A study on surface roughness of workpiece when grinding SKD11 and SUJ2 steels using Al2O3 and CBN wheels

Abstract

This paper presents a study on surface roughness of workpiece when grinding SKD11, SUJ2 steels using Al2O3 and CBN grinding wheels. The method on modeling and predicting of surface roughness of workpiece in the grinding theoretical research was applied. However, when applying this method, it is necessary to identify the value of the roughness adjust factor in practical case. In this paper, this factor was found by experimental process when surface grinding SKD11 and SUJ2 steels by Al2O3 and CBN wheels. It helps values of calculating surface roughness to be similar to experimental datas.
