A revised instantaneous rigid force model for end-milling operation to eliminate predetermination of cutting coefficients

抄録

The purpose of this study is to propose a revised instantaneous rigid force model based on oblique cutting model for end-milling operation to eliminate predetermination of cutting coefficients. Although, six cutting coefficients are required for cutting force prediction in the conventional instantaneous rigid force model, the shear angle is only required in our revised force model. The determination of the shear angle is easier than the determination of six cutting coefficients from the cutting test. As a result from a validation, our revised force model can predict the cutting force more practically than the conventional instantaneous rigid force model.
