[00:03:08] <tjtr33> no, halcmd_commands.c reads and writes data to shared mem ( not rtapi )
[00:04:41] <tjtr33> and theres tools to lookup where in shmem the pins are like 'halpr_find_pin_by_name(name)'
[00:06:20] <tjtr33> so would i hack in a msg to a server inside halcmd_commands.c or would i monitor shmem changes and report to a server
[00:06:27] <tjtr33> (or some other thing i hadnt thought of )?
[02:07:53] <DJ9DJ> moin
[02:15:46] <RyanS> Is that like top'o'da mornin'?
[06:30:15] * Loetmichel is just editing some gcode to make a taper... http://www.cyrom.org/palbum/main.php?g2_itemId=14394 ... to make THAT http://www.cyrom.org/palbum/main.php?g2_itemId=14397 into THAT: http://www.cyrom.org/palbum/main.php?g2_itemId=14375
[06:31:19] <Loetmichel> ... that will be the MOST expensive motorcycle bulb EVER... 60 eur for leds and smps, a bit of 7075 aluminium and countless hours of machine time... ;-)
[06:31:59] <archivist> I have started todays long job....2.8 hours for one bevel gear
[06:32:29] <archivist> and restarted it after one axis decided to lose steps
[06:34:51] <Loetmichel> that is the second "billet" i am machining
[06:35:05] <Loetmichel> the first hat some step loss on one axis, also
[06:36:10] <archivist> in my case it went out of the cut so just add more balance weight reset home on that axis restart
[06:37:26] <Loetmichel> lucky you
[06:37:36] <Loetmichel> mine went INTO the cut :-(
[06:45:15] <Loetmichel> archivist: tht was the first try:
http://www.cyrom.org/palbum/main.php?g2_itemId=14400
[06:45:53] <archivist> oops
[06:46:31] <archivist> I am trying a new technique (to me) or generating a bevel gear
[06:52:43] <archivist> I can only swing the A axis 28 degrees one way before it hits the spindle housing too, so only generating over 56 degrees and only 24 steps, not sure how good the form will come out
[06:57:50] * Loetmichel crosses his fingers for archivist ;-)
[07:05:30] <archivist> just been and looked, just got to the halfway point at 0 degrees
[07:06:14] <archivist> having to manually drop some oil on the job at the moment
[07:12:59] * Loetmichel is just grinding down a 1/8" TC mill bit to 2mm shaft, so it can dive in 24mm instead of 6mm ;-)
[07:29:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14403 <- that looks fitting... and now: VERY CAREFUL milling ;-)
[07:30:11] <archivist> snap
[07:30:59] <Loetmichel> yes, can happen
[07:31:00] <archivist> bevel is at -11 deg ..... had sammich.... next coffee
[07:38:14] <jthornton> yikes, that is tiny
[07:39:12] <jthornton> anyone want to play with my tapping G code generator?
[07:45:43] <archivist> I haz coffee and bevel is at -16.33 deg pass...the excitement
[08:19:36] <Tom_itx> jthornton, if i could tap with my mill i would
[08:20:00] <jthornton> that would help
[08:24:05] <Tecan> http://i.imgur.com/l7YAqJy.jpg
[08:25:13] <Tom_itx> what a bargain
[08:26:08] <Tecan> fave stars
[08:28:51] <quitte> does running axis on a different pc than the backends work now?
[09:11:16] <archivist> some diagnosis required
http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1637.JPG
[09:14:23] <jthornton> it almost looks like a gear
[09:17:18] <archivist> not sure if it is the cutter being a few thou high and the fact I cannot get the full swing required
[09:18:28] <archivist> I need to make a longer cutter holder to get any more swing
http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1635.JPG
[09:21:49] <archivist> or the angle of the A for that particular count
[09:29:14] <Tecan> http://query.nytimes.com/gst/abstract.html?res=F30617FB3E5515738DDDA10894D1405B8485F0D3
[09:31:00] <archivist> largest! by what definition, I call foul
[09:39:19] <kwallace> Largest in 1894.
[09:43:40] <kwallace> archivist , what type of cutter are you using?
