Abstract

In modern manufacturing technology, a lot of extensive research work has been carried out in drilling operations for achieving better hole quality. Drilling is one such machining process which is widely used in aeronautical and automotive industries for structural assembly. Titanium alloy (Ti-6Al-4V) is attractive for many applications due to their superior properties. However, they are regarded as hard-to-machine materials. Drilling is an important machining process since it is involved in nearly all Titanium alloy applications. It is desirable to develop cost- effective drilling processes for Titanium alloy and improve the cost-effectiveness of currently-available processes. In the view of above facts, an attempt has been made to study the machinability during dry drilling of Ti-6Al-4V. The main objective of the study is to determine the favourable drilling conditions for Ti-6Al-4V hole quality (surface roughness, and Burr) and chip type based on design of experiments.
