The current implementation of non-indexed 4th axis in CAM is pretty limited:
--it only supports 2d adaptive, pocket & Contour
--it only works on a cylindrical surface.
I'd like to see Autodesk expand its capabilities, to allow the generation of 4th axis toolpaths for shapes that are non-cylindrical and/or asymmetric.
For example, I need to make a part that has a helix that spirals outward. That's a perfect application for a full 4 axis CAM toolpath.
I just checked out the current roadmap & there is no mention of any 4th axis improvements... 😞
