electrical discharge grinding


A study of electrical discharge grinding using a rotary

electrical discharge seems to be unavoidable and is the dominant factor for the flatness of machined surfaces [6]. Electrochemical discharge grinding (ECDG) combines the material removal actions of electrical discharge grinding with electrolytic attack to remove materials from electrical-ly conductive workpieces. There is a possibility that

Wire Electrical Discharge Machining - an overview

The Hybrid-µEDM -DT110 developed in Singapore, as shown in Fig. 8.2 [3], is a three-axis hybrid machining center which combines micromilling, turning, EDM, wire EDM, wire electrical discharge grinding, and grinding processes on single machine bed. The strokes of the X, Y, and Z axes are 200 mm, 100 mm, and 100 mm, respectively.

Electrochemical grinding - Wikipedia

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid.

PPT) ELECTRICAL DISCHARGE MACHINING | anil kumar - Academia.edu

ADVANTAGES AND DISADVANTAGES EDM is a method of machining parts that cannot be done by conventional machines. "Since the tool does not touch the workpiece, there are no cutting forces generated; therefore, very fragile parts can be machined" . The shape and also the hardness of the materials being used make EDM ideal. Impossible to have ...

Shaping Soft Robotic Microactuators by Wire Electrical

Due to fabrication limitations, low complex void geometries are the de facto standard, severely restricting attainable motions. This paper introduces wire electrical discharge grinding (WEDG) for shaping the inflatable void, increasing their complexity. This approach enables the creation of new deformation patterns and functionalities.
