4th axis tool path depth cuts?

[clivefx]

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!

Hi Clivefx,

Did you ever figure out a way to do this? I've been wondering the same thing for a few weeks now!

If I remember correctly it depends were your z0 is, you adjust that in your tool profile on how deep to cut. I had the same problem on one 4th axis job and it took me a very long time to figure it out( I ended up offsetting it in the machine). once I figured it out it was stupidly easy. that was a long while ago and cant remember exactly what I did.

I also am curious about how to do this.