[09:44:10] <archivist> 40 degree cutter with straight sides
[09:44:46] <archivist> attempting the gleason method in gcode
[09:45:41] <archivist> trouble is there is still to much hand set up of where things are and angles
[09:46:04] <kwallace> I'll have to check out "gleason".
[09:47:04] <archivist> this should help
http://www.collection.archivist.info/archive/DJC/BK/BK2918/page_0087.jpg
[09:47:20] <archivist> rolling a cone over the cutter
[09:49:02] <archivist> which should be two cutters on taper paths, but I am hoping to get away with one and a rotation of the cone and a re run
[09:49:45] <archivist> I do have the cutter on its own 3 degree path
[09:50:44] <kwallace> How many passes per tooth?
[09:51:11] <archivist> I am doing 24
[09:53:58] <kwallace> Okay, thank you.
[09:55:47] <archivist> I think it is probably just not set up well enough, it is the sort of form one sees when hobbing spur gears and the hob is not at the right pcd
[10:11:59] <kwallace> Is there any reason to not use CSS with G76 (Threading)?
[10:48:46] <Tom_itx> archivist, it looks like a screw head recess tool
[10:52:38] <archivist> the cutter? , no it is a cutter I ground to straight sided form, better view top left
http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_11_07_Drive_gear/IMG_1400.JPG
[10:53:28] <Tom_itx> i know it's a gear but it looked like a recess tool
[10:55:30] <Tom_itx> what's it for?
[10:56:53] <archivist> some customer wants an odd ratio pair of bevel gears, been needing an excuse for a long time to develop the gcode for the method
[10:57:27] <archivist> and tiny .5 mod so 15 mm dia ish
[10:57:54] <archivist> it is for a tractor model
[11:01:58] <kwallace> "some customer wants an odd ratio pair of bevel gears" He must be 'some' customer to be able to afford to pay a fair price.
[11:02:25] <archivist> or me cheap enough to have a go
[11:05:28] <archivist> if I can get the technique right...profit because I can do any pair
[11:06:38] * Tom_itx gives archivist a 'gear maker' shingle to hang
[11:07:14] <Tom_itx> i've got all but a rotary head to try it
[11:07:36] <Tom_itx> i'm not sure what these cutters are for though
[11:07:48] <Tom_itx> i know some are slitting saws but a couple have profiles on them
[11:09:44] <archivist> just need the right angles for generation though, no need for fancy profiles
[11:10:56] <kwallace> It seems to me that one needs a cutter that can cut any rack profile, but also varies on-the-fly.
[11:12:09] <archivist> that is why on the gleason there are two cutters on taper paths
[11:12:47] <archivist> which could be one cutter and a rotation of the blank I think
[11:14:26] <kwallace> This seems like a good application for a wire EDM.
[11:15:44] <archivist> could be yes
[11:16:58] <archivist> kwallace, dunno if you saw me paste this in the other day
http://www.youtube.com/watch?v=15anXJ1y3PI double taper planer
[11:17:00] <Tecan> (15anXJ1y3PI) "Gleason w710A- cutting straight bevel gear- BSB Bozic" by "Savo Božić" is "Tech" - Length: 0:01:05
[11:21:01] <kwallace> Yes, I did. I suspect this machine uses hardware logic. Converting it to LinuxCNC could be great fun.
[11:23:14] <archivist> I had a quick look around for old ones but not seen any cheap/free
[11:27:45] <Tom_itx> i don't think my math is good enough to figure out the angles for that
[11:28:41] <Tom_itx> saw that video the other day
[11:28:46] <Tom_itx> pretty cool
[11:30:03] <archivist> some is just cones rolling around an axis, no maths needed
[11:31:03] <archivist> getting the axes in line with each other at a coincident point and on the cutter line...that is the "fun" part
[12:15:10] <IchGuckLive> hi all B)
[12:21:11] <Loetmichel> *Shi***Shi**... flown out of the chuck a few times when smoothing over in the lathe... anyways, will cool the LEDs, even with the dents. now i have to mount 9 leds @ 1,5W and the resistors and then the expensives LED 12V15W led bulb for motorcycles will be done. ;-) ->
http://www.cyrom.org/palbum/main.php?g2_itemId=14406
[12:47:14] <jesseg> I hate it when things fly out of the lathe.. Especially the chuck key. but never mind that.
