I have a couple of nice Kennametal threadmill tools with replaceable inserts that the last engineer had ordered but I guess never got around to installing them. They're the style that come as a certain pitch but then I can threadmill whatever diameter I need. I contacted my Kennametal rep and he sent me the software to write the programs, however, the program outputs the units in millimeters.
I'm not a CNC programming whiz but in order to substitute our current production program's tap code to use this threadmill, I figure I use Kennametal's autogenerated program to become a subprogram whenever the time comes to tap. Since our production programs are in inches, can I G21 at the beginning of the subprogram and then G20 at the end before M99? I've never used those G codes before and am not 100% certain if that's the correct way to do this.
Thanks.
