Electrochemical machining (ECM) is a non-traditional process used mainly to machine hard or difficult to cut metals such as Ni-base super alloys, composites, stainless steels etc.
Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. Optimization of electrochemical machining process parameters: Combining response surface methodology and differential evolution algorithm Ali Mehrvar, Ali Basti, and Ali Jamali Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering 2016 231 : 6 , … There are many multi objective optimization (MoGA) techniques involved in machining process parameters optimization including multi-objective genetic algorithm (MOGA), strength Pareto evolutionary algorithm (SPEA), micro genetic algorithm (Micro-GA), Pareto-archived evolution strategy … The electrolyte flow is very important to ensure the complete removal of heat and gases produced by the reactions at either electrode and to let current flow to enable charge transport [ 15 ]. Precise Electrochemical machining (ECM, PECM) is based on the ability of a metal to dissolve as a result of oxidic reactions occurring in the medium of the electrically conducting solution (electrolyte) under electric current influence. Electrochemical machining (ECM) is a non-traditional machining process uses the principle of Faraday to remove metal from the workpiece. Reactions occurred during electrochemical machining process for machining of iron (Fe) workpiece with NaNO3 as electrolyte : *It has been established that metal dissolution reaction is the main or the only reaction that occurs at the anode. Developments on electrochemical discharge machining: A review of experimental investigations on tool electrode process parameters Pankaj Kumar Gupta, Akshay Dvivedi, and Pradeep Kumar Proceedings of the Institution of Mechanical Engineers, Part B: Journal … A new hybrid fuzzy-Artificial Bee Colony algorithm (Fuzzy-ABC) for the optimization of electrochemical machining (ECM) process parameters is presented in this paper. ECM has been identified as a potential process energy which has the capability to undergo hybridization with other process energies.
Electrochemical Machining of SG Iron: Effect of Process Variables on Surface Roughness Parameters - written by Bishnu. Those difficult to cut metals demand high energy to form chips, which can result in thermal effects due to the high temperatures inherent to the process in the chip–tool interface. weight of substance produced during electrolysis is proportional to current passing, length of time the process used and the equivalent weight of material which is … Specialized processes under ECM. Several other process parameters, such as nozzle motion speed, nozzle diameter, electrolyte flow velocity, and electrolyte concentration, have significant influences on the machining result.