[12:47:36] <archivist> duck
[12:47:46] <jesseg> LOL
[12:48:25] <archivist> the chuck coming unscrewed is a little disconcerting
[12:49:35] <archivist> me parting off sheet brass to leave a disk on an arbour makes people run for cover
[12:51:21] <archivist> boss would take 10-15minutes with a saw, I would take 30 secs and bits fly
[12:52:16] <AR_> removing the chuck key is like one of the top lathe safety rules
[12:54:03] <jesseg> AR_, oh? you mean it's not supposed to run with the key in? I wish I'd known that. I wouldn't have had to spend 3 days with the angle grinder making a slot in my ways. I thought it was a manufacturing flaw!
[12:54:29] <Loetmichel> hrhr
[12:54:45] <Loetmichel> archivist: its a problem of the small CP "lathe"
[12:55:02] <Loetmichel> the chuck isnt the best quality, like the rest of the lathe ;-)
[12:55:04] <Loetmichel> c0
[12:55:24] <archivist> it happened to me on a Shaublin...
[12:55:37] <archivist> best swiss
[12:56:10] <jesseg> AR_, hehe yeah I know.. I do my best. However if you know someone who's been a machinist for any length of time and never done one dumb thing then I want to take lessons from him :P
[12:56:25] <archivist> has a rather easy to use reverse switch and a 3 phase motor which cares little
[12:56:47] <Loetmichel> it seems i have hit the filament height pretty good, tough... ->
http://www.cyrom.org/palbum/main.php?g2_itemId=14409 ;-)
[12:56:49] <archivist> you learn from mistakes
[12:57:20] <jesseg> The way I see it, people are not machines. I don't care how good you are at something, if you do it enough times you'll mess up. Enough times might be 100, maybe 1000, maybe 100000 times. Sooner or later it'll happen. It's about 100 times for me :P
[12:57:24] <archivist> someone making no mistakes is making little/nothing
[12:58:11] <Loetmichel> archivist: this chinese pile of crap is my "lathe" ->
http://www.cyrom.org/palbum/main.php?g2_itemId=520
[12:58:47] <archivist> Loetmichel, what is it going to be when it grows up?
[12:58:59] <jesseg> LOL yeah. And the higher the cost of a mistake, the better one learns. Problem is, my lathe is a cheapo chinese Shop Master or whatever. The lathe spindle startup is so slow that the key just falls out when it turns to point down, and so far hasn't hurt anything. Same with mill spindle. (It's combo unit.)
[12:59:29] <Loetmichel> archivist: for size comparsion:
http://www.cyrom.org/palbum/main.php?g2_itemId=14058
[12:59:40] <Loetmichel> this thing is SMALL ;-)
[12:59:58] <PetefromTn> LOL I made that mistake once with my 12x36, it took me about five minutes to remove the chuck key from my garage door.... I learned something there but that does not mean I won't do it again..
[13:00:02] <archivist> mine is small
http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_09_10_Starturn_cnc_lathe/P1010035.JPG
[13:00:58] <PetefromTn> OOoh that is a cute little one.
[13:03:56] <jesseg> archivist, I've thought about building a "Holder" for my two chuck keys, with a microswitch for each key. If all the keys aren't in the holder, it wouldn't start. But I haven't done it yet.
[13:04:11] <jesseg> I wouldn't lose my keys that way either.
[13:04:19] <jesseg> Cya folks.
[13:04:34] <IchGuckLive> im also of bye for today
[13:05:48] <kwallace> Since we are showing baby lathe pictures:
http://www.wallacecompany.com/machine_shop/Craftsman_AA_109/Craftsman_109-15a.jpg
[13:06:40] <kwallace> For me, I was trained from the start to never ever leave a key in a chuck, ever.
[13:08:56] <jesseg> kwallace, how long have you been running the lathe at least twice a week, and has it ever happened? :P
[13:11:35] <jesseg> I think I've done the mill key once and the lathe key twice in about 10 years. But I only get a chance to do it around once a month.
[13:11:47] <jesseg> in any case I'm sure you're a better man than I
[13:13:48] <Loetmichel> kwallace: in my first appreniceship the only girl in class did the trick to forget a springloaded key in the chuck... machine started with 2400 rpm... key-> door of the master craftsman... on eye level...
