2D Countour Faceting on Oval Part

[StephenBender]

I'm trying to cut the parts below on my HAAS VF2SS.  I'm getting facets in all of the curves while using the 2D Contour tool path.  I have tried numerous different tolerance and smoothing settings with the same faceting.  Any advice would be appreciated.  Thanks.

The issue is that a true oval cannot be described as a few arcs, so the total tolerance must allow for it. Tightening the Tolerance to .0002" and setting Smoothing to .0015" I get a toolpath of only 852 bytes made entirely of arcs (right click on the toolpath size and select View Toolpath to see this window):

Thanks.  I'll run that in the machine tomorrow and see how it turns out.
