Rotary finish on Carmen - Problem with "tool collision"

[Propellerhead]

I already posted this on another Forum without any results, so sorry for the "double post"

I should've gone here first I guess.

 

Im trying to create some roughing and finish toolpath simulations for carmen.

2 indexed roughing paths and a rotary finish pass.

 

The problem is that when the path reaches the feet, mastercam wants to mill the whole circumference of each leg. And this automatically saws off the other leg. (Pic attached)

 

When trying to select only the upper part of the body for rotary and trying to mill the rest with normal indexed surface finish (There is no containment option) I can't select a clear endling line because the surfaces are scattered and mastercam decides to mill inside the body at the edge, thus cutting away the whole body.

 

Could anybody help me here?

Can you share the model as the path is trying to keep the tool perpendicular to the surface at all times and running into the other side. you might wan to use a 5axis option output to a 4th.

Well I know that you can get a better finish by using Surface Finish>Parallel (what I usually do) and then when you have your speeds and feeds done along with your tool, change your stepover and when it comes to the machining angle, go 45 one way and go -45 to get an even better finish(faster feed). Don't forget to change your Stepover on gap settings! Hopefully this helps.~
