General Mach Discussion / Re: z axis losing position and plows into fixture...help

« on: January 27, 2009, 07:35:04 AM »

Jim,

thanks for looking at this...  the code is supposed to plunge into the material (material is gone from previous cut) and then do a line move and then arc into the cut.  the cut is a circle that is 1.215 diameter and it is being made with a .370 end mill.  its supposed to rough the circle at a .250 depth and then rough at .500 and then .525 then do a finish pass at .525 depth at a larger diameter taking out the last .010 of material.

General Mach Discussion / z axis losing position and plows into fixture...help

« on: January 26, 2009, 09:27:11 PM »

i made most of the fixture this morning and everything worked just fine.  i was able to rough at various levels and came back to do a finish pass and the part came out great but a little small on the diameter.  so i decided to create a finishing cycle with my cam program (onecnc btw) and here is the code it spit out.  as far as i can tell the code is fine.  for some reason it will do the first rough at .250 deep, which is correct.  then it decides to plow into the material at the bottom of the hole to .800 deep.  well this just ruined the first hole in the fixture.  when i back the tool up and out and retouch it off, the tool is .300 lower than expected.  ok, no problem maybe the touch off was off, then i went and ran the first hole again.  it again wanted to plow to .800 deep.  pulled it out and retouched off the tool again...again .300 low.  rehomed the machine and retouched off the tool.  now its .600 high and retouched off to the exact first number i ahd before to within .0002. 

any idea whats going on here?  i find it strange that it ran everything else just fine and the first set of programs i ran on it.

So based on the corrections listed...ultimately i'm not worried about the geometry corrections of the hex.  i just want the rest of it to work.

General Mach Discussion / nesting sub programs

« on: January 11, 2009, 10:11:09 AM »

can mach 3 nest sub programs?  basically i want to run one sub within another sub to give me two rows of parts.  ideally i would like to make one hex, then move over complete nine more. then move up a row and repeat the pattern of 10.  i'm thinking that i would want the center of each hex to be zero then use and incremental move code to do the hex.  does this make sense?  the code i've posted below will allow me to do one hex but won't step over to do any others.  i'm thinking that i have something wrong in my coding.  yes i realize i can do this in lazy cam but i don't want to be dependent on that, plus i want to use the wear offsets available in cutter comp.

here is what i have so far...

Feature Requests / wear offsets

« on: January 07, 2009, 11:18:11 PM »

i would like to see wear offsets implemented in both lathe and mill.  i think this would be a great asset when machining harder metals that tend to wear cutters like stainless steel or titanium.

LazyCam (Beta) / Re: need help creating code with L cam

« on: December 22, 2008, 11:16:58 PM »

Rich i will try that in the morning.  also what does the overhang do?  its funny but no matter what i did when i moved the start point it would either pocket half or not pocket at all.  i was trying to do the pocket with a 3/8" cutter though.  this plate that i'm cutting is 1/2"thich 304 ss.  so it should be alot of fun.

LazyCam (Beta) / need help creating code with L cam

« on: December 22, 2008, 03:12:35 PM »

i am trying to cut a bunch of flanges with my mill and i'd like to generate the program using LCam.  i can get the pocket function to work on circles however  i have some slots with round ends in the flange as well and it won't pocket these.  i have attached the DXF i'm using.  when i move the start point of the pocket it will pocket some of it, but it will never get all of it.  i can do two seperate halves but not one complete pocket.  the interconnection points on the cad program are set to 1e^-5 and the setting for loading on lcam are set to .01.  i tried .001 and .005 to no avail.  any help is greatly appreciated.
