[00:02:41] <Tom_itx> was getting 34 for ya
[00:02:51] <Tom_itx> gotta unload the car first
[00:09:08] <Tom_itx> zeeshan|2
[00:11:51] <zeeshan|2> http://i.imgur.com/TihMrqP.png
[00:11:52] <zeeshan|2> tom
[00:11:53] <zeeshan|2> lol
[00:11:56] <zeeshan|2> i didnt have the drawing
[00:12:01] <zeeshan|2> but i tried to make it to by eyeball
[00:12:10] <zeeshan|2> did yuou do it similar to that?
[00:12:57] <Tom_itx> yeah
[00:13:11] <Tom_itx> the dwg is there now
[00:13:16] <zeeshan|2> thank you
[00:13:17] <zeeshan|2> dude
[00:13:18] <Tom_itx> some reason it didn't load for me
[00:13:19] <zeeshan|2> after using inventor
[00:13:26] <zeeshan|2> i realize how many shortcuts i dont know for solidworks
[00:13:28] <zeeshan|2> i use the gui too much
[00:13:33] <zeeshan|2> like for example starting a sketch on a plane
[00:13:41] <zeeshan|2> i press s in inventor
[00:13:43] <Jymmm> ...instead of a train!
[00:13:46] <Tom_itx> gotta go.. mrs just got in from an 18 hr drive
[00:13:51] <Tom_itx> later...
[00:13:52] <zeeshan|2> oki :P
[00:13:53] <zeeshan|2> cya!
[00:17:44] <bobo__> zeeshan|two good luck tomorrow
[00:18:27] <zeeshan|2> thank you
[00:18:28] <zeeshan|2> bobo
[00:18:31] <zeeshan|2> is your name spanish
[00:18:50] <bobo__> not yet
[00:18:58] <zeeshan|2> it means fool in spanish!
[00:19:08] <zeeshan|2> my wifey told me this the other day
[00:19:08] <zeeshan|2> :)
[00:19:15] <zeeshan|2> she keeps calling me bobo now
[00:19:52] <Jymmm> zeeshan in english means stinky poo poo head!
[00:20:29] <bobo__> it should be fool in english,from some of recent goings on
[00:20:47] <zeeshan|2> what do you mean
[00:21:12] <Jymmm> zeeshan|2: (psss, you halo is crooked)
[00:21:13] <bobo__> just stuff in my life
[00:21:29] <zeeshan|2> did you miss out on a machine? :D
[00:21:56] <Jymmm> bobo__: Either LICK IT or have more tequilia, either way it'll be an adventure!
[00:22:44] <toastyde1th> Erant, yep
[00:22:54] <bobo__> sometimes the bar bill gets too high
[00:23:07] <toastyde1th> remember that on a roughing endmill the chip load is not feed divided by the number of teeth
[00:23:19] <Jymmm> bobo__: Less drinking, MORE LICKING then!
[00:23:21] <toastyde1th> but they publish numbers as though it were
[00:23:46] <toastyde1th> and also, with roughing, you want to go very slow. people try to go too much for speed and fall behind on feed rate, when feed is vastly more important
[00:24:28] <Jymmm> http://imgur.com/tMSwESY
[00:24:33] <bobo__> missed out on getting the garage done
[00:24:47] <zeeshan|2> bobo__: winter is here
[00:24:51] <zeeshan|2> you can get it done :)
[00:25:24] <Jymmm> Not mine, but I actually do have a neighbor that has mini donkeys. When she walks them, they will stop at my place and refuse to move till I bring them their carrots =)
[00:27:54] <bobo__> no problem ,eah . come on over after the interview tomorrow and we will put in the concrete floor
[00:28:35] <bobo__> you can tell me how the cats are doing
[00:33:24] <zeeshan|2> hehe
[02:24:19] <Deejay> moin
[03:33:28] <Loetmichel2> *harhar* just found my thumbdrive with my timesheets in it... desperately seeked for a month... in the shopvac underneath the workbench ;-) (had to open it because accidentally sucked up some parts)
[04:21:39] <archivist> big spindle? http://www.ebay.co.uk/itm/Cutler-Hammer-SVX9000-AC-Drives-Model-SVX100A1-4A1N1-100HP-NEW-/262191498843
[04:23:06] <Contract_Pilot> LCNC first movements.
[04:23:11] <Contract_Pilot> https://youtu.be/VTh52gv0524
[04:23:44] <Contract_Pilot> Now to learn more on HAL and the INI so i can get Path Pilot up.
[04:24:14] <cncbasher> now theirs the nightmare ? , what do you need
[05:09:51] <jthornton> morning
[06:15:15] <XXCoder> Contract_Pilot: heh that is a fun stage
[06:15:23] <XXCoder> spinny flags
[07:12:44] <jthornton> crumb, the helloworld gladevcp example does not work
[07:13:45] <Tom_itx> bugger when sample code doesn't run
[07:17:12] <jthornton> yea it's bad when the most simple one fails to work
[07:25:49] <_methods> i had to get reading glasses :9
[07:25:53] <_methods> can't read prints anymore
[07:26:01] <_methods> gettin old sucks
[07:26:37] <archivist> and then two pairs stacked
[07:26:43] <_methods> oh man
[07:26:48] <_methods> plz dont tell me that happens
[07:27:12] <jthornton> I hate to tell you but it don't get better...
[07:27:31] <_methods> thanks for the pick me up lol
[07:27:35] <archivist> may I recommend a stereo zoom microscope
[07:27:51] <_methods> i want to get a monocle
[07:27:53] <_methods> lol
[07:28:05] <_methods> and a top hat
[07:29:07] <archivist> microscope above the lathe is very useful
[07:29:35] <_methods> i'm so used to being able to read microchip labels
[07:29:39] <_methods> now i can't see any of them
[07:30:31] <jthornton> yea, one day I could not read the MSC catalog very well...
