Abstract

Unique features of micro electro discharge machining (micro EDM) include its ability to machine hard and brittle materials and absence of mechanical contact force for the machining of fragile components. Therefore, micro EDM has emerged as one of the predominant complementary micro machining technology with applications in diverse industries such as biotechnology, aeronautical, automotive. However, to achieve high aspect ratio (>10) micro hole drilling, micro EDM needs to overcome inherent problems associated with debris removal as accumulated debris causes arcing and hence hinders the machining process. This paper presents the experimental results of ultrasonic vibration assisted micro EDM. Using this method, drilling of high aspect ratio (micro holes in austenitic stainless steel with an aspect ratio of 20) has been achieved in this study. Another benefit of ultrasonic vibration is that the savings in machining time. It is also noticed that the ultrasonic vibration causes some shape distortion and produces rougher machined surface.
