Hi;
I'm designing in Solidworks, generating tool paths in MasterCam and Posting to a Generic Fanuc Post MPFAN. I'm trying to increase the decimal precision of the Post Processor to avoid some rounding errors and also to increase the Max spindle speed to 40,000 RPM. Can anyone point me in the right direction?
Thanks

What version MC??? and if you're using X, is the post a converted post from a previous version?

It's Master Cam v9

By decimal precision, I assume you're talking about the calculated math. From the Mastercam main menu click Screen > Configure. I don't have my SIM key with me so this is by memory. On one of the tabs, you'll see an input for "nci" decimal places. Change this value to increase the number of places where it will read to and begin rounding from. Keep in mind, too far out and you could slow down your processing greatly.

For RPM, look in the post file for this:

max_speed : 10000 #Maximum spindle speed

Change it to:

max_speed : 40000 #Maximum spindle speed

And at the bottom, might as well change this:

103. Maximum spindle speed? 5000

to

103. Maximum spindle speed? 40000