[07:30:43] <_methods> ouch
[07:30:46] <jthornton> that sucked
[07:30:55] <jthornton> at least I can see far ok
[07:30:58] <archivist> electronics was the day job....
[07:31:10] <_methods> yeah i can see fine
[07:31:50] <_methods> far
[07:32:01] <_methods> apparently not close now
[07:32:15] <Tom_itx> there are still printed words???
[07:32:17] <Tom_itx> :)
[07:32:18] <archivist> you must be 40+
[07:32:27] <_methods> yeah
[07:33:01] <_methods> i guess i'll have to start wearing diapers soon
[07:33:03] <_methods> hahahahaha
[07:34:12] <archivist> getting to the age where one has to be careful with farts
[07:34:30] <_methods> hahaha
[07:34:32] <Tom_itx> ghastly
[07:34:51] <_methods> not looking forward to that one bit
[08:05:54] <jthornton> an older friend of mine kinda gave up when his wife died, then he lost his house last Dec 24th and his son put him in a nursing home a couple of weeks ago, I don't think he will see 80
[08:06:09] <jthornton> it's sad that he gave up on life
[08:07:50] <MrSunshine> https://www.youtube.com/watch?v=zR3abFbgXUw interesting about cylinder squares and stuff =)
[08:17:21] <knas> has anyone gotten camview-emc running under linuxcnc 2.7 wheezy? having no luck neither downloading directly from apt or compiling the source...
[08:20:48] <Erant> toastyde1th: k, just wanted to check that that's a decent starting point. The IPM seemed low to me.
[08:25:40] <gregcnc> So what's this about roughing endmill feedrate?
[08:29:23] <zeeshan|2> gregcnc: youre a roughing end mill!
[08:30:48] <gregcnc> Hi Zee. I've only used them a couple times. I want to use one in a part I'm setting up. Never read anything about feeding them differently.
[08:31:07] <zeeshan|2> gregcnc: they can handle more chip load
[08:32:31] <gregcnc> someone wrote "that on a roughing endmill the chip load is not feed divided by the number of teeth "
[08:34:40] <zeeshan|2> sounds like they dont understand how to calculate velocity
[08:34:46] <zeeshan|2> :P
[08:35:57] <gregcnc> it doesn't sound right to me either. Swiftcarb has some high feedrates for their aluminum roughers.
[08:38:06] <zeeshan|2> from what ive seen you can easily put a 3/8 end mill to .005 chip load no prob
[08:38:12] <zeeshan|2> (rougher)
[08:49:20] <zeeshan|2> gregcnc: the other night i was pushing my machine to the limit
[08:49:38] <gregcnc> radial engagement (chip thinning) accounted for?
[08:51:04] <zeeshan|2> in what
[08:51:07] <zeeshan|2> the .005 feedrate?
[08:51:10] <gregcnc> yes
[08:51:13] <zeeshan|2> no
[08:51:16] <zeeshan|2> that is for simple slotting
[08:51:46] <gregcnc> OK full chip axial depth
[08:52:05] <gregcnc> what was axial depth?
[08:54:03] <zeeshan|2> 1/4"
[08:54:14] <zeeshan|2> 3 flute
[08:54:25] <zeeshan|2> need lube and serious chip evac
[08:54:44] <gregcnc> right
[08:55:17] <zeeshan|2> i think thats the biggest problem in damn aluminum
[08:55:20] <zeeshan|2> gummy chips
[08:55:25] <zeeshan|2> when youre going super fast
[08:55:48] <zeeshan|2> (even with a roughing end mill)
[08:56:29] <gregcnc> you pretty much need through spindle if you want to get crazy
[08:56:41] <zeeshan|2> ive been pushing my mitusbishi apx cutters to the limits
[08:56:44] <zeeshan|2> they are so bad ass
[08:56:51] <zeeshan|2> i usually baby them
[08:57:13] <zeeshan|2> but now im running them at the recommended speeds:
[08:57:59] <gregcnc> babying tools is waste of time and tool life, as long as you have enough power and rigidity behind it
[08:58:00] <zeeshan|2> mild steel -> @ doc of .276 max, 0.007 ipt, pitch of helical cutting .079
[08:58:10] <zeeshan|2> 550 sfm
[08:58:44] <zeeshan|2> i was taking .1" width of cuts at a depth of .5"
[08:58:48] <zeeshan|2> depth of cut of
[08:58:53] <zeeshan|2> when the helix ramp was complete
[08:59:00] <zeeshan|2> holy cow does it remove metal
[08:59:19] <gregcnc> which machine
[08:59:26] <zeeshan|2> my little baby mikron wf21c
[08:59:42] <zeeshan|2> i have a burn on my forehead
[08:59:44] <zeeshan|2> and neck
[08:59:48] <zeeshan|2> from the chips lol
[09:03:46] <irontree9> I am just dealing with a cheap rotory tool. Dealt with my fir bit jam yesterday. I was lucky the work broke lose and the machine survived. Going to wire up a better kill switch. Clicking a mouse is impossible in a panic.
[09:04:44] <gregcnc> Escape button?
[09:04:56] <zeeshan|2> irontree9
[09:04:58] <zeeshan|2> if youre using linuxcnc
[09:05:02] <zeeshan|2> pressing escape works! :D
[09:05:23] <irontree9> Hell yeah, thanks guys.
[09:06:14] <gregcnc> Watching your Chiron clips Zeeshan. I need to move before i can get a real machine.
[09:06:25] <gregcnc> Mikron
[09:16:38] <ssi> MORN
[09:18:41] <irontree9> Anyone have any good ideas about securing the work piece. My Z-axis is real high and I have to lift up all the work when I mount it. Atm I am just testing using adhesive and blocks.
