Abstract: A methodology and algorithm of optimal torns tool orientation control for 5-axis NC machining is presented. The contact condition between the cutter and sculptured surface is considered in global. The algorithm has simple mathematical model. The cutter location data is reasonable and precision. All of these can improve precision and efficiency of programming theoretically and practicality.
