This approach enables the creation of new deformation patterns and functionalities. termed electrical discharge diamond grinding (EDDG) utilizes a metal bonded diamond-grinding wheel and subjects the work to the simultaneous influence of dia-mond grains and electrical sparks which cause abrasion and surface melting, respectively. Wire Electric Discharge machining WEDM INTRODUCTION Wire EDM Machining (also known as Spark EDM) is a unique adoption of EDM; it is an electro thermal production process similar in configuration to band sawing, in which a thin metal wire acts as a saw in conjunction with deionized fluid, used to conduct electricity, is used to cut through metal by means of heat from electrical sparks. Between both electrodes—here the tool and the work piece—a difference in potential with a frequency larger than 100 kHz is applied, which results in sparks. Abrasive machining method where controlled spark discharges from an electrically charged, rotating wheel grinds the workpiece surface. fO�[�"���Y�H2�� ��Z���� L@[�D�f�I�g`�� � �i- The WEDG process is used to create various moulds to cast rubber microactuators.

Known by many other names, including spark machining, arc machining and (inaccurately) burning, the EDM process is conceptually very simple: an electrical current passes between an electrode and a … US3122628A US255412A US25541263A US3122628A US 3122628 A US3122628 A US 3122628A US 255412 A US255412 A US 255412A US 25541263 A US25541263 A US 25541263A US 3122628 A US3122628 A US 3122628A Authority US United States Prior art keywords … Electrical Discharge Grinding (EDG) and conventional grinding are two different processes with different removal mechanisms and are typically used to machine Polycrystalline Diamond (PCD). Of Mech. In this paper, a new EDD (Electrical discharge dressing) device was developed for the dressing of metal bonded diamond arc grinding wheels.
