REVISITED STRESS EVALUATION IN CONTACT ZONE UNDER CUTTING
Abstract
When evaluating a thermal state of the cutting zone, there is a need to define the thermal flow capacity on the tool contact areas which are determined by the tension magnitude. A review of the native and foreign research on the tension evaluation under cutting with account for the mechanical behaviour of the process materials, as well as the temperature, strain degree and rate is offered. Specialists in noncutting shaping have obtained experimental dependences that could be also used in machining — when the strain degree and rate can be calculated by the cutting theory formulae. The tension in the shear area can be determined indirectly — using the energy balance equation for the cutting process based on the experimental data on the cutting force components and corresponding speeds. As for the heat calculations, at first, analytic dependences defined on the base of the energy balance equation under cutting are recommended for the shear stress evaluation. Secondly, the dependences including relative shift value for the stress analysis should be used.
Supporting agencies: The research is done on RFFI grant no. 12-08-01328/13 “Development of the forecasting fundamentals for tribological and performance properties of hard-alloy cutting materials”.