[13:13:52] <Loetmichel> ;-)
[13:14:29] <Loetmichel> we had tried to reproduce that: no idea how she did that: it is impossible to get that key stuck in the chuck...
[13:14:39] <Loetmichel> the spring soves it out of the keyhole.
[13:14:48] <Loetmichel> shoves
[13:14:53] <archivist> effing spring loaded keys are unusable for delicate setting up
[13:16:12] <kwallace> jesseg: I wish you you wouldn't take it as I'm being better. I had training from my dad, then again in high-school shop, then during work, shop mates would jump on any malfeasance.
[13:21:09] <kwallace> Old fart speaking. In my day... proper procedure and style was a reflection of one's character and honor.
[13:21:16] <kwallace> Sorry about that.
[13:28:39] <Loetmichel> hrhr
[13:28:52] <Loetmichel> kwallace: remember: apprenticeship
[13:29:18] <Loetmichel> in a "school" for learning craftsman
[13:30:47] <Loetmichel> and we were "information technology electronicans", who had 2 weeks "quick intro" fot the lathe and 2 weeks "mill" and 2 weeks "welding"
[13:31:18] <Loetmichel> so the spring loaded keys were a good idea :-)
[13:36:35] <jesseg> kwallace, My paternal grandfather was actually a very fine machinist. Unfortunately he died of cancer before I was born, so I never got to meet him.
[13:37:18] <jesseg> But yes, I'm just learning it as a hobby. I really truly enjoy it. Having youtube does help :P
[13:37:41] <jesseg> Well gotta run. Bye
[13:37:45] <kwallace> Apprenticeships were gone by the time I was a kid, but I had a co-worker that worked for Zeiss during WWII and had plenty of interesting stories.
[13:37:58] <kwallace> Bye.
[13:39:23] <jesseg> I don't know how good of an apprentice I would have made.. I tend toward approaching issues logically based on current facts and conditions... And a lot of the apprenticeship type industries may have a bit of a "We've always done it this way" mentality.. Even when "This way" may factually not be the best.. ha ha. I make a much better hobiest.
[13:44:37] <Loetmichel> in germany its not the way the americans do it
[13:44:48] <Loetmichel> we have a "school" for craftsman
[13:45:06] <Loetmichel> 3-4 years learning
[13:45:26] <Loetmichel> usually 3 days a week at the company, 2 days at school
[13:45:45] <kwallace> "We've always done it this way" might be why we in the US don't make anything anymore. It would be nice to find a balance., but it always come down to cost.
[13:45:47] <Loetmichel> and you get a certificate that you have learned this job throughly
[13:48:38] <Loetmichel> i thik thats one of the reasons why germans are seen as good craftsman around the world (i hope so) ;-)
[13:53:41] <andypugh> I leave the chuck key in my lathe. Mainly as a rebellion :-)
[13:54:11] <AR_> ;p;
[13:54:14] <AR_> lol
[13:54:25] <andypugh> Because it is _my_ lathe and I know that LinuxCNC is interlocked on the chuck guard which won't close with the chuck in.
[13:55:16] <andypugh> I won't let the students get away with it in the Motor Club with the lathe there though, where that isn't true.
[13:59:34] <archivist> the most important step is that last look at the machine before you press the firing button, is everything set, tight, loose crap moved
[13:59:51] <kwallace> I had a very brief encounter with teaching shop. It was like pulling teeth, to get kids to use safety glasses. I decided, it wasn't worth the effort. Too bad... somebody might have learned something.
[14:00:20] <Loetmichel> http://de.webfail.com/4d3e0d65b87 <- harhar, thats a cup i HAVE to get... thats SO me in the morning :-)
[14:00:30] <AR_> you should have just let them get chips in their eyes
[14:01:01] <AR_> Loetmichel, that's me if it's a huge cup
[14:01:07] <AR_> coffee barely helps me anymore
[14:01:13] <andypugh> I never wear safety glasses. I don't claim that is good or sensible, but it is the case.
