Powder-mixed electro-discharge diamond surface grinding (PMEDDSG) is an efficient process for shaping hard materials, such as Ti-6Al-4V. It is widely used in many applications, including aerospace industries and medical implants. This process is a combination of conventional surface grinding with electrical spark machining with the presence of
using wire electro discharge grinding (WEDG) process, a variation of electro discharge machining process, is considered. The advantage of this process is that very small micro tools (less than 0.1 mm diameter) can be produced by eroding the tool material through electrical discharges.

Electrical Discharge Conditioning for Indexable Insert Grinding, grinding wheels using Electrical Discharge, Electrical discharge conditioning for indexable Electro Discharge Machining - NPTEL Electro Discharge Machining (EDM) is an electro-thermal non-traditional machining, The electrical resistance of such plasma channel.
Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject ...

Understanding Electrical Discharge Machining Electrical Discharge Machining EDM, once considered a "non-conventional" machining method, is now the fourth most popular machining method. The first three are milling, turning, and grinding. One of the major reasons for the turnaround is today's EDM machines have dramatically increased their cutting ...
2. INTRODUCTION Electro Discharge Machining (EDM) is an electro-thermal non- traditional machining process, where electrical energy is used to generate electrical spark and material removal mainly occurs due to thermal energy of the spark. EDM is mainly used to machine difficult-to-machine materials and high strength temperature resistant ...
Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. Fundamentally, the electric erosion effect is understood by the breakdown of electrode material accompanying any form …
