Calculation of Thermodynamic Parameters of Geometrically Complex Parts at Abrasive Globoid Gear Machining

Globoid gear honing made by abrasive tool has such special features as considerable length of the line of contact, profile contact along several toothed surfaces simultaneously, dependence of the stressed-deformed state in the work area on machining conditions, and characteristics of an abrasive layer. All these facts lead to the considerable modification of thermodynamic parameters in the work area. Tool setting accuracy relative to the component part influences greatly the character of these modifications. This paper is devoted to the development of a thermodynamic mathematical model and determination of basic laws of thermodynamic parameters formation in the process of abrasive globoid honing of geometrically complex toothed surfaces. The temperature in the work area, the distribution of temperatures along the line of contact, and change of temperatures depending on the parameters of globoid tool setting could be defined by this model. Numerical experiments have been carried out on the basis of the proposed model. The results have been represented as a diagram.
