You don't have many options using the 10mm ball mill besides trace. If you used a smaller end mill, say 5 mm you could do a 3d adaptive to clear the bulk of the material and then 3d finish with ball mill. A lot slower for sure. Generally, when I mill a slot like this I'll ramp down into it with a flat end mill and then finish the bottom with the ball mill. I sometimes relieve the middle with a smaller end mill.

 

Design for manufacturabilty, you may find a flat bottom to work equally well for your application and will save machine time and tooling. If you need it radiused, than it may be possible to only go to partial depth, similar to a bearing race. Easy to machine and still effective. Food for thought. I don't know your application, just throwing out ideas. :winking_face:
