Review on Research Trends in Electric Discharge Machining for Biomedical Application
EDM is one of the methods of non-conventional machining process. It works on the principle of thermal electric energy between tool and workpiece. Various advancement has been made on EDM process like use of ultrasonic assisted tools, rotatory tools, using water as dielectric fluid and powder mixed dielectric fluid. From last few years EDM has been used for surface modification of biomaterials as machining by EDM has many benefits over other methods used for machining of biomaterials. This paper reviews recent advancement of EDM in biomedical field.
