This entire thread has been very interesting to me. I've learned a lot about arc moves and creating spirals, but I'm curious why the large number of short G1 moves (generated by PathPilot) is "better" than fewer G2/G3 moves? Seems like a nearly constant feedrate/chipload (similar to adaptive clearing) would be better than thousands of start/stops/accel/decel - what am I missing?

I decided to see what Tormach generates with their conversational programming in PathPilot (LinuxCNC pretty face). I don't recall the original parameters so I requested a circular pocket, 0.5 deep, 1.0 diameter, at 0,0, 0.5 DoC, 1/4-inch cutter (what was in the spindle). It spirals down in a 1/2 pocket to full depth and then does a spiral out. I'm happy to try different parameters. (Mill - Circular Pocket G-code generated: Tue Sep 24 16:36:41 2019 )
