Hi Ron,

The stroboscopic effect showed the spinning cutter apparently frozen where
it was while cutting a flat so I'm sure the video interfered with showing
the actual operation of the rear cutter.

So you think the rear cutter is actually moving in and out rapidly? Way
back in a Model Engineer's Workshop article someone built a mechanism to
provide relief on hobs. It moved the X axis in and out on a cam IIRC. That
created a back relief smooth slope till the next cutting tooth.

I can see sync'ing up the cutter with the spindle so the cutter always
starts at the same spot for each flat. I'm just having trouble getting my
head around the geometry for cutting the flats.

I guess it's really motion in 5 axis (spindle X,Y and CutterHead X,Y)
combined to produce a straight line tangent to the Z axis?

I wonder if MACH3 can do this?
