Couple of things to check:
1. If you're using Manual Tools, it may not be using your tool info. On occasion, it seems to default to a .500" dia. Try a System Tool of your dia. to see if that's better. I don't know if Bobcad is addressing this yet.
2. Keep in mind that all outside sharp corners will have radii equal to your XYZ Allowance. So if it's a large allowance for roughing you will large radii.
Although everything should clean up in verify when you run the finish passes.
When cutting cavities, I translate/copy the parting line up .01" to allow stock for finish grind. I've found that's the best no matter what software or machine.
Good luck,
