THEORETICAL AND EXPERIMENTAL INVESTIGATIONS PROCESS STOCK REMOVAL, WHEEL WEAR, FORMING ACCURACY AND THERMAL VOLTAGE AT GRINDING OF CYLINDRICAL AND STEPPED SHAFTS WITH CROSSED AXES OF PART AND WHEEL
Practical application of new grinding methods of high-performance cylindrical and stepped shafts requires their theoretical and experimental research on the basic machining parameters: grinding performance, the wear rate of tool and thermal stress. Accounting thermal stress process in theoretical calculations is carried out through coefficient, which with increase of the heating temperature considering change of physico-mechanical properties of the processed material. In order to ensure the maximum performance of grinding the planning of full factorial experiment with three factors (longitudinal feed per revolution and the speed of detail and the angle of the tool orientation) carried out and the significance of the regression coefficients tested.
