:09] <pcw_home> http://www.emuge.com/videos/1018_thread_making_demo.html
[22:53:19] <Valen> I was thinking of putting a print head on our mill
[22:53:22] <generic_nick|3> nice ssi, how did they work?
[22:53:36] <ssi> great:
[22:53:36] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-frc1/205204_655375525742_5631970_n.jpg
[22:53:41] <Valen> that is one holy chunk of metal
[22:53:50] <ssi> I needed schmitt triggers on them though
[22:54:01] <Valen> I'm trying to work out how to do servo drive on our new mill, it all just keeps winding up too expensive
[22:54:17] <generic_nick|3> they arent ttl ssi?
[22:54:27] <ssi> they're slow
[22:54:31] <ssi> I had poor rise times
[22:54:37] <generic_nick|3> really
[22:54:42] <Valen> weak perhaps?
[22:55:16] <ssi> so here's the before:
[22:55:17] <ssi> https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-snc6/p206x206/221664_655377352082_5844353_n.jpg
[22:55:23] <ssi> and after:
[22:55:23] <ssi> https://sphotos-a.xx.fbcdn.net/hphotos-snc6/207897_655377411962_259243_n.jpg
[22:55:34] <generic_nick|3> they say 70ns. that's pretty fast
[22:56:42] <ssi> you may have better luck than I did
[22:56:51] <generic_nick|3> they have ones that look the same but need pullup resistors, sure it wasnt one of those?
[22:56:55] <Valen> i think my scope is the last one they made before they went digital
[22:56:58] <ssi> maybe
[22:57:07] <Valen> well for their main line anyway
[22:57:15] <generic_nick|3> ssi: i hope so, im not good with fixing that kinda crap lol
[22:57:16] <Valen> still its really rather better than my last one
[22:57:19] <Valen> tube based
[22:57:46] <generic_nick|3> ssi: what did you use for the index? a hole inboard of the notches or something?
[22:57:51] <ssi> a deeper notch
[22:57:56] <ssi> you can see it in the pic with the disk
[22:58:19] <generic_nick|3> you just moved the index sensor in a little so it didnt trigger on the a/b notches?
[22:58:21] <Valen> I was thinking of using those magnetic encoders
[22:58:22] <ssi> yep
[22:58:29] <generic_nick|3> gotcha
[22:59:01] <generic_nick|3> thats what i had planned, but wasnt sure if there was enough throat on the sensor
[22:59:08] <ssi> yea there is
[22:59:12] <generic_nick|3> cool
[22:59:16] <ssi> I used the same sensors for limits on that machine
[22:59:27] <ssi> they're not as repeatable as I'd like
[22:59:35] <ssi> for homes that is
[22:59:44] <generic_nick|3> for the price, its hard to beat
[22:59:46] <ssi> yea
[23:00:17] <generic_nick|3> what's your spindle rpm?
[23:00:30] <ssi> I don't tend to run much over 3k
[23:00:45] <ssi> I can run it up to 6k I think
[23:00:46] <generic_nick|3> my spindle revs 6k
[23:00:46] <ssi> but I don't like to
[23:00:56] <generic_nick|3> hoping it doesnt loose count
[23:01:10] <ssi> oh I have no problem with counting it at 6k
[23:01:16] <ssi> I just don't like spinning big heavy lathe chucks that fast :)
[23:01:17] <generic_nick|3> i only need it for rigid tapping, which will be at a low rpm anyways
[23:01:29] <generic_nick|3> gotcha
[23:01:49] <ssi> and the bearings in the headstock aren't great and they get hot
[23:02:19] <generic_nick|3> yea i dont even run my hardinge over 700
[23:02:46] <generic_nick|3> wait is that on your hnc?
[23:02:51] <ssi> no on my g0602
[23:02:54] <generic_nick|3> ah
[23:02:55] <ssi> hnc has a factory encder
[23:02:58] <ssi> you know that :P
[23:03:00] <ssi> resolver rather
[23:03:11] <generic_nick|3> mine was a resolver but i swapped it for an encoder
[23:03:55] <generic_nick|3> i was thinking of changing the pulley ratio to get some more velocity out of my servos on the hnc
[23:04:11] <ssi> I'm not unhappy with the speed of the HNC
[23:04:16] <ssi> it's not the fastest in the world, but it's adequate
[23:04:19] <ssi> and it's PRECISE
[23:04:32] <generic_nick|3> im getting 200ipm again (thanks to you)
[23:04:35] <ssi> :D
[23:04:46] <ssi> that's plenty fast enough for that little machine
[23:04:51] <ssi> it's only got a couple inches of travel in each direction
[23:04:59] <generic_nick|3> ill be doing heavy production on it soon
[23:05:07] <ssi> making what?
