5軸制御工作機械によるラジアスエンドミル創製面の切削痕形状制御に関する研究

抄録

There have been many reports dealing with the motion accuracy of a five-axis controlled machining center. However, there have been few reports dealing with a synchronous accuracy between the spindle rotation and the feed driving motion. In the present report, we propose a novel method to control the cutting trace shape on machined surface in radius end milling, focusing on high repeatability of period in a fixed cycle feed motion to keep a synchronous motion between the spindle rotation and the feed driving motion. Moreover, we attempt to estimate the quality of machined surface with a proposed method for radius end milling of hardened die steel. As a result, a proposed machining method is found to be effective to improve the machined surface quality for a finishing process.