[09:20:52] <cradek> have a picture?
[09:21:13] <irontree9> have a video brb
[09:22:31] <irontree9> https://www.facebook.com/video.php?v=1045012402205144&pnref=story
[09:22:47] <irontree9> video of the first g-code going through the machine
[09:24:31] <cradek> can you redesign the dremel holder so it can allow you to reach the table?
[09:25:57] <irontree9> I thought about using the rotory extender and mount that but it adds allot of play in the Z
[09:26:14] <irontree9> I figure building up the table would be easier
[09:26:33] <_methods> just screw the workpiece to your table
[09:26:40] <Jymmm> Um, remove the thumb grip and use the threads
[09:27:06] <irontree9> brb let me check that out Jymmm
[09:27:25] <_methods> and remap the stop to your spacebar so it's easier to hit
[09:27:53] <_methods> if you don't have an estop hooked up
[09:30:14] <irontree9> Jymmm, The extender goes to a grinder and it is pretty cheap. I would have to cut a bearing holder that drops down.
[09:31:02] <irontree9> I think I am going to just bolt everything up but yeah all I have is soft limits.
[09:31:11] <Erant> gregcnc: I'm wanting to use a rougher for aluminum. 3/8".
[09:31:26] <Erant> gregcnc: It's a Melin, and they're recommending a 0.00225" chipload.
[09:31:48] <Jymmm> Dremel produced a stand that turned the tool into a drill press. That stand had a bracket that held the tool, but it was "universal" in the respect that it could be attached to anything using just a couple of bolts.
[09:31:54] <Erant> And 250SFM for alu alloy, which comes out to 15-20IPM @ 2.5k RPM
[09:32:11] <Jymmm> If you can find the parts list, you can order just the bracket from dremel directly
[09:32:17] <gregcnc> Erant, Carbide?
[09:32:22] <Erant> Which is probably more than my machine can handle anyway at anything but the shallowest cuts.
[09:32:29] <Erant> HS Cobalt.
[09:32:32] <Erant> So, HSS.
[09:32:53] <gregcnc> That's why the numbers are low.
[09:33:37] <Erant> I ran a 4 flute through 6061 (because my 2 flute was dull as shit) at 0.05" DOC, slotting, 20IPM.
[09:33:46] <Erant> Little over 2.5k RPM.
[09:34:09] <Erant> So I'm curious if I should just increase the engagement a little with the rougher?
[09:34:21] <irontree9> Yeah I had to replace that dremel with a cheap knock off so it doesn't match. However great idea Jymmm, looking at the stand now
[09:34:38] <Jymmm> Here it is... http://www.ebay.com/itm/Dremel-Moto-Tool-Deluxe-Drill-Press-Stand-Model-212-/151917016780
[09:35:48] <irontree9> nice
[09:37:03] <Jymmm> http://stevespages.com/pdf/dremel_drill_press_stand.pdf
[09:37:04] <irontree9> tbh I was going to break out my micrometer, measure, scratch out some sketchy gcode and cut my own.
[09:37:45] <Jymmm> Dremel PN 5294206, Moto Tool Holder Bracket
[09:38:08] <Jymmm> PDF page 5, item #7
[09:38:44] <Jymmm> #6 and #24 too
[09:39:03] <gregcnc> Erant is this what you're looking at? http://www.endmill.com/pages/catalogs/2012/Sections/133-146%20-%20Cobalt%20and%20HSS%20Roughers.pdf
[09:45:51] <irontree9> seems that my emergency stop is keyed to F1
[10:00:20] <gregcnc> Is there a DC brushless, 48V, servo control that takes step and direction input? Like a G320, but brushless?
[10:00:52] <archivist> you dont really want step dir do you
[10:01:06] <gregcnc> No, but you can't get a 7i77 if you try
[10:01:26] <gregcnc> i'm considering pico upc tough
[10:02:44] <ssi> man this 7i77 shortage is a disaster :(
[10:03:51] <archivist> just have a little patience
[10:04:21] <gregcnc> had some, but it ran out
[10:06:15] <archivist> I had the fun of being production manager with a 3 month backlog once :)
[10:22:24] <Jymmm> archivist: Um, wouldn't that make you a sucky product manager?
[10:26:08] <Jymmm> Our division only had one (very high end) product, but the founder/chief engineer went up and died on us, and so did the division 24 months later.
[10:28:53] <archivist> Jymmm, nope, the cause was high demand and Canon could not supply enough product
[10:29:46] <Jymmm> What, not enough child/slave labor to make more?
[10:29:47] <archivist> it is very hard when you take a third of a companies worldwide production of one thing
[10:30:37] <Jymmm> archivist: You worked for Canon or ???
[10:31:01] <archivist> a two bit company that got lucky with a printer for a while
[10:31:38] <Jymmm> ah
[10:32:15] <archivist> we were selling canons A1210/PJ1080 into UK education
[10:32:41] <Jymmm> Hmmm, I just FELT an aircraft. I dont thik thats a good thing in the forest at 3000ft elevation.
[10:32:45] <archivist> but with our name on
[10:32:54] <irontree9> okay dumb question. I am trying to calibrate this thing and I got the measurements correct. However what would cause a stepper motor to lock up when the feed is increased.
[10:32:56] <Jymmm> ah rebranding.
[10:33:12] <archivist> we changed the ROM and made it do more
[10:33:13] <Jymmm> irontree9: That's called stalling
[10:33:26] <irontree9> ah
[10:33:32] <archivist> back off a bit
[10:33:33] <Jymmm> It's a trait of ALL stepper motors.
