Abstract

This paper reports on the development of predicted mathematical models for surface roughness when end milling titanium alloy (Ti-6Al-4V) using uncoated solid carbide under flood conditions. Factorial design of experiment coupled with response surface methodology (RSM) were used in developing the surface roughness models in relation to the primary machining variables such as cutting speed, feed and radial rake angle. 3 D response surface contours were also onstructed and used in determining the optimum cutting conditions for a particular range of surface roughness values. The adequacy of the predictive models was verified by ANOVA. Experimental results showed that lower surface roughness can be obtained by employing higher cutting speed, low feed rate and high radial rake angle value when end milling Ti-6Al4V.
