Abstract :
In modern contribution the tool cost play a vital role in the total manufacturing cost is approximately 50%. In EDM, tool wear is a major problem, because of it the geometrical accuracy and form of the tool are not reproduced on the workpiece exactly while machining. Due to these reasons the tool wear has to be carefully handled while planning electrical discharge machining operations of micro holes. This paper studies the influence of various factors contributing micro hole machining by die sinker EDM with micro electrodes rod of diameters 300µm, 500µm, 900µm with process parameters current, time-on, time-off. The objective of the research is to investigate the wear behaviour of electrodes with Taguchi’s L9 Orthogonal array method to optimize the electrical discharge machining process variables for achieving minimum tool wear rate.
