2. Material removal rate
The objective of this study is to find out the optimum levels for the process parameters so that the surface roughness value will be minimum and rate of material removal will be maximum in a vertical machining center and to check the optimality by developing empirical models.

ANOVA result showed that for both condition of tool orientation, feed and depth of cut have significant impact on material removal rate. Interaction of speed and DOC also have significant impact on it. For surface roughness, feed and speed has main effect and interaction of feed and speed also has significant impact for 45 degree tool orientation and for 90 degree orientation along with above factors a combination of speed and DOC is also significant.
