Abstract:

This paper presents the effect of grinding parameters on surface roughness when external cylindrical grinding SKD11 steel using Hai Duong grinding wheel. Three grinding parameters mentioned in this study include workpiece velocity, depth of cut, and longitudinal feed rate. The factor selected as the criterion for evaluating the grinding process is the surface roughness of the workpiece. The Hai Duong grinding wheel, Cn80.G.V1,400x50x207x35m/s, was used in this study. The experiment was conducted with 15 experiments according to the Box-Behken matrix. After analyzing experimental results, the three grinding parameters significantly affected surface roughness. The influence of the interaction between the grinding parameters on surface roughness was also analyzed in this study. This study has also built a regression model on the relationship between surface roughness and the grinding parameters with the correlation coefficient 96.69%. This is the basis for selecting and controlling the value of the grinding parameters in order to obtain the surface roughness according to specific requirements. Finally, the further research is also mentioned in this paper.