[14:01:27] <Loetmichel> andypugh: me too
[14:01:27] <AR_> i'll admit i dont at home
[14:01:29] <AR_> lol
[14:02:09] <AR_> unless i'm holding a dremel cutoff wheel right up at my face or grinding something that i need to watch closely
[14:02:13] <archivist> safety glasses are often too scratched/misty to use the machine safely
[14:02:15] <andypugh> I think I was dissuaded by them generally being approximately opaque. Scratchproof lenses have made that less of a problem now.
[14:02:25] <kwallace> I was amazed me how often our local schools get sued.
[14:03:35] <andypugh> I recall when they made scratch-resistant motorcycle helmet visors compulsory in the UK. There was an outcry as overnight the price of visors tripled. Then we relaised that they now lasted 5 years not 5 weeks...
[14:05:11] <Loetmichel> to an extent that MY apprentice shot this photo of me a while ago... "how NOT to do it" ->
http://www.cyrom.org/palbum/main.php?g2_itemId=12244
[14:05:33] <kwallace> ... especially since schools don't teach shop, science and very little phys ed.
[14:06:02] <Loetmichel> ... he DID hel me extinguishing the trashcan with alcohol soaked rugs beneath the workbench afterwards, though ;-)
[14:06:06] <Loetmichel> help
[14:08:33] <archivist> Loetmichel, similar but I took the picture of the boss
http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=4176&subject=13455
[14:09:05] <archivist> he has just been buffing brass for a few hours
[14:09:23] <Loetmichel> looks like me on the job :-)
[14:10:14] <andypugh> Ah, well, the buffers in Sheffield used to wrap themselves in brown paper for just that reason.
[14:10:25] <archivist> he thought it was such a nasty job he could not make workers do it :)
[14:11:10] <jdh> any suggestions for straightening a ballscrew? 950mm long, .65mm bow in it.
[14:11:36] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13525
[14:11:51] <archivist> just spring it into the job, probably will run ok
[14:11:54] <Loetmichel> ... grinding ferrite plates to size ;-)
[14:12:00] <andypugh> You might find a local motorcycle shop is able to do it. Straightening forks used to be a common repair.
[14:12:20] <andypugh> Is that 0.65mm or 0.65" ?
[14:12:38] <jdh> mm. If it were inch, I'd just toss it.
[14:13:21] <archivist> that is well in springing distance but maybe too much for high rpm
[14:14:00] <jdh> I made some temp mounts for it. It bounces the carriage around a bit. Could be the carriage adjustment is just bad too though.
[14:14:04] <archivist> I think my southbend screw is worse than that
[14:14:32] <Loetmichel> jdh: i am a bit rough with that stuff
[14:14:59] <archivist> the carriage should not be bounce able
[14:15:00] <andypugh> In theory you set it up on two V blocks under a press with a dial indicator. Then you (somehow) work out how far apart the V-blocks need to be to do the job, and press the middle down until the DTI reads right, then enough further to give it a set. And repeat.
[14:15:02] <Loetmichel> i would just get a big bench vise and 3 short prisms out of plastic
[14:15:10] <Loetmichel> and press it into shape
[14:15:58] <jdh> I've been trying the v-block thing. I've moved it 10x the distance and it just comes back to the same spot
[14:16:06] <Loetmichel> or moint it at the end points and use a crowbar with some rugs warapped around to pry it in shape
[14:16:12] <Loetmichel> mount
[14:17:09] <Loetmichel> so you didnt moved far enough above the elastic distance
[14:18:14] <jdh> yeah, it seems to be pretty resilient. I assume it was bent in shipping, but I can't get it to bend.
[14:18:18] <ReadError> https://dl.dropboxusercontent.com/u/25091878/Photo%20Aug%2011%2C%202%2058%2024%20PM.jpg
[14:18:24] <ReadError> the fruits of my cyclone filter so far ;)
[14:18:34] <ReadError> cant imagine how many times i would have had to clean the filter
[14:18:49] <archivist> if it is properly hardened and tempered it may break before it bends straight
[14:19:45] <Loetmichel> archivist: ballscrews are normally only hardened on the outside
[14:20:10] <Loetmichel> about 1mm in the core is soft
[14:20:14] <jdh> it's a cheap chinese screw. Doubt they did any more than minimum
[14:20:16] <archivist> so bending will crack the surface
[14:20:49] <andypugh> http://youtu.be/yhP2Bqk9uCI?t=6m45s
[14:20:51] <Tecan> (yhP2Bqk9uCI) "Straighten shafts with pull down press" by "Matt Maguire" is "Education" - Length: 0:11:45
[14:21:10] <Loetmichel> jdh: if its chinese chances are it wasnt bend in shippung but was produced wiht tha bend in it ;-)
[14:22:02] <archivist> that is what I think too, built in bend from the hardening process
[14:24:32] <jdh> could be. The last 3 I got from him were straight
[14:25:27] <jdh> nifty video. Don't have that hardware though.
