3D Machining Strategy

[blackprogram]

Can anyone advise please regarding a 3D machining strategy for a fillet in the corner of a part. I used the Parallel strategy with a 4mm ball nose cutter but it leaves a unsmooth finish along the fillet, and I end up having to finish this by hand, I want the machine to do this for me, I am struggling to find a strategy. I will post a screen print with the fillet in blue along with the fusion file.

Hi

The parallel works good for the sloped face but isn't suitable for the fillet.

I've adjusted the Parallel path by giving it a Boundary, and setting tool center on boundary, this means it only machines the sloped face.

Then for the fillet I have used the Trace toolpath with the 4mm Ballnose to follow the fillet contour.

I select the top contour of the fillet, then set the compensation type to Left and give it a Negative axial offset of 2mm(the Ball Radius)

I've also included Flow and Blend toolpaths with the 8mm Bullnose as another alternative strategy.

Than you that is great.
