A new end-milling force prediction method based on oblique cutting model

Abstract

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.