[10:33:47] <archivist> never accelerate too fast
[10:34:16] <Jymmm> There are some drivers that can prevent it though.
[10:34:35] <archivist> reduce, not prevent
[10:34:41] <irontree9> yeah I keep turning it down, got it at 8mm/min
[10:34:48] <Jymmm> irontree9: http://www.geckodrive.com/support/step-motor-basics.html
[10:34:58] <irontree9> thanks
[11:16:06] <pcw_home> ssi: 7I77s are available
[11:16:41] <gregcnc> That's great! How long will it take to get through shipping backlog?
[11:17:06] <pcw_home> still about 3-4 weeks
[11:17:40] <ssi> good
[11:17:48] <ssi> I have a couple on hand but I think I have fewer than I have machines that need them :P
[11:19:31] <pcw_home> 7I76s are available also but I wont put them on the store yet at least until we have a chance to catch up
[11:20:26] <gregcnc> if ordered 3 -4weeks ago?
[11:24:23] <pcw_home> if you did it will likely go out this week
[12:04:01] <archivist> what does rb stand for as a wire colour in german?
[12:04:16] <archivist> I think is is pink....
[12:04:20] <archivist> it is
[12:04:52] <archivist> just decoding a label off an ebay encoder http://www.archivist.info/cnc/screw_error/AMI_encoder.php
[12:05:43] <MrSunshine> gah i want a concrete floor foundation for my cnc :(
[12:09:34] <Magnifikus> https://www.dropbox.com/s/wcfmju9mo33mzpp/2015-12-15%2018.44.22.jpg?dl=0
[12:09:43] <Magnifikus> milled me a monitor holder :D
[12:10:08] <Loetmichel2> archivist: i would say red with blue stripes
[12:10:13] <Loetmichel2> Rotblau
[12:10:56] <archivist> but there is no red blue :)
[12:11:13] <Loetmichel2> then the rb is simply wrong
[12:11:27] <Loetmichel2> there is no single colour with the R and B in them in german
[12:11:39] <vexation> lol maybe rosafarben, though would be silly to use the b
[12:12:24] <archivist> that is the one part of the label with a scratch :(
[12:12:32] <archivist> rs?
[12:12:37] <vexation> would make sense
[12:12:41] <Loetmichel2> rs would fit
[12:12:48] <Loetmichel2> for "rosa" = Pink
[12:14:50] <archivist> under the microscope I can just about be sure of rs
[12:15:59] <archivist> web page updated, I might dare to power it up now
[12:16:46] <archivist> My complaints to the makers though for a crappy website with little data
[12:19:13] <duc> pcw_home: where you able to look up the status of order 1706 from a few weeks ago
[12:19:46] <archivist> I found the brochure some time ago http://www.collection.archivist.info/archive/mirror/AMI/
[12:22:01] <vexation> Yeah brochure is an apt name for that.. bit shy of a datasheet
[12:22:58] <archivist> I get the impression of no standard versions
[12:23:51] <zeeshan|2> man i know this much
[12:23:54] <zeeshan|2> whatever company i work at
[12:23:58] <zeeshan|2> 7i77 needs to be implemented
[12:24:00] <zeeshan|2> =D
[12:26:20] <ssi> wat
[12:26:29] <zeeshan|2> i went to this awesome place today for an interview
[12:26:35] <zeeshan|2> theyre a huge automation company
[12:27:33] <zeeshan|2> lots of allen bradley control
[12:27:36] <zeeshan|2> and bechoff
[12:27:40] <zeeshan|2> i like the bechoff hmi
[12:29:26] <ssi> zeeshan|2: I guess I need to start building another control for this new mill :/
[12:29:30] <ssi> I don't think the other one is going to turn up
[12:29:33] <zeeshan|2> doh
[12:29:42] <zeeshan|2> what are you missinmg
[12:29:48] <ssi> drives and a 7i77
[12:29:56] <ssi> and the mating cannon plugs for the motor and power lines
[12:30:02] <ssi> and an enclosure
[12:30:05] <ssi> couple relays
[12:30:08] <zeeshan|2> $$
[12:30:12] <ssi> yeah.
[12:30:23] <ssi> I don't remember what the servo voltage is on it
[12:30:26] <ssi> probably 190v
[12:30:38] <zeeshan|2> brushless?
[12:30:41] <ssi> brushed
[12:30:46] <ssi> I think
[12:30:49] <ssi> again, it's been awhile :)
[12:30:59] <ssi> I'm pretty sure I used BE25A20 drives in the first one
[12:31:22] <ssi> https://scontent-atl3-1.xx.fbcdn.net/hphotos-xfl1/t31.0-8/459136_10100131793367542_829866394_o.jpg
[12:31:32] <ssi> but yea there's only one phase hooked up
[12:31:35] <ssi> so they must be brush motors
[12:31:57] <ssi> dammit I did such a good job on that control, it really irks me that it's missing :(
[12:32:29] <gregcnc> how'd you lose that?
[12:32:50] <ssi> I built it for a company, teh company went under and gave it to an electrical contractor that they couldn't pay, and he sold it to me
[12:32:59] <ssi> the whole mill, that is
[12:33:06] <ssi> somewhere in there, the control got lost
[12:33:21] <ssi> the folks at the company swear it was with the mill when the contractor picked it up, and gone after he took it
[12:33:25] <ssi> he swears he never had it
[12:33:39] <ssi> I swear I don't want to have to rebuild it :(
[12:33:48] <ssi> https://scontent-atl3-1.xx.fbcdn.net/hphotos-xaf1/v/t1.0-9/262501_10100133915824122_1848380283_n.jpg?oh=c0dc12e1f1da08e9ae4a730fdb17fe44&oe=571CAE7A
[12:33:53] <ssi> that's what it looked like installed in their shop
[12:34:15] <ssi> I got the computer and the arm with teh monitor and that bit of unistrut that was attached to the wall
[12:34:20] <ssi> but not the nema box itself
[12:34:29] <archivist> send the boys in to collect
[12:34:45] <ssi> srsly
[12:35:32] <ssi> I wish I could read the stickers on the edge of those drives in the pic
[12:35:41] <ssi> pretty sure it's BE25A20E tho
[12:37:26] <ssi> pcw_home: is there a 7i77e yet?
