This paper investigates the technological capabilities of a micro machining process for performing Wire Electro Discharge Grinding (WEDG). In particular, micro Wire Electrical Discharge Machining (μWEDM) is employed in combination with a rotating submergible spindle to perform WEDG.
Electrodischarge diamond face grinding (EDDFG), a hybrid machining process comprising diamond face grinding (DFG) and electrodischarge machining (EDM), has been developed for machining of electrically conductive difficulttomachine very hard materials. The process employs simultaneous synergetic interactive effect of abrasion action and electrodischarge action.
Electrical Discharge Surface Grinding (EDSG) is much like electrical discharge machining except that the electrode is a rotating metal matrix composite (MMC) tool, processed by reinforcing abrasive particles in a conducting metal matrix by powder metallurgy route.
PDF Abstract. The objective of this work is to develop a finite element method (FEM) based mathematical model to simulate the hybrid machining process of grinding and electric discharge machining (EDM), named as Electrodischarge abrasive grinding (EDAG), for temperature distribution in the workpiece. ...

2. The Principle of InProcess ElectroDischarge Dressing Electrodischarge machining for inprocess dressing [12] generates electrical energy between an electrode and the metal bond of a grinding wheel by spark electrodischarge and initiating arc electrodischarge. This electrodischarge energy erodes the workpiece and the electrode.
The goal of this research was to use the wire Electrical Discharge Machining (EDM) to profile a metal bond diamond grinding wheel, and then study the wear and grinding performance of the EDM trued wheel. Diamond wheels are known to exhibit low wheel wear for precision grinding of ceramics but create difficulty in creating precision trued forms.
This type of machining process, sometimes referred to as spark machining, die sinking or burning, is when an electrical discharge is used to shape materials. In some ways it can be a very versatile and accurate way to prototype and produce parts with hard metals .
