Effect of cutting parameters on surface roughness in turning of CPM 10V steel

The objective of this paper is to investigate the effect of cutting parameters on surface roughness during turning of CPM 10V steel with a coated cutting tool. Machining of CPM 10V steel and finding a suitable tool is very challenging due to its physical and mechanical properties, especially since the machining of this material has not been extensively researched. The experiments were carried out using an Index GU-600 CNC lathe and the surface roughness R a was measured in process. A three-factorial three-level experimental design was used for the experiments. Statistical method analysis of variance (ANOVA) is applied to study the effects of cutting speed, feed rate, and depth of cut on surface roughness. The results of this study show that feed rate and the depth of cut have the most significant effect on surface roughness. The developed model can be used in the machining industry to predict and analyze cutting parameters for optimal surface roughness.
