Abstract

An experimental investigation was conducted to determine the effect of drill point geometry and drilling methods on tool life and tool wear in drilling titanium alloy, Ti-6Al-4V. Uncoated carbide drills with different type of geometry under various cutting speeds and drilling methods were used in the investigation. Experimental results revealed that both the drill geometry and drilling techniques affect the tool wear and tool life performance when drilling Ti-6Al-4V. It was also found that peck drilling outperformed direct drilling in terms of tool life all cutting speeds investigated. Non uniform wear and chipping were the dominant failure mode of the tools tested under most conditions.
