3D roughing on a circular surface.

[Vikingdane]

Back again with another question

 

I have this part with 3D circular surface, but after much trying and frustration, I cannot find a proper way to apply toolpaths. The toolpath keeps digging into the hole in the middle of the part.

 

How would you do it?

its doing what its supposed to do for a pocket. what are you trying to do?

That's my bad, woops!

I'm trying to apply a toolpath to the wave-like surface around the pocket. I just can't seem to find a solution by myself.

+1 pocket is doing what it is supposed to do. I added some depth of cuts and wrote a blend for the top. Are you asking how to ruff the top profile?

That's exactly what I'm trying to do

Unfortunately, I can't open MasterCam right now due to me being away from the network that is hosting my license.

 

EDIT: How did you create the surface you used as a drive for the blend? Also, how would you rough it out before finishing it? That is my main question.

Use your containment boundaries and check surfaces to control it. I was doing s similar part (circular 3D) and the tech showed me how to create a few circles in the places. I wanted to contain. Worked very well. also I checked all entities then just selected my few drive surfaces. That also worked.