[12:38:11] <gregcnc> looks like bx25A20E, no encoder input
[12:38:36] <ssi> hey good catch
[12:38:43] <ssi> I've got it wired for tachs don't I
[12:39:26] <ssi> 30A8s are very plentiful but I'm pretty sure that those motors are well over 80V or I would have used the 30A8s
[12:39:30] <ssi> I had some on hand when I built that control
[12:40:24] <gregcnc> oops I think it reads BX15A20, that would make them 15A, 40-190V?
[12:40:44] <ssi> yeah
[12:40:49] <ssi> and the current is less critical than the voltage
[12:41:05] <ssi> most of those drives are way higher current rating than I need
[12:41:15] <ssi> but AMC as a rule makes 80V drives, 200V drives, and 400V drives
[12:41:36] <ssi> and I'll have to look but I bet those are 190V servos
[12:41:44] <ssi> 190v is 120vac rectified and filtered
[12:41:53] <ssi> and that's likely what the power supply in teh power cabinet is
[12:42:29] <ssi> I have five or six BE25A20AC drives on hand
[12:46:48] <maxcnc> hey all
[12:47:17] <gregcnc> I hope to be messing around with some AMC drives when the 7i77 comes, I have several to choose now. something should work.
[12:47:57] <maxcnc> most will work fine its a perfect BOB for the amc
[12:50:50] <ssi> yes, I've had great luck with amc drives and mesa servo interfaces
[12:51:58] <maxcnc> did pcw_home mamage his isllness and is back at work ?
[13:23:43] <maxcnc> if some starwors fans are here today is the german Startrek Xmas party its live on the net
[13:23:51] <maxcnc>
[13:23:54] <zeeshan|2> STAR WARSSSSSSSSSs
[13:25:18] <maxcnc> thee is troubel now with the conversion from klingon to federation technic towards the beamer ;-)
[13:39:57] <Tom_itx> zeeshan|2 was that one pdf ok? i wasn't able to open it online here
[13:46:13] <ssi> blahhh
[13:46:24] <anomynous_> what is the process of making chips called?
[13:47:02] <anomynous_> cutting? ;D
[13:47:18] <jdh> potato slicing
[13:47:21] <Tom_itx> grinding, machining, hacking, sawing etc
[13:47:41] <ssi> grinding doesn't make chips :D
[13:47:52] <ssi> neither does sawing really
[13:47:57] <ssi> although it's sort of a spectrum I guess
[13:48:18] <anomynous_> im looking for a specific book on sandvik site and i cant find it ;D I have it printed, but i cant find it in english
[13:48:21] <Tom_itx> what's that crap all over my shop floor by the grinder then?
[13:48:26] <ssi> dust
[13:52:09] <gregcnc> Title doesn't turn it up ont he sandvik site?
[13:55:23] <anomynous_> no i cant find it. Lastuavat työkalut , Techical handbook . It has a picture of a part with indexable drill, boring head, grooving thing, threading thing, indexable mill, boring bar and od turn operation.
[13:55:50] <anomynous_> technical handbook = tekninen käsikirja
[13:57:49] <anomynous_> lastuavat työkalut = cutting tools
[13:58:01] <CaptHindsight> dust <100um avg dia, chips >100um dia
[13:58:25] <CaptHindsight> dust/powder
[13:59:10] <CaptHindsight> flakes would have to be more flatter than more round
[13:59:41] <CaptHindsight> do chips have a defined shape?
[14:03:12] <anomynous_> https://www.anony.ws/i/2015/12/15/IMG_0736.jpg
[14:03:16] <anomynous_> like so
[14:03:20] <CaptHindsight> are all chips swarf, but not all swarf are chips?
[14:03:26] <anomynous_> where can i find that online?
[14:04:42] <anomynous_> CaptHindsight, all chips may be swarf if you only have grinding machines? :D
[14:04:59] <anomynous_> implies your chips.
[14:05:00] <CaptHindsight> chip, swarf or shaving? https://c2.staticflickr.com/4/3043/2964262410_458ed13e77_b.jpg
[14:05:08] <gregcnc> http://sandvik.ecbook.se/SE/us-en/Training_Handbook/
[14:05:46] <anomynous_> gregcnc, so its that
[14:05:53] <anomynous_> thanks... i saw it but i thought its different
[14:05:54] <gregcnc> Not sure is it?
[14:06:29] <anomynous_> didnt check it
[14:07:44] <anomynous_> its the same
[14:14:29] <ssi> leaks, drips, seeps, streaks, stains
[14:15:11] <gregcnc> interesting book. i was hoping it would have more details about specific cutting force.
[14:16:07] <anomynous_> i think you can determine it somehow... ;D
[14:21:24] <gregcnc> "all cutting data is based on 15 min tool life"
[14:40:45] <anomynous_> CaptHindsight, its machinist's serpentine
[14:40:55] <anomynous_> just don't cut your fingers
[14:42:14] <anomynous_> a guy told he cut a tendon by pulling a long jammed chip like that.
[14:50:27] <anomynous_> you might also call it jenkalastu
[14:50:48] <anomynous_> thread chip or something
[14:50:50] <anomynous_> :D
[14:52:16] <anomynous_> guess im going to sleep then
[15:54:08] <ssi> zeeshan|2: you around?
