Математическая модель теплового процесса при шлифовании

Abstract

A new theoretical solution to determine the temperature of cutting and the depth of penetration of heat into the surface of the workpiece during grinding considering cutting adiabatic rods, the set of which represents conventionally the removable stock, with a grinding wheel is proposed. It is shown that with the passage of the handling time the cutting temperature increases continuously approaching asymptotically a certain value and the depth of penetration of heat into the surface of the workpiece at grinding takes a finite value depending on the thermal properties of the process, in contrast to the known theoretical solutions. Let the heat source move with constant speed along an adiabatic rod. This brings the design scheme of heating during grinding to the real conditions of a grinding process and allows to approach scientifically the analysis of the thermal stress of the grinding process and to choose the optimal treatment conditions, taking into account the restrictions on the temperature of cutting.
