傾斜切削理論に基づくエンドミル加工の切削力予測モデルの提案

抄録

Instantaneous cutting force model is widely used for the cutting force prediction for end milling operation. However this model is required to prepare 6 parameters called cutting coefficients which can be determined from experimentally measured cutting forces. In this study, a new end-milling force prediction method based on oblique cutting model is proposed. This method can predict cutting force using only the experimentally predetermined shear angle instead of 6 cutting coefficients required for a conventional instantaneous cutting force model. This method is easier to apply for practical cutting force prediction, because it is easier to predetermine shear angle than 6 cutting coefficients.