[16:17:42] <zeeshan|2> now i am
[16:20:29] <ssi> well then
[16:24:34] <jdh> did I mention that driving near atlanta vefor thanksgiving really sucks?
[16:24:43] <ssi> sucks after thanksgiving too
[16:24:47] <ssi> and before christmas
[16:24:51] <ssi> and pretty much every other time of the year
[16:24:55] <JT-Shop> http://gnipsel.com/images/shop/Siding14.jpg
[16:24:59] <ssi> I'm sitting at work dreading going home :'(
[16:25:02] <JT-Shop> http://gnipsel.com/images/shop/Siding15.jpg
[16:25:31] <jdh> we drove through friday night. not bad.
[16:25:33] <XXCoder> ssi: my old job it was bad on fridays. normal days, around 30 min drive. Fridays? can he hour and half
[16:25:43] <ssi> yeah... see
[16:25:55] <ssi> rush hour in atlanta starts at 2:30 and ends at 7:30
[16:26:04] <ssi> except on fridays, when it starts sometime thursday around lunchtime
[16:26:23] <JT-Shop> lol
[16:26:36] <ssi> I wish I was kidding :(
[16:26:37] <ssi> http://www.511ga.org/#Variable_Speed_control&zoom=4&lat=4008646.58026&lon=-9389299.5127
[16:27:14] <jdh> move!
[16:27:20] <ssi> where?
[16:27:30] <jdh> good point
[16:27:42] <XXCoder> ssi: doubt possible work at home on friday? heh
[16:27:52] <DaViruz> rush hour is when i see more than five cars on the way home from work
[16:27:52] <jdh> 40 more miles of .ga and I'll be in FL
[16:27:59] <XXCoder> thankfully my current work don't have friday, and finisges at 1:45 am besides.
[16:32:15] <Deejay> gn8
[17:01:49] <Valduare> hows it going everyone
[17:03:06] <irontree9> Just fine tunning my new machine :)
[17:03:35] <Valduare> wish I had one :)
[17:03:40] <Valduare> any pics?
[17:04:18] <irontree9> https://www.facebook.com/video.php?v=1045012402205144&pnref=story
[17:04:21] <irontree9> a video
[17:06:09] <Valduare> very fun
[17:06:34] <Valduare> is it much of an issue having a heavy head on these cnc machines
[17:06:50] <Valduare> wonder why you dont see more flex shaft power heads?
[17:07:05] <SpeedEvil> because flex shafts are shit
[17:07:21] <irontree9> ditto
[17:07:46] <Valduare> too much friction/heat?
[17:08:29] <SpeedEvil> they have terrible life, poor power transmission without being destroyed, lots of 'whip'
[17:08:59] <Valduare> how about pneumatic die grinders?
[17:09:17] <Valduare> (if you have a humongous compressor)
[17:10:03] <irontree9> I have a POS compressor
[17:11:07] <Valduare> heh http://aimlab.wpi.edu/includes/research/prism_motor.jpg here’s x,y,z pneumatic stepper motors
[17:12:58] <irontree9> How about steam turbine? :)
[17:14:56] <Valduare> punch card g-code would be fun to keep track of lol
[17:18:06] <Valduare> 3d printer guys hang out in here too?
[17:18:55] <tiwake> several
[17:19:48] <tiwake> Valduare: pretty sure something of everything hangs out here
[17:43:17] <JT-Shop> lol there was something tan floating in my glass of red... wine soaked pistachios are pretty good
[17:44:56] <toastyde1th> gregcnc, the whole point of a roughing endmill is that the chip load is not calculated by feed per rev/number of teeth
[17:46:11] <toastyde1th> the teeth on the mill are (on a high quality roughing endmill) positioned so that each tooth is the only cutting surface on the mill
[17:46:41] <toastyde1th> so that if you have .015" of feed per revolution on a 3 flute endmill, rather than having .005" per tooth, each tooth actually cuts the full .015"
[17:47:21] <toastyde1th> this is done for two reasons - the major reason is that larger chips require less power as the chip size grows (up to a limit)
[17:48:00] <toastyde1th> the other reason is that the chip load per tooth, and the cutting length of the endmill, are part of the gain/damping terms for chatter
[17:48:22] <toastyde1th> and both improve in a helpful way when using a roughing/toothed cutting tool
[17:55:18] <gregcnc> right, I got the impression from reading that greater depth of cut was more efficient in terms of specific cutting power. But feed rate is still whatever the book says.
[17:59:05] <toastyde1th> if you're measuring feed in IPM, yes
[17:59:15] <gregcnc> toastyde1th we could assume a 3 flute cutter would have only 33% of each flute cutting, but most have at least 50% and most carbide roughers much more.
[17:59:49] <toastyde1th> there are a wide range of types of roughers, so the 33% is for high quality, pure roughing endmills only
[18:00:05] <gregcnc> I've never seen one like that
[18:00:07] <toastyde1th> also ground so that they don't pull the hell out of the holder, which is another thing poor quality cutters do
[18:00:51] <gregcnc> I think some of it also come from chip thinning due to the angled cut at each tooth
[18:01:54] <toastyde1th> definitely
[18:05:38] <FloppyDisk> @toastyde1th I know minimal when it comes to cutters, roughing or not. Do you have a recommendation for a roughing cutter for aluminum where I have a bridge port and
[18:05:42] <FloppyDisk> not much coolant flowing?
[18:06:46] <toastyde1th> unfortunately not, I am really really bad with brand names and whatnot. but for what you described i'd recommend the following type of cutter in general, which any semi-reputable company should have:
[18:07:33] <toastyde1th> 3/4 inch diameter, 3 flute, with a non-cobalt/non-high-temp full roughing (the teeth do not have flat tips, they're round) endmill
[18:08:06] <CaptHindsight> maybe something from Shars, cheap and good for roughing
[18:08:07] <toastyde1th> you don't really need coolant on a roughing endmill, you turn them very slowly and try to maximize feed rate instead
[18:08:35] <FloppyDisk> Thanks - will make a note and look for one.
