Title: Mastercam X Lathe Post Processor
Post by: davidimurray on February 07, 2007, 03:30:03 AM

Has anyone used Chris Krstanovics V9 post processor in mastercam X. Its behaving very oddly as for roughing work it is fine, however when I put a finish path in, all the arcs are in the wrong direction (but not in the roughing pass!!!). Anyone else had this problem or got a post that wrosk?

Cheers

Dave

Thanks for the offer Graham.

I've been having a play and it would seem like the standard Fanuc 2X PP seems to work pretty well. The only funny problem I have had is that it set G97 on one line and then a few lines later in front of the first move it puts G98, even though all operations are set to RPM and mm/min settings. If I delete the G98 the part meachines fine. Not a big problem but it would be nice to get rid of it.

Any ideas?

Cheers

Dave

Some posts do a G97 to stop the spindle accelerating as the x axis rapids into position and then change to the G96 to do the cutting, sometimes they do it on a rapid to a tool change as well.  The G97 fixes the speed at what ever it is at the time.

Send me the post and I will sort it for you.

Graham.
