Re: Help - G-Code Circular Motion for CNC Milling
That helps a lot. Now how do I do this while moving downward? I don't want to take a 1/4" cut all at once of course. I could put like a G01 Z-.03 before the G02 code and then a G01 Z-.06 after and so on and so forth. Or is there a better way to do this? I know with G01 if you put like X1 Y1 Z-.5 it will ramp down until the Z axis reaches final depth of -.5 at X1 Y1. Is there a way to put G01 and G02 in the same line so the circle will like spiral down?

Mainly, I could just move the Z axis down a bit after running in a circle and then repeat but I think doing that would not make for a very nice bearing bore.

Any ideas?
