However, the dressing wheel will show high wear and it is not possible to efficiently condition the grinding wheel with these conventional dressing tools because chattering of the grinding wheel occurs. The novel Electrical Discharge Conditioning (EDC) technology has been developed for conditioning metal bonded, conductive grinding wheels.

The paper presents the mechanism of material removal in electrical discharge diamond grinding, which integrates electrical discharge machining and diamond grinding for machining electrically conducting hard materials. The role of current and wheel speed on the material removal rate, the grinding forces and power is studied to elucidate the issue.

Apr 12, 2017· Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.

Size of the tool electrode used in micro-EDM is of the order of few tens to few hundred micrometers and the energy supplied is also small. This feature of micro-EDM demands in-situ fabrication of tool electrodes. This paper proposes the development of a simple self-adaptive positioning and feeding system for in-situ tool grinding based on block electrical discharge grinding principle.
Electrical discharge grinding (EDG) is a hybrid process involving energy of sparking as well as mechanical grinding. The machining of thin and fragile material is very difficult for manufacturing industries and rapid demand of requirement could not be achieved. Electrical discharge machining is more acceptable machine tool for

A workpiece made of electrically conductive material and a shaped tool are immersed in a dielectric fluid. Rapid pulses of electricity pass through the tool (+ve electrode) and the negatively charged workpiece, leading to a spark discharge. Plasma forms and, along with the sparks, vaporises the workpiece material removing material 'chips', which are then flushed away by dielectric fluid.

A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods. Its use is limited to electrically conductive materials. ECM can cut small or odd-shaped angles, intricate contours or cavities in hard and ...
