surfacing an undercut corner rad?

programming2C78B_0-1695996275015.png


Having a brain fart on this one, Friday issue. I can't get Ramp or spiral to work on it today. Can't share the file obviously.

I assumed this is where the old blend was used, but I need to add the .02 corner rads to these o-ring grooves. The keyway cutter has .015 rads on top and bottom

3D Contour and Steep and Shallow should both yield good solutions. Downside is that you don't get to use cutter comp..

I cant get any of those to work! 

Here's a very close example of what Im doing. It's actually a .01 rad, not .02 but that shouldn't matter in this case.

Well, I've been beating against a 3D Contour for a bit, trying to get it to machine ONLY those radii, and came up empty. So I resorted to something that I knew would work; Trim/Delete Passes:

Now, this IS an Extension item, so not everyone is going to choose to invest in that option. However, as a shop owner myself, it's my assessment that this one little portion of the Extension more than pays for/justifies the entrance fee. I've used Trim/Delete so many times in my shop, I've saved hundreds of hours of fiddling around with toolpath settings.

back at it. Funny enough, I can get it THIS close without any Edits, but the instant I lower the top height to model top -.05 (to trim off the top passes) it doesn't generate AT ALL. What am I missing there?
