Experimental Investigations on Machining Characteristics of Titanium in Ultrasonic Impact Grinding

In the present study, an effort has been made to experimentally explore the temperature effect in ultrasonic impact grinding of pure titanium, using high-speed steel, tungsten carbide and stainless steel tools. Two output parameters namely material removal rate and tool wear rate (at three different slurry temperatures 10°C, 27°C, and 60°C) were selected to access the capability of ultrasonic impact grinding. The results suggested that the temperature has not significant effect on the material removal rate and tool wear rate in ultrasonic impact grinding of commercially pure titanium. Further more, material removal rate and tool wear rate were greatly influenced by work-tool material relative hardness.
