Hi guys,
Rich, from A18, your first two pics.
The tool tip radius is too large and/or the stock is not big enough at the large ball.
The remaining material there is not => the depth of the cut.
The tool path displayed represents the radius point of the tool tip (.016) which is why it shows so far from the profile with a Clearance set at .001
Either increase the stock dia., or reduce the tip radius and it does much better.
Here is the same file (I think) with a tip rad. of .005 Other settings are the same as yours.
I think this is what we saw some time back.
Please correct me if I'm wrong.........I'm used to it.
