Evaluation of Surface Grinding Response Parameters of EN31 Alloy Steel

Abstract

The purpose of this study is to understand the influence of processing parameters on surface roughness and material removal rate of EN31 Alloy Steel. Three input parameters are considered in this study, namely, the speed of the grinding wheel, number of passes and the depth of cut. The L16 orthogonal array design is used to analyse these process parameters. The results show that cutting depth and grinding wheel speed are the most effective parameters affecting material removal rate and cutting depth, and the number of passes is the most effective parameter affecting surface roughness. In addition, result showed that, the maximum MRR is 0.79051 g/sec and the surface roughness is 0.14000 µm. Therefore, it can be concluded that compared with other materials, cutting depth and wheel speed are less effective parameters, but compared with EN31 alloy steel, cutting depth and grinding wheel speed are the most effective parameters.
