Simulation of thermal strength of the process of flat grinding of workpieces in intermittent circles

Abstract

The present article is concerned with numerical schemes of the radial Py and the tangential Pz components of the grinding pressure and with the average contact temperature T, °С. These characteristics give an opportunity to assess the level of the thermal power strain at every path of the operational cycle of the flat pendulum grinding using a standard grinding wheel (SW), an intermittent grinding wheel (IGW) and a composite grinding wheel (CGW). Value forecasting of forces Py,pz and the temperature T will make it possible to manage the grinding process and will give the opportunity to avoid the defects precipitation at the grinding finish of the workpiece.
