High-throughput dry drilling of titanium aluminide

Abstract

There is always an increasing interest and demand for the materials with superior properties particularly in aerospace and automobile industries. Intermetallic titanium aluminides have been recognized as the possible material which could be used in high performance applications. The understanding of the machinability during various machining processes is very much essential in order to widen the usage of these materials over various fields of application. Drilling, particularly with high aspect ratio is a complex machining process which has to be explored. In the present work, machinability of titanium aluminide has been evaluated during high through-put dry drilling, based on thrust, torque, surface integrity and chip morphology.

“…Higher feed rates, on the other hand, are responsible for higher tool wear, which results in higher surface roughness (arithmetic average roughness (Ra)). The process parameters also affect the hole diameter, which increases with increasing feed rate [8][9][10]. When, however, there is an increase in the cutting speed, the mean diameter error is smaller [11].…”
