May 15, 2017· Electrochemical action accomplishes most of the machining, the grinding wheel in Electrochemical Grinding have much longer life than a wheel in conventional grinding. The result is a much higher grinding ratio. The dressing of the grinding wheel is required much less frequently. These are the significant advantages of the ECG process.
ELECTROCHEMICAL MACHINING. Introduction . Electrochemical machining (ECM) is a metal-removal process based on the principle of reverse electroplating. In this process, particles travel from the anodic material (workpiece) toward the cathodic material (machining tool). .
Because the tool electrode used in the process does not wear, soft metals can be used as tools to form shapes on harder workpieces. Other applications include deburring, hole drilling, electrochemical grinding, and removal of fatigue cracks in steel structures. The working principles of ECM are described along with the types of electrolytes used.
2.Electrochemical Grinding (ECG) 1.In ECG, the material removal is achieved by combined action of abrasive and electrochemical process energy. The resulting surface has high surface integrity, is burr free, and has negligible distortion. 2.The abrasive particles of the grinding wheel make a contact with the workpiece and the gap between the
for determining the relationship various between process parameters with the various machining criteria and ex- ploring the effect of these process parameters on the coupled responses [5], i.e. the material removal rate and surface roughness phenomena. In order to study the ef- fects of the ECM parameters on the above-mentioned

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. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...
Sep 24, 2018· What is Electrochemical Grinding? It is a process that is quite similar to the electrochemical machining. As per the name, it is the metal removal process which is nothing but the combination of the grinding process and electrochemical process. It is also termed as the "electrolytic grinding" and "anodic machining".

The Burr Free Electrochemical Grinding process is a hybrid method of metal removal combining Abrasive Grinding and Electrochemical Machining (or ECM). ECM is a non-traditional metal removal method developed many years ago based on Michael Faraday's laws of electrolysis.
3. Classification of ECM Process 3.1. Electrochemical Grinding Process In the electrochemical grinding process metal is removed by electrochemical decomposition and abrasion of the metal. In this process electrode wheel revolved in the close proximity to the workpiece. Wheel is made of fine diamond particles in metal matrix.

This paper investigates the effect and parametric optimization of process parameters for Electrochemical micromachining (EMM) of 304 stainless steel using grey relation analysis.
The objective of this experiment was to inspect the runoff of an electrochemical grinding process and to examine the results at a constant voltage and a constant feed rate. Utilising the experiment data, it is expected that relevant information concerning the relationship between process parameters, such as feed rate, voltage,
basis for electrochemical machining of metals. A schematic of the conventional ECM process is presented in Fig. 1. ECM process uses an electrolyte that completes the electric circuitry between anodic workpiece and cathodic tool and prevents the anodic material from being deposited on cathode. Thus, it is reverse process of electro-plating.
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.
