Influence of dressing parameters on surface roughness of workpiece for grinding hardened 9XC tool steel

Abstract

Abstract The quality of final machining surfaces in a grinding process, such as the surface roughness and the accuracy depends on the grinding and dressing parameters. In order to improve the surface smoothness and precise tolerances, many grinding and dressing parameters need to be optimized. However, several dressing parameters, i.e., the rough dressing, the final dressing, and the dressing without depth of cut affected on the surface roughness have not yet been mentioned in the grinding process. This paper presents an optimization of these parameters on the surface roughness for grinding the hardened 9XC steel using grinding wheel Cn80MV1 400x40x203. An experimental system was set up to evaluate those parameters. The optimal values of these parameters were determined by using Minitab ® 16 for analyzing data from the experiment.
