Abstract

This study is described the realization of the direct end milling process using an articulated robot that is the best ideal machining process for aluminum building materials. The most important characteristic of this process is using the small diameter of endmill and the high-speed spindle reduce a cutting force in order to improve the low stiffness of an articulated robot. However, the behavior of end milling with super-fast spindle speed for extruded aluminum alloys was still unclear. In this paper, in order to clear it, the basic cutting experiments and the structural analysis were done. Consequently, it was proved that the high frequency vibration proper to high-speed end milling had a close reration to the stiffness (natural frequency) of machine tools or workpieces, and great affected the cutting force and the cutting surface. On the other hand, it was confirmed that the articulated robot had few effect on the high frequency vibration of end milling because of low stiffness, and that the cutting force was 50∿70% down compared with the fluting machine. Therefore, it is thought that the direct end milling process using an articulated robot is effective for the improvement of high-speed end milling performance.
