Abstract

This paper details an in-depth assessment of the effect of processing conditions on the performance of grinding process. The experimental data was collected based on the design of Taguchi L18 fractional factorial mixed level scheme. In addition to the standard processing conditions in grinding, viz. number of passes, depth of cut and work speed; duty ratio and voltage were introduced in this comprehensive analysis. Five process outputs chosen: material removal rate (MRR), surface roughness, surface hardness, normal grinding force and tangential grinding force. The results of the investigation showed that MRR is significantly controlled by work speed, duty ratio and depth of cut. The MRR increases linearly with work speed, and the resulting improvement was observed to be 26%. The surface roughness decreases with an increase in number of passes as well as the voltage. The hardness increases linearly with the depth of cut. A decrease in normal force (Fn) with voltage is observed. All the normal probability plots for the five process output indicate linear relationship between probability and residuals.