[23:05:07] <generic_nick|3> every second counts
[23:05:21] <generic_nick|3> skateboard trucks... titanium spindles for them
[23:05:23] <ssi> aha
[23:05:29] <ssi> I've never machined titanium
[23:05:41] <Tom_itx> lower rpm and constant feed
[23:05:47] <Tom_itx> or it will work harden
[23:05:51] <generic_nick|3> http://farm9.staticflickr.com/8395/8704736685_63028c81dd_c.jpg
[23:06:04] <ssi> very cool
[23:06:07] <ssi> you make the bodies of them too?
[23:06:11] <generic_nick|3> 6-4 ti cuts great
[23:06:12] <generic_nick|3> yes
[23:06:17] <ssi> excellent :)
[23:06:17] <generic_nick|3> thanks
[23:06:28] <generic_nick|3> emc2 at work :)
[23:06:30] <ssi> yeah
[23:06:38] <ssi> I have one production job I do on my hnc
[23:06:43] <Tom_itx> generic_nick|3, what sort of feed/speed are you running on it?
[23:06:44] <ssi> and my customer has been waiting on parts for awhile
[23:06:47] <ssi> and my machine is down :(
[23:06:51] <Tom_itx> vs cutter diameter...
[23:07:28] <generic_nick|3> Tom_itx: i run about 230sfm, .013" per rev for roughing
[23:07:44] <generic_nick|3> conservative
[23:07:51] <Tom_itx> what rpm?
[23:08:00] <generic_nick|3> on these parts ill push the limit a little more
[23:08:25] <generic_nick|3> i dunno, i run g96 s230
[23:08:31] <generic_nick|3> depends on diameter
[23:08:55] <Tom_itx> lathe?
[23:08:58] <generic_nick|3> yes
[23:09:11] <Tom_itx> oh i thought you were milling the whole thing
[23:09:33] <generic_nick|3> i thought you asked about the ti spindles
[23:09:41] <Tom_itx> i was
[23:09:47] <Tom_itx> i thought the whole thing was
[23:09:48] <generic_nick|3> the hanger and base are aluminum
[23:09:49] <Tom_itx> ti
[23:09:52] <Tom_itx> ok
[23:09:57] <generic_nick|3> only the hardware is ti
[23:10:19] <ssi> hm so if I make XL belt reductions, I'll have to od grind the ballscrew end down to 1/4" (which I think I need to do anyway
[23:10:29] <ssi> and then I can run a 14 to 48 reduction cheap enough
[23:10:34] <ssi> or 14 to 60
[23:10:42] <ssi> 14:48 is 1:3.43
[23:10:55] <generic_nick|3> the hanger and base take about 10-12 minutes total, i havent made the fixtures or dialed in the program yet so that time is based on prototyping
[23:10:59] <ssi> that'd make my max screw speed 1550rpm
[23:11:08] <ssi> max travel speed 310ipm
[23:11:10] <ssi> that sounds pretty sane
[23:11:19] <generic_nick|3> ssi: on what?
[23:11:22] <ssi> g0704
[23:11:29] <ssi> 5/8" ballscrews
[23:11:31] <generic_nick|3> gotcha
[23:11:43] <ssi> I was looking at what direct coupling these servos would mean
[23:11:47] <ssi> they're 5300rpm servos at 60v
[23:11:52] <ssi> that's too damn fast for screws
[23:12:07] <generic_nick|3> yea thats fast
[23:12:10] <ssi> or maybe I Take the easy way out and buy a nema23 slow servo from keling
[23:12:26] <ssi> except theirs don't come with encoders
[23:12:44] <ssi> oh and they're still fairly fast
[23:13:42] <generic_nick|3> does the plasma cause any electrical noise that may interfere with the cnc portion?
[23:13:53] <ssi> I haven't had any problems with it
[23:14:14] <generic_nick|3> i know if i use the plasma near my desktop in the garage, my usb devices need to be unplugged and plugged back in
[23:14:22] <ssi> that's annoying
[23:14:25] <generic_nick|3> yea
[23:14:54] <generic_nick|3> hmmm wonder if the garage floor is dry enough to lay a coat of paint on it tonight
[23:15:18] <generic_nick|3> i want it to dry for 12-15 hours before i move stuff onto it
[23:50:23] <PetefromTn> ...
[23:51:49] <PetefromTn> This thing on? First time chatting on my Android phone.
[23:56:03] <generic_nick|3> wow that paint soaked in. gunna need a couple coats or so
[23:56:07] <PetefromTn> Hello?
[23:57:52] <generic_nick|3> hello
[23:58:32] <PetefromTn> I say I say can ya hear me my good man?
[23:58:32] <generic_nick|3> is it me you're looking for?
[23:58:48] <generic_nick|3> cause i wonder where you are
[23:58:59] <generic_nick|3> and i wonder what you do
[23:59:24] <generic_nick|3> are you somewhere feeling lonely, or is there someone loving you?
[23:59:40] <PetefromTn> Smartass...
[23:59:48] <generic_nick|3> ha
