Poor verification from solids toolpath

[RMagnusson]

I've tried running some toolpaths on my newly created solid part model, but only with limited success.

 

The part looks like a long double-d shaped pan (rectangle but with the short Y-axis ends rounded) with several bosses sticking up from the base.

 

After reading Go Navy's post 'tool paths on solids' I used the method: create curves on all edges- toolpaths-contour- and selected the inner vertical face of the pan by chaining its lower-most geometry.

 

The toolpath looks perfect. It even follows the tight S shaped contours at either end.

 

When I verify the long straight walls come out clean, but any curved contour only gets cut every 20 degrees for about 5 degrees. Like the cutter is skipping when cutting the inside radii of the pan wall contours.

 

I am using a .250 flat endmill and the smallest thing that need be cut is a .5 DIA arc that travels 180 deg.

 

Is this when I need to use an stl to verify? Am I chaining my geometry incorrectly? Should I not use the create curve function?

 

Its probably something mind numbingly simple that will (hopefully) come to me when I wake up in the morning....but if not,

 

Thanks for reading folks.

Awesome, I'll give that a try.

 

Thanks.

That made a huge difference.

 

Thanks again.
