Abstract
In this paper a method for predicting cutting forces is described. The model considers the indentation or ploughing effect and the presence of a parallel-groove type chip breaker. The technique is based on the measurement of the chip-breaker geometry and the calculation of the effective side-rake angle. The indentation effect, the dynamic shear stress and the cutting forces are determined from experimental studies. The proposed model is applied to the machining of martensitic stainless steels using coated carbide tools. Finally, the experimentally-measured cutting forces are compared with theoretically-predicted values.
