Hi General.. What you are showing there is "pocketing".. The term profiling was confusing me.. The profiling is a toolpath that will follow an exact contour (and step in on it)
I dont see "air" in the normal pocket:
Although, as you state, the newer HSP technology, will "Morph" the pocket toolpath to make it more efficient:
The regular pocket routines keep the toolpaths contours as defined by the pockets geometry. The HSP one will recognize pockets within the pocket and create toolpath that morphs and is more efficient..
