Re: [CAD_CAM_EDM_DRO] Re: True 4th Axis milling

about the #2 method in Vector
could that cut say a 'J' shaped cam grove onto a cylinder using
a cutter with a diameter smaller than the grove width and still keep the
sidewalls of the grove parallel?

we got a job like that not long ago and tried farming out the programing
to the local cam reps (Mastercam or Surfcam I think)
they couldnt manage to program the tool diameter offsets in the Y-axis
to keep the walls straight using a smaller tool (came out with tapered walls)
and we ended up having to use a full size cutter and take the full width at
once and live with the usual chatter and poor finish that gave
