Machining undercuts
Machining undercuts
(OP)
Can anyone help me figure out how to machine the undercut areas of this part in 7.0 or 7.5 with a 3-axis machine? In I-deas I would have used a T-slot cutter with a profile cut but in NX I can't get anything to hit the undercut regions.
Thanks, JohnK

undercutting" is toggled off. Also, "part safe clearance" determines how close the system will allow the shank to get to the part. If you can post your part with the tool you want to use I'm sure someone would attach an operation for you.

As for your struggles, surface area has to be worked. Projection vector is usually the issue.
The problem with surface contouring your feature is the sharp corner at the top of the undercut, requiring a special tool that NX probably wouldn't support for surface area. Speaking of which, I noticed both top and btm edges of feature are planar, even though the face is curved. It appears to me you could cut that with a custom form tool and use planar profile. Maybe you'd rather not hassle with that, but I think the sharp corner poses a problem.

Take a look at this.
