I’m modeling a simple circle with a slanted edge…granted it’s large, but I’m looking at the roughing time and it just seems excessive. It looks like the strategy for roughing is linear - moving across the center of the circle doing nothing on every pass - where a circular cut would be far more efficient. Is there any chance I’m missing something here? Is there any thought to optimizing this kind of thing? Following a vector, perhaps?
You can limit the 3D toolpaths to just the 3D geometry. Offset the larger circle (bottom of part) by half the tool dia. Select that circle & the smaller circle (top of part outside edge), and use that as your boundary for the 3D path. I would only rough, with a large stepover (cutter dia), and 50% DOC, 0 stock.
You’re going to sand it, so skip the finish path.
THis should get it down to < 30 min.
For giggles, I programmed a Z-Level profile cut in NX. 5 minutes

yes…that did the trick. In cc i just selected only the outer rings and it came down to 34 mins for the rough cut and 13 for the finish. That’s reasonable.
thanks!
