The applications of electrochemical machining are increasing because of increasing requests of industries for materials with high strengh and high hardness. Regular ECM uses a tool with spicified profile shape that is similar to final shape of workpiece. In this reasearch a nozzle that delivers electrolyte to the machining gap is used for machining cylinderical workpieces. By moving the electrochemical jet on the rotating workpiece the desired profile will be shaped on it. Using high voltage and big machining gap is the most important difference between this methode and other conventional ECM mehods. پرونده مقاله
