On the basis of second order surface roughness model the predicted results according to the optimized input process parameters are given in the Table 7. Confirmation test is done to check the acceptability of the developed second order model and the experimental results thus found on the basis of optimized input parameters are given in Table 8. It could be observed that the predicted results are in acceptable zone with respect to the experimental results and thus it is concluded that the developed model seems to be acceptable.
Discrimination on the basis of the developed second model the predicted results according to the optimized values input process parameters are given in the Table 9 and Table 10.
Confirmation test is done to investigate the acceptability of the developed second order model and the experimental results thus found on the basis of optimized values input parameters are given in Table 11.
