When you want a smooth rounded part made with a flat endmill using wrapping, you need radial moves.
2D pocket does most axial moves with leaves a pretty rough floor, but if you look a the floor with parallel moves (I used 2D contour with offset roughing passes) it much better. This would mean a really fast way to cut a nice looking pocket on a cilinder or fast cutting of a fillet on a 5 axis machine.
Please let me know if you like this idea.
