| Abstract |
It is necessary to drill micro holes in some hard brittle materials. Comparing with electro
discharge machining, electrochemical machining and laser machining, the ultrasonic machining
(USM) has unique advantages in hard brittle materials machining. The aim of this paper is to
present experimental work that has been done in micro holes machining by micro USM. The main
machining mechanisms of USM are discussed. It is pointed out that the contributions of each
mechanism to material removal rate are different in different cases. By using micro USM with
workpiece vibration and tool feeding in constant rate, the experiments of micro holes machining are
carried out and the process laws of tool wear are studied. Some phenomena are found and the
causation of causing these phenomena is analyzed. A Ø13μm micro hole is obtained. |
