Abstract
Recently demand for 5-axis machine tools rises by the need of the complexity of the machining shape and the machining process integration. Furthermore, 5-axis machine tools come to be used for machining the dies, molds or the high-accuracy parts. As a result, further high-speed and high-accuracy control is requested for NC controller for 5-axis machine tools. In this study, the new NC control method for 5-axis machining is proposed. The proposed method is aimed at the smooth posture change of cutting tools by filtering to the angle change of rotary axis. The effectiveness of the proposed method was confirmed by the cutting test.