[18:08:42] <toastyde1th> any kind of cutting lube will help, doesn't have to be flowing. Kerosene and disel work well for aluminum.
[18:08:51] <toastyde1th> brush it on and walk away
[18:09:19] <gregcnc> lamp oil if you don't want it to smell
[18:09:37] <toastyde1th> if you have the budget, you want to hold the endmill in an *end mill holder*, not a collet
[18:09:40] <CaptHindsight> http://www.shars.com/products/cutting/end-mills?cutting_diameter=3%2F4&end_mill_category=Roughers
[18:10:46] <toastyde1th> on CaptHindsight's link, go for the M2 (M2AL) endmills
[18:10:51] <toastyde1th> not carbide or cobalt hss
[18:10:58] <CaptHindsight> only $13.75 (or less on ebay) http://www.shars.com/products/cutting/end-mills/3-4-x-5-8-m2al-4-flute-roughing-end-mill
[18:11:35] <FloppyDisk> ohhhhh... The first ones I saw were not $13.75 on the shars link. Thank you!
[18:11:48] <CaptHindsight> I got most of mine through giant lots on ebay
[18:12:07] <toastyde1th> also, get the full diameter shank ones.
[18:12:10] <toastyde1th> not step down
[18:12:24] <FloppyDisk> I've bought some on Ebay as well, but I did't know what needed and have a few cutters (not roughing) that I might not use...
[18:12:41] <toastyde1th> though you probably won't come across a rougher with a narrow shank in 3/4"
[18:13:29] <FloppyDisk> Sounds good - I have some tool holders (not collets) and will use those. Wouldn't have thought that, but I see your point on cutting forces.
[18:13:57] <toastyde1th> if you find you don't have the right holder, http://www.shars.com/products/toolholding-workholding/tool-holders?bore_diameter=3%2F4&shank_size=R8&toolholder_category=End+Mill+Holder
[18:14:35] <toastyde1th> r8 is not strong enough to resist the tension on the cutter using just collets
[18:14:38] <FloppyDisk> Oh my, that's a good price for a R8. I have NTMB30's...
[18:14:53] <toastyde1th> oh, sry - i just assumed you had an r8 spindle
[18:14:57] <CaptHindsight> and most of them are cut properly :)
[18:15:18] <CaptHindsight> I got one that was off center
[18:15:32] <CaptHindsight> for me they are a short drive for returns
[18:15:34] <gregcnc> probably that 1/1,000,000 right?
[18:15:39] <FloppyDisk> No worries - I appreciate you looking. There's so much out there that impossible to find it all.
[18:16:53] <gregcnc> capthindsight, where about IL are you? I'm in Crystal Lake
[18:18:00] <CaptHindsight> I have a lab just north of you in an underground bunker
[18:18:45] <toastyde1th> also, it may sound dumb? but facemills.
[18:19:04] <toastyde1th> bridgeports do pretty well with 2" and 3" facemills
[18:19:42] <toastyde1th> if you have some ebay patience, you can find older, HSS inserted facemills and resharpen them yourself on a bench grinder
[18:20:17] <CaptHindsight> http://www.use-enco.com/CGI/INLMK32?PARTPG=INSRAR2
[18:20:28] <toastyde1th> 404
[18:25:26] <CaptHindsight> Enco probably generates links just for your search
[18:26:31] <FloppyDisk> I had to register and login, but found m6 spiral point taps...
[18:27:23] <FloppyDisk> Yes - enco is bad that way, this is the first time in a long time I actrually looked at a page.
[18:27:29] <FloppyDisk> otherwise, got frustrated and left...
[18:27:55] <toastyde1th> might want to try a form tap before you buy a large set of taps
[18:28:21] <toastyde1th> they work damn well in manual milling machines
[18:28:49] <toastyde1th> if you're using a cnc w/ floating holder, do not buy and disregard
[18:29:34] <CaptHindsight> gregcnc: I'm probably in or drive through Crystal Lake almost daily
[18:29:46] <Sync_> toastyde1th: resharpening facemills on a bench grinder is not the best idea
[18:29:55] <Sync_> you want to grind them in place on a tool and die grinder
[18:29:58] <Sync_> as you want equal chipload
[18:30:13] <toastyde1th> older facemills, which is what i'm recommending, have a per-tooth slide to adjust that
[18:30:31] <gregcnc> I hate driving through town
[18:30:32] <toastyde1th> so all you need is a guide fence of some sort on your bench grinder and you're in business
[18:32:23] <CaptHindsight> http://www.majosoft.com/metalworking/assets/images/slagkop_frees_0011.jpg do you bench grind you own fly cutters?
[18:32:32] <CaptHindsight> you/your
[18:32:42] <toastyde1th> i certainly do
[18:32:46] <toastyde1th> others don't
[18:33:44] <toastyde1th> i also prefer bar-style chipbreakers rather than grinding the breaker into the tool itself
[18:33:59] <toastyde1th> longer life and easier sharpening over the long term
[18:34:36] <gregcnc> Turn a corner on the insert and go.
[18:37:00] <toastyde1th> on a production run, for sure
[19:11:56] <Sync_> they are not really meant for that toastyde1th
[19:12:08] <Sync_> they are for pulling out the insert instead of adjusting it
[19:14:49] <chupacabra> anyone have a 3040 chinese with 4th axis? I cant figure out where to plug the 4th axis in.
[19:15:27] <CaptHindsight> chupacabra: what motor controller and driver are you using?
