Calculation of Surface Hardness when Surface Grinding ASIS 1045 Steel

Abstract

This study presents a prediction study of the surface hardness in surface grinding ASIS 1045 steel. Base on the experimental data on the changes in characteristics of steel in the heat treatment processes, the relationship between the surface hardness and the impacted temperature in surface was found. Besides, the relationship between the cutting temperature and the technology parameters in the grinding was created. The surface hardness was then formulated as a function of the technology parameters in the grinding processes such as the depth of cut, the grinding wheel speed, the workpiece speed, etc. The proposed model was verified by comparing the predicted and measured results of surface hardness. This model can be used to predict the surface hardness when surface grinding.
