Final and element modeling of workpiece temperature at the combined grinding

Abstract

Abstract The combined grinding is characterized by simultaneous preliminary and final machining of workpiece on one machine tool without replacement a coarse-grained on a fine-grained grinding wheel, that allows to reduce the main and auxiliary time for performance of technological operation, and, therefore, to increase grinding process productivity. Entry and boundary conditions of computer modeling of the maximum temperature of the processed surface at the combined and traditional grinding are defined. Modeling of surface temperature is carried out in the modern Solid Works software product for simultaneous grinding by wheels with various characteristic of abrasive material, what in scientific-technical literature was not considered earlier. Models of the maximum temperature of the processed surface in a function of removed overmeasure, longitudinal and cross-feed of workpiece, on the basis of which the cutting regime of the combined flat peripheral grinding, providing elimination of thermal damage of the processed blanket, is appointed are established.
