Hey, so I got a problem. I have a profile I want to 4th axis mill, shaped kinda like a tapered cone. Something like the black spike in this image:

So if I start with a solid barstock blank, mastercam wants to plunge full depth and do the whole cut at once. I want it to take off nibbles. Should I just manually programing my own rough passes, or is there an option for multiple passes to final diameter on 4th axis contour parts? thanks!
