With its high grit retention and easiness to true and dress, the vitrified bond is widely used as a bond material for cBN and diamond grinding wheels. By giving electrical conductivity to the vitrified bond, application of electrical discharge trueing/dressing and detection of a workpiece position by electrical contact sensing will become possible.

the discharge area is very small like a single point [5]. In order to overcome the shortcoming of mechani-cal grinding, as well as enlarging the discharge area of WEDG, a WEDG process with line-segment wire discharge (called line-segment WEDG in this paper) was explored for machining the conical surfaces of needle valve seats. In the

Abrasive Electrical Discharge Grinding (AEDG) . Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of Al-SiC composite, removal rate of the AEDG process (t e = 10 m s, and n = 500 rpm) is about 5 times greater than that of EDM process, and about twice of EDG process.
