https://forums.autodesk.com/t5/machining-discussions-forum/spherical-3d-pocket/m-p/6083995#M5907 I'm trying to mill a spherical pocket.&nbsp; First step I'm using 3D adaptive clearing with a 1/4" flat end mill.&nbsp; Second step is a finishing pass and I'm using a scallop operation with 1/8" ball end mill&nbsp; In the 1/4" end mill operation I set stock to leave as 0.01".&nbsp; But when I go in with the scallop operation, there's a lot more then 0.01", it's closer to 1/8"<BR /><BR />Attached is my Fusion 360.&nbsp; There are two spherical pockets, I've only tried milling the large one.&nbsp; I assume the small one will have the same issue.
