Tool radius compensation for Mach3 DONE
« on: September 15, 2009, 01:48:05 PM »

Recently I got a job for making a very special lathe for a client. I did it with Mach3. But my client uses existent FANUC machine code that already have the tool radius compensation. No CAM was allowed in between. I had two choices:
1) Quit the job
2) Make an application that "translates" non compensated code to compensated code and Mxx and G72 G74 among others instructions fully compatible with mach3

I did the program and the machine. This software is working every day.
I do not know if there is interest for users or for even Mach personal. If a good number of users have interest, I can make a sample version cropped in some manner to test.

Where goes a sample of a translation (G72 and others macros were calculated to simple movements. Also the tool compensation was taken in account):
