Parameter optimization of a cylindrical grinding operation for the quality of surface finish

摘要

The most important parameter describing surface integrity is surface roughness. In the manufacturing industry, surface must be within certain limits of roughness. Therefore, measuring surface roughness is vital to quality control of machining workpiece. This thesis presents Parameter Optimization of a Cylindrical Grinding Operation for The high Quality of Surface Finish. The objective of this study is to perform experiment using Cylindrical Grinding Machine. The other purpose is to investigate the effect of parameters parameter which are work speed, diameter of workpiece and depth of cut that influences the surface roughness on carbon steel (AISI 1042). Besides that, the aim of this study is to determine optimum cylindrical grinding process parameters using the Full Factorial method. The surface roughness were measured using Perthometer S2 and evaluated according to the change of the grinding conditions. Mathematical model was developed to predict the surface roughness using the experimental results. With the help by STATISTICA software, ANOVA have been used for this purpose and an optimal condition has been found out. As a result, the diameter of workpiece , gave more significant effect to the surface roughness compare to the other two parameters which are the work speed, and depth of cut.
