Abstract
Issues related to the peculiarities of а contact between the wheel working surface and the workpiece in a flat face grinding with axial tilting of spindle were further developed. Basic attention is given to the contact area of a wheel and a workpiece because it largely determines the thermal stress in the grinding zone. The paper shows the determinative roles of the angle of a spindle axial tilting, the wheel diameter and the grinding depth. Based on the geometric computer modeling in the KOMPAS environment, empirical dependence of the contact area on the specified parameters is offered. That allows determining the reasonable angle of an axial tilting of spindle to ensure the allowable area and, consequently, the temperature level in the grinding zone.
