Electro Chemical Grinding (ECG) Electrochemical grinding combines both electrolytic action (90%) and physical grinding (10%) to provide precision, burr-free and stress-free results. Owing to the electrolytic reaction, ECG eliminates the need for a separate deburring operation. It is also a low stress machining operation that avoids potential ...

Electrical Discharge Machining (EDM) is one of the earliest and most widely used non-conventional machining processes. In recent years, the use of EDM has increased significantly in industries, mainly due to the extensive use of hard and difficult-to-cut materials, i.e. hardened steels, carbides, titanium alloys, nickel super alloys and so on.

Figure 2 shows the idea of the present method which was proposed in the previous paper [] and originally named as wire electrochemical grinding (WECG) after the well-established wire electro-discharge grinding (WEDG) method [].However, the naming is changed to wire electrochemical turning (WECT) in this paper because turning is more appropriate to …
Electrical discharge grinding (EDG) is becoming more prevalent in the manufacturing of polycrystalline diamond (PCD) tools. This paper concerns investigation of the effects of machining parameters, as well as finishing in-feed, to the surface quality obtained when using EDG to erode PCD. With the aid of the morphological findings, different PCD erosion …

So, a new hybrid machining process (HMP) has been discovered, namely electrical discharge diamond grinding (EDDG). This EDDG is the combination of electric discharge machining (EDM) and grinding wheel with metal-bonded diamond grit. EDDG gives better performance than EDM due to the spark generation the rotating diamond wheel.
