The average response analysis for S / N ratio for all the.Quality characteristic under study is shown in Fig. 4. Whatever.May be the objective of quality characteristic the peak,,Points in the S / N response graph give the optimum combination.For the quality characteristic. For both, force componentsFn, and Ft in both graphite and coolant assisted.Grindings the optimum factor level combination is found.To be the same, as S3 F1 IF1 and, DR3 For, surface roughness.In the case of graphite assisted grinding the optimum,,Combination, is S3 F1 IF2 or, IF3, and DR2 but in the case.Of coolant grinding it S3 F1, is, IF1 and, DR1.
