高精度ボールエンドミル加工のための幾何学的評価指標の提案

抄録

The ball end mill is used as a tool for cutting the metal mold. The demand for the precise machining of the ball end milling is increasing. Previous studies clarified that machining error have the correlation with geometrical interference quantity calculated by the geometric analysis of ball end milling at any tool position. The purpose of this study is to propose a method of calculating tthe machining error estimation index for the complex shape machning, and some experimental results are shown.
