切削シミュレータを用いたびびり振動抑制工具経路生成方法の開発

This study proposes a new method of tool path generation with suppressing chatter vibration. To achieve the objective, a new cutting simulator has been developed in this study previously. The simulator is developed based on the Vatti clipping algorithm that can realize high speed and high accuracy, and can calculate chatter stability diagrams of each cutting point successively owing to its high speed property. Therefore, the tool path without chatter can be generated by tracing points in the stable region. In this paper, details of the generation algorithm of the tool path without chatter using the cutting simulator is presented. And the effectiveness is confirmed by pocket machining with a square endmill by comparing with the conventional tool path.
