When drilling a titanium alloy, its low heat conductivity causes slow dispersion of heat evolved as a result of friction with a drill. Then a significant build up of heat at the cutting edges occurs, resulting in the increased welding phenomenon of chips at the tool flank as well as increased chipping. Therefore, it becomes difficult to determine a suitable cutting condition and tool material. In this work, intermittently decelerated feed drilling tests with high speed steel drills for a Ti–6%Al–4%V alloy were carried out on a CNC machine tool to improve the rate of chip removal. The results show the formation of easy-to-eliminate chips, reduced chip clogging, increased chip removal. Consequently, heat is readily dispersed to the exterior and the build up of heat at the cutting edges is reduced, resulting in the increased tool life by two times over a conventional drilling. Intermittently decelerated feed drilling is an effective method in drilling titanium alloys.
