I've recently started playing more with a 4th axis and have Fusion spitting out some reasonably decent G93'd code.

Two things have come up now that I'm running a part or two.

1) Am I correct in assuming that the G64 P/q settings have limited/no effect when using the a rotary axis and linear simultaneously? I can't see a different in speed when I play with reasonable values for P.

2) Is there a minimum value for G93 feed rates. It would have been convenient at one point today to plunge an endmill into a continuously rotating A axis with something like G93 A45000 Z-1 F.2. Which I'd expect to create an inverse time of 1/.2 = 5 minutes to plunge the endmill 1" over (45000/360)=125 rotations @ 25rpm. A shallow cut in a narrow slot with a smallish endmill. But the feed rate that I got was much higher than expected, nothing below an F of .5 really seems to give me an output that I'd expect. Am I missing something? Is there a minimum/maximum value for F in G93?

Thanks
-Dave