[14:26:02] <jdh> we have a tube straightening machine at work. It twists the tube and it comes out straight.
[14:26:12] <andypugh> You can improvise. Possibly using a jack and a door frame.
[14:26:14] <archivist> the bend itself should be some clue to how it got there
[14:26:54] <jdh> it has a bow about 75% of the length, then another one about 45 degrees off near one end.
[14:27:10] <archivist> there is also stretching as a straightening technique
[14:28:01] <jdh> I'll go ahead and make the mount out of 0.5" 6061 and see how it springs.
[14:28:07] <archivist> may have to fiddle the scale factor after that :)

[14:30:10] <jdh> that looks like a small version of our tube straightener. it's pretty cool to watch it run
[14:50:02] <tjtr33> any opinions of LibreDWG library with InkScape to read DWG format?

[15:08:48] <jthornton> anyone do rigid tapping?
[15:09:05] <jthornton> I have a G code generator to spit out the code for that

[15:24:28] <kwallace> Soup to nuts on one screen. We have Drill and Tap on separate screens, but allow "Post to File" to append to an existing file.
[15:28:44] <kwallace> What? No Glade?
[15:35:23] <ReadError> dumb question, probably doesnt exist, is there any type of API or web interface that could show the status of a file being ran
[15:35:45] <ReadError> i start the stuff in the basement then go back upstairs, ive been using my phones timer
[15:35:49] <ReadError> i could use vnc i guess
[15:36:06] <ReadError> i dont want to thrash the box when cutting though
[15:49:24] <kwallace> ReadError: This comes to mind, but I don't see anything that can give you the job completion status.
http://www.linuxcnc.org/docs/html/common/python-interface.html
[15:51:21] <kwallace> You could open a terminal session on your CNC with a remote PC, then "halcmd show" to see HALpin status, but again, no job completion status.
[15:52:37] <ReadError> yea, i was thinking it could take the max velocity and gcode feedrate etc and calculate an estimated time till completion somehow
[15:53:04] <JT-Shop> that is already there
[15:53:36] <JT-Shop> http://www.linuxcnc.org/docs/html/gui/axis.html#_menu_items
[15:54:05] <JT-Shop> or watch halui.program.is-running

[17:19:41] <Tom_itx> jthornton, seems you're the only one doing rigid tapping
[17:22:21] <Tom_itx> that's quite a setup screen
[17:37:52] <Mikeggg> jthorton: That's pretty slick. I'm setup for rigid tapping. have to give it a shot
[17:56:37] <Tom_itx> i wish i was
[18:08:42] <andypugh> Jon Elson does drilling and rigid tapping with a drill-tap tool.
[18:09:40] <Tom_itx> yeah that was pretty cool

[20:34:54] <NickParker> Today I discovered my mill is ungrounded. I took my sister to play with it barefoot, which was the first time I've done that because metal shavings. I touched one corner and felt something a lot like mains power. turns out it has a ground fault somewhere, which would explain my GFCI problems when i ground the 3 phase converter its spindle runs on.
[20:35:14] <jdh> cool.
[20:36:25] <jdh> I found a nifty kenametal indexable boring bar that came with my lathe and a bunch of carbide inserts. Turns out it is left hand though.
[20:41:54] <toastydeath> most boring bars for cnc lathes are
[20:59:05] <jdh> toastydeath: really? why is that? (it came with a manual mill)
[20:59:17] <toastydeath> on a cnc lathe everything's flipped upside down
[20:59:27] <toastydeath> so the tool is mounted upside down for right-handed tooling
[20:59:37] <toastydeath> you can't see a right handed boring bar IN the bore this way
[20:59:54] <toastydeath> so most of the bars are left handed so that you can see them
[21:00:29] <jdh> and run the spindle 'backwards'?
