I am too far behind in terms of programming and being into CamBam API to try it myself. And there are already plugins which do almost what I have in mind but not completely. And ... there actually may exist a tool I have missed which does it.
Here is the idea: Using a tool with a spherical head (not ball nose but a sphere with a stem) to mill a sphere with a stem, i.e. go below the middle and do a spherical undercut as far as the tool geometry would allow. Both convex and concave spherical shapes. The reason for this is that I want to make a kind of ball joint.
Is it doable and anyone (Eddy I mean you Wink ) willing to give it a try?
Here is a small graphical representation.

Before asking a question do some effort and walk through all menus and options in CamBam.  Maybe the answer is there. Please.

Me too if I only had them Smiley
Your Profile2Helix plugin is almost there.

P.S. Even with a lathe and 4-th axis internal cavity would not be that easy IMHO.

I was playing with a vertical plugin for use with a large diameter winged cutter but the problems kept mounting up. Time is not good at the moment to revisit that.

Is CamBam Lathe no use ? I've never looked into it deeply enough to know.

We the profile2helix plugin all the time with a winged rounded edge cutter to cut flanges with a curved undercut much deeper than you show. A ball would be really easy. We draw the part profile, offset the line by the tool nose radius, then move that line over in X by the tool radius of winged cutter center line. Then generate the helix and use engrave.

I have tried with only a semi-circular profile and didn't get the desired result. But did not guess to make a profile like in Eddy's example. Will give it a try.

I tried to reproduce the profile from the picture by Eddy but got only the top hemisphere. The helix stops at the equator.
Are we talking about the same plugin?