[19:15:49] <chupacabra> LOL
[19:16:03] <CaptHindsight> the 3040's from China come with all sorts of combos
[19:16:05] <chupacabra> no clue. whatever it came with.
[19:16:18] <CaptHindsight> well then post pics
[19:16:25] <CaptHindsight> maybe we can help
[19:16:26] <toastyde1th> Sync_, we used to have a set of 12" diameter facemills with a whole host of position adjustments on it. i am not talking about the hold down for the insert.
[19:16:42] <chupacabra> the 4th axis has a lead to a connector but nothing from there to the control box
[19:17:30] <CaptHindsight> unless you can give us make and part number the next best thing to do is post pics of what is there
[19:18:11] <CaptHindsight> it's not the psychic help line :)
[19:18:17] <chupacabra> the box sayd T-D axis controller
[19:18:41] <CaptHindsight> sounds like we'd need pics
[19:19:01] <CaptHindsight> but I'm off, so post and wait for answers
[19:19:04] <Sync_> the answer probably is, you gotta disconnect another axis
[19:19:10] <CaptHindsight> lol
[19:19:25] <chupacabra> http://www.ebay.com/itm/New-CNC-Router-Engraver-Milling-Machine-Engraving-Drilling-4-Axis-3040-Desktop-/181675741198?ssPageName=ADME:X:RTQ:US:1123
[19:19:29] <CaptHindsight> 4 axis mill (3 active at any one time)
[19:20:05] <chupacabra> but there is no lead that will reach the 4th axis.
[19:20:28] <CaptHindsight> post pics of the control box
[19:20:34] <CaptHindsight> where the connectors are
[19:20:47] <chupacabra> post where?
[19:21:14] <CaptHindsight> imgur, imagebin.ca or similar
[19:22:23] <CaptHindsight> http://i.ebayimg.com/images/g/54QAAOSwe-FU8Ra2/s-l1600.jpg
[19:22:32] <CaptHindsight> ^^ from the ebay link
[19:22:40] <CaptHindsight> does yours look like this?
[19:23:03] <chupacabra> yes
[19:23:37] <CaptHindsight> the unmarked circular 4 pin connector "might" be the 4th axis
[19:24:03] <CaptHindsight> are you missing a cable for this?
[19:24:11] <chupacabra> that is what I figure but I have no cable from it to 4th axis.
[19:24:55] <chupacabra> I asked them but got nowhere.
[19:25:04] <CaptHindsight> sounds like they owe you a cable
[19:25:39] <chupacabra> they dont know what I'm trying to tell them. Waiting on a new reply now.
[19:25:40] <CaptHindsight> Item location: Ontario, California, United States
[19:25:57] <CaptHindsight> at least it's not China
[19:26:04] <CaptHindsight> anyway BBL
[19:26:10] <chupacabra> but they are chinese
[19:26:20] <chupacabra> thanks
[20:18:40] <Contract_Pilot> i noticed in the pcconf that the 5i25 folder is not there wonder if that is why it does not work?

[22:06:36] <Contract_Pilot> pccponf works on 2.7.3 not to do some more playing befor a busy weekend tomarrow.
[22:10:53] <Erant> gregcnc: 1. Yes, I have one of those. 3/8" Cobalt, designed for aluminum. 2. I have step&dir servo drives, something similar to this one: http://www.ebay.com/itm/Applied-Motion-Products-SV7-S-RE-Servo-Motor-Drive-Module-24-80VDC-7A-14A-/331611226220?hash=item4d3591c06c:g:2DIAAOSwHnFVr4CJ
[22:11:08] <Erant> I have the BLuDC4.
[22:11:32] <Erant> Tuning's easy as it has an oscilloscope display built into the tuning tool.
[22:14:29] <Erant> (As far as the end mills go, I have an ERP-1212)
[22:15:11] <Erant> I got the feeds from http://www.endmill.com/pages/training/Speed%20and%20Feed%20-%20Roughers.pdf
[22:34:23] <trentster> archivist: you around?
[22:42:07] <toastyde1th> anyone know a lot about oscilloscopes
[22:42:23] <toastyde1th> i have a question about old-ish versus new
[23:32:52] <trentster> Hi all - some help and advice on the validity of my assumptions in regards to VFD tuning for LinuxCNC - is the formulas I have here correct?
[23:32:53] <trentster> http://cl.ly/132H2W440t30
[23:49:45] <bobo__> toastydelth what is your question. old vers new scopes ?
[23:51:02] <toastyde1th> bobo__, i'm looking at scopes in general, and I've noticed that there are early 2000s scopes with the same specs as more moden scopes in the several thousand dollar range - color screen/analysis functions, 1+ ghz, 4-8 Gs/S, and the same amount of sample storage
[23:51:11] <toastyde1th> and i'm trying to figure out what the practical difference is between them
[23:51:44] <toastyde1th> if i get a $2500 used scope with a cal certificate vs say an $8000 brand new scope, if most of the major specifications on the front end are the same
[23:52:04] <toastyde1th> (this is all hypothetical and I'm trying to understand, i'm not about to pay 8k for a scope)
[23:52:27] <bobo__> early 2000 is not old to me
[23:52:45] <toastyde1th> well, "older", not "old" like an analog scope
[23:52:52] <bobo__> early 1960 is old
[23:53:27] <trentster> Does anyone have a few minutes to chat to me about PDM vs PWM in regards to VFD's ?
[23:54:10] <toastyde1th> even the scopes from 2000 seem to have displays driven directly by the front end and don't have much/any lag in the waveform
[23:55:19] <bobo__> not handled a new digital scope , but there have been big advances in digital to analog chips
[23:58:55] <bobo__> if you are into the Gig Hz range , i'am not of much help
