Optimization Of Cylindrical Grinding Process Parameters On Material Removal Rate Of En21am Steel

Abstract

Grinding is the machining processes, which improve surface quality and dimensional accuracy of the work piece. Various process parameters, which affect the cylindrical grinding operation, are depth of cut, material hardness, and work piece speed, grinding wheel grain size, number of passes, material removal rate and grinding wheel speed. Speed and feed are critical factors because increasing the both speed, and feed has an adverse impact on surface roughness but high material removal cause reduction in surface roughness. Cylindrical grinding is one of the important metal cutting processes used extensively in the finishing operations. Metal removal rate and surface finish are the important output responses in the production with respect to quantity and quality. In this thesis, is to arrive at the optimal grinding conditions that will minimize surface roughness and maximize metal removal rate when cylindrical grinding of EN21AMsteel is done for the optimization of grinding process parameters. During an experimental work input process parameters i.e. speed, feed, depth of cut is optimized using Taguchi method. 3D modeling done by CREO parametric software.
