3d Contour from surface

[Mcam Nut]

Ok, I am kinda stumped. On a part I am working on Pencil finish isnt working out that well, what I am trying to do is have a normal 3d contour toolpath with a ballnose that the "Z" is controlled by a surface, not a chain. I want to ghave cutter comp on, and have the tool finish the entire wall with out gougind like a normal 3D contour. is this possible, or is pencil my only option?

How about a Surface Project toolpath?

Steve, I havent really tried using that path alot, can I use dia comp with that? I will try that see if it works, thanks

No dia comp in surf finish project

 

I'd use Curve5ax. Comp to surface, Drive a chain, use a line to control tool-axis

 

Assuming you are doing a 3-axis toolpath
