Surface Roughness Prediction in Grinding Process of the SKD11 Steel by using Response Surface Method

Abstract

This study was performed to to develop a surface roughness model in the grinded process by using the response surface method (RSM). The experimental research was performed in the grinding the SKD11 steel by using CBN grinding wheel (symbol of HY-180x13x31.75-100#). The experimental matrix was developed basing on the Box - Behnken plan with 15 experiments. Experimental results were analyzed by Minitab 16 statistical software to develop a surface roughness model. The proposed model is a quadratic function of the grinding parameters such as workpiece velocity, feed rate, and depth of cut. The model of surface roughness was verified by experimental with very consistent results. The proposed model can be used to calculate the surface roughness values of the machined part in machining process the SKD11 steel by using CBN grinding wheel.
