Tool wear occurs in the ball end milling, and it increases with the cutting distance. It gives undesirable influences on the machining accuracy and that prevents high accuracy ball end milling. If necessary, the dimensional accuracy of parts has to be improved by a post process such as grinding. However, the post process lowers machining productivity, machining time becomes longer and machining cost becomes higher. The purpose of this research is to investigate the behavior of machining error due to tool wear during the ball end milling of inclined plane by a long time continuous cutting and to compensate the machining error. The compensation is carried out by increasing the depth of cut in NC program when the machining error reaches a threshold value. The validity of this compensation method is confirmed by experiments.