[21:01:46] <toastydeath> yup
[21:02:46] <jdh> just so you can see it?
[21:03:16] <toastydeath> sure
[21:03:28] <toastydeath> on a cnc lathe the spindle direction is as simple as m3/m4
[21:03:36] <toastydeath> nobody cares too much which way it's going
[21:03:41] <jdh> on a real one perhaps
[22:07:23] <Valen> what do you guys use to generate gcode for lathe work?
[22:08:38] <Tom_itx> jt uses those halpcv bits that come with 2.5
[22:08:47] <Tom_itx> i made a post for my cad cam
[22:09:02] <Tom_itx> lathes are pretty easy to code for
[22:09:16] <Jymmm> http://www.cbsnews.com/video/watch/?id=50152765n
[22:09:39] <Tom_itx> but i don't have a cnc lathe so the cam doesn't get used alot
[22:10:03] <Tom_itx> i fixed one up for andy a while back
[22:12:55] <Valen> I could probably make one, but I'd really rather not
[22:13:26] <jdh> make what?
[22:15:57] <Valen> cam for lathe
[22:16:26] <Tom_itx> lathe is simple enough you really don't need it
[22:16:46] <Valen> so you write compound curve g code by hand?
[22:17:02] <Tom_itx> no
[22:17:11] <Tom_itx> i have cad cam for that
[22:17:28] <Valen> right, and what do you use for lathe?
[22:17:28] <Tom_itx> but alot of it is simple cuts
[22:17:33] <Tom_itx> smartcam
[22:17:46] <Tom_itx> but i've had it for years
[22:18:43] <Valen> what sort of $ is it?
[22:18:55] <Tom_itx> back then i gave around 6k
[22:19:01] <Valen> spendy
[22:19:12] <Valen> cheaper than mastercam at least lol
[22:19:20] <Tom_itx> for freeform 3d mill and basic lathe
[22:19:30] <Tom_itx> it was better than mastercam at the time
[22:19:34] <Tom_itx> i looked at both
[22:19:38] <Tom_itx> as well as surfcam
[22:20:01] <Valen> mastercam seems to want you to basically do the drawing in it
[22:20:18] <Tom_itx> well so does smartcam but it will import models as well
[22:20:47] <Tom_itx> dxf or iges mostly
[22:33:04] <Valen> we use rhinocam which is built into our cad package which i normally nice
[22:33:31] <Valen> heh I wonder about faking it, give it a 1mm wide bit of stock and a 5mm tool
[22:33:35] <Tom_itx> yeah i've heard of rhino
[22:33:48] <Valen> tell it to do all its stuff on Z axis milling ;->
[22:33:51] <Tom_itx> you'd have to change your axis around probably
[22:34:23] <Tom_itx> i had to import a model from andy using my mill package and my axis were backwards when i went to use the model in my lathe package
[22:34:41] <Tom_itx> wasn't ideal but it did work
[22:35:20] <Tom_itx> everyone said you can't use a solid model for a 2d part :D
[22:35:44] <Tom_itx> i just peeled the profile off it and used ti
[22:35:45] <Tom_itx> it*
[22:37:38] <Tom_itx> and i was having trouble importing the 2d model for some reason
[22:45:57] <cmorley> Tom_itx: what version of smartcam do you have?
[22:47:56] <cmorley> I have version 7.55 run inside DOS
[22:59:57] <Tom_itx> i had a dos version as well but this is windows
[23:00:04] <Tom_itx> i forget the ver but it's older
[23:00:11] <Tom_itx> both still work
[23:00:50] <Tom_itx> the dos ver was 2.5d, windows is freeform with the basic lathe
[23:01:48] <Tom_itx> i'd have to boot the other pcs to find out
[23:13:54] <cmorley> hmm I'd like to collect more smartcam programs - I's like to find advanced turning. It appears soon after 7.5 they went to windows and then the dongle i have might not work.
[23:15:15] <cmorley> darn program was $10,000 bought new in 92....
[23:16:11] <cmorley> milling program would be interesting too...
[23:17:27] <cmorley> So old I can't find copies on the net :)
