    How Do You Get The Cutting Parameters Right For Small End

    Jul 24, 2009 Do you concentrate on the sfm for finish end mills of the same diameter, or do you consider that the center of the ball is going to push harder for a given feed per tooth? Then, when lace cutting, the stepover becomes my next challenge. When I do feel confident with my feed and speed, I am unsure of my stepover or depth of cut

    The roughing process was performed using high-feed milling, characterized for the very high feed per tooth of 1.2 mm/z and the small axial depth of cut. The main advantage of this milling type was that no big stairs were produced in roughing, so the semi-finishing operation was eliminated
