摘      要：Cutting forces with respect to different cutter orientations are analyzed for five-axis NC machining of a ball-end cutter.A measure is then defined to quantify the effects of cutter orientation *** to the measure,a novel model and algorithm are proposed to wholly optimize cutter orientations based on a cutter contact(CC) point *** method has two *** is that the cutter orientation smoothnesses along the feed direction and pick-feed direction are both wholly *** other is that only the accessibility cones of mesh points are required to compute and the computation efficiency is *** advantages are shown by simulating the machining efficiency,the stability of feed velocities and the smoothness of cutting force.A computational example and a cutting experiment are finally given to illustrate the validity of the proposed method.
