Select the tool type according to the shape of the machined profile

For concave surface, in semi finishing and finishing, the ball head cutter should be selected to obtain good surface quality, but in rough machining, the flat end end end milling cutter or round end milling cutter should be selected, because the cutting conditions of the ball head cutter are poor; for convex surface, the flat end milling cutter or round end milling cutter is generally selected in rough machining, but the round end milling cutter should be selected in finish machining, because of the circle The geometric condition of angle milling cutter is better than that of flat end milling cutter; for the side with demoulding inclination, taper milling cutter should be selected. Although the bevel can be processed by interpolation with flat end milling cutter, the machining path will be longer and the machining efficiency will be affected, and the tool wear will be increased and the machining accuracy will be affected.
