This paper initially reviews the research on machining of titanium with conventional methods and ultrasonic machining process. Experimental research is subsequently presented on ultrasonic drilling of titanium (ASTM Grade-I) under established experimental conditions using two different tool materials-high carbon steel and titanium alloy; three different abrasive materials-alumina, silicon carbide and boron carbide with three different grit sizes-220, 320 and 500. The results obtained for machining rate and tool wear rate were presented as main effects plots. It was concluded that tool material properties such as hardness, fracture toughness affect the machining performance of USM very significantly. Machining efficiency is also found to improve with increase in the hardness and coarseness of the abrasive media used for preparation of the slurry.

Abstract


This paper initially reviews the research on machining of titanium with conventional methods and ultrasonic machining process. Experimental research is subsequently presented on ultrasonic drilling of titanium (ASTM Grade-I) under established experimental conditions using two different tool materials-high carbon steel and titanium alloy; three different abrasive materials-alumina, silicon carbide and boron carbide with three different grit sizes-220, 320 and 500. The results obtained for machining rate and tool wear rate were presented as main effects plots. It was concluded that tool material properties such as hardness, fracture toughness affect the machining performance of USM very significantly. Machining efficiency is also found to improve with increase in the hardness and coarseness of the abrasive media used for preparation of the slurry.
