DETERMINATION AND OPTIMIZATION OF CYLINDRICAL GRINDING PROCESS PARAMETERS USING TAGUCHI METHOD AND REGRESSION ANALYSIS

By M.Janardhan and Dr.A.Gopala Krishna

Abstract

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 out put responses in the production with respect to quantity and quality respectively. The Experiments are conducted on CNC cylindrical grinding machine with L9 Orthogonal array with input machining variables as work speed, feed rate and depth of cut. Empirical models are developed using design of experiments and response surface methodology. The adequacy of thedeveloped model is tested with ANNOVA. The developed model can be used by the different manufacturing firms to select right combination of machining parameters to achieve an optimal metal removal rate (MRR) and surface roughness (Ra).The results reveals that feed rate, depth of cut are influences predominantly on the output responses metal removal rate (MRR) and surface roughness (Ra).The predicted optimal values for MRR, Ra for Cylindrical grinding process are 62.05 gm/min and 0.816 μm respectively. The results are further confirmed by conducting confirmation experiments
