It is important to conduct confirmation tests to verify the
improvement in the machining characteristics of MMCs,
implying that the factors and levels chosen for the experiment
provide the desired result. Table 6 shows that the increase
in S/N ratio from the initial cutting parameters is 3.99 dB for
surface roughness, which implies that the surface roughness
qualities have improved. It was observed that experimental
results were close to the predicted values and they were falling
with in the confidence limits.
