328 Assessment of a New Driven Rotary Cutting Tool on High Speed Machining of Ti-6Al-4V

Abstract

This paper presents an assessment of a new driven rotary tool in the turning operation of a titanium alloy at high cutting speeds. Two types of cutting tools were used for comparison : a stationary tool (ST) and a driven rotary tool (DRT). Experiments were conducted at different feeds, depths of cut, cutting speeds, and rotary speeds. Tool wear and cutting forces were recorded and analyzed. Tool life equations were derived for both tools. The results show that a significant advantage of the DRT is its long tool life that eliminates the need for frequent indexing of worn insert during high speed machining of titanium alloys.
