Jul 17, 2022Abrasive jet machining (AJM) is the process of using a high-pressure stream of abrasive particles to remove material from a workpiece. This process can be used to remove material from a wide variety of materials, including metals, glass, ceramics, and plastics. AJM is a versatile process that can be used to create a variety of shapes and textures.

Electrochemical Grinding (ECG) is a combination of electrochemical (Anodic) dissolution of a material, according to Faraday's Law, and light abrasive action. The metal is decomposed to some degree by the DC current flow between the conductive grinding wheel (Cathode) and the work piece (Anode) in the presence of an electrolyte solution.

Abstract. This paper reports the development of the mathematical modeling of an abrasive electrochemical grinding (AECG) process. In AECG a metal-bonded grinding wheel is used instead of a graphite or metal wheel-electrode used in electrochemical grinding (ECG). Therefore, the mechanical abrasion is combined with the electrochemical dissolution.

Electrochemical grinding (ECG) uses electrical current and an abrasive wheel to cut without heat stress, burrs or mechanical distortions. Oxidation stops the cutting. Then an abrasive grinding wheel removes the metal oxide, restarting cutting. Cathode-anode current flow, conductivity and electrochemical reactivity determine the ECG machining rate.
