Tool wear studies in ultrasonic drilling

Ultrasonic drilling is used to machine brittle and hard materials such as carbides, ceramics and glass which are difficult to machine by many other conventional methods. Tool wear in ultrasonic drilling is affected by a number of factors such as work material, tool material, work material thickness, tool size and cross sectional area, heat treatment of the tool, static load, cutting time and type of abrasives used. Different aspects of tool wear are presented.
