I have a question about doing a Surface Contour Finish on a .250 diameter chamfer. I have tried several tool paths but the chamfer is being cut on the inside of the pocket. The model I'm working with has a arc going counter-clockwise. When I verify the cut, it's milling it clockwise. The tool I'm using is a 1/8" ball end mill. In cut depths, I selected the top of the arc +.03 and the bottom of the arc. I'm still new to MasterCam. Any help is appreciated. assignment2.bmp
