It can be used for slotting very thin walled collets. Electrochemical machining (ECM) is an unconventional machining process where material removal is accomplished through controlled anodic dissolution of workpiece. No direct contact between tool and work material so there are no forces and residual stresses. A large number of interacting processes were carefully analyzed: the combined presence of electrolyte flow, electrical conduction, species convection and diffusion, ion migration under an electric field, electrochemical reactions, heat generation and heat transfer. Lazarenko are also credited with proposing the use of electrolysis for metal removal.[2]. (ix) Identify different modules of ECM equipment (x) List four application of ECM (xi) Draw schematics of four such ECM applications 1. However, for a higher feed rate over a larger area, more current would be used, just like any machining process—removing more material faster takes more power. ECM is often characterized as "reverse electroplating", in that it removes material instead of adding it. Valenti, Michael, "Making the Cut." High metal removal rates are possible with ECM, with no thermal or mechanical stresses being transferred to the part, and mirror surface finishes can be achieved. When the potential difference applied between the work piece and tool, positive ions move towards the tool and negative ions towards the work piece. Only electric conductive material can be machined by this method. PEMTec is engaged around the world as an engineering company that specializes in precise electrochemical metalworking.
