Abstract

This paper deals with different hypotheses regarding the resistance of deformable material that is subject to plastic strain. For analysing cutting processes, a new cutting layout with a single shear plane is proposed here to calculate the specific tangential forces. The specific tangential forces in the different shear zones were examined by experiment to verify one of the hypotheses in question. These analyses verified that the forces depend fundamentally on cutting parameters and cutting layouts. Hence, it is necessary to take account of a correlation between yield point and deformation temperature, when determining the mechanical properties of the cutting material during machining. It is suggested here to determine the mechanical properties from the conditions compensating the hardening and the softening of the cutting material.
