OPTIMIZATION OF PROCESS PARAMETERS IN ELECTROCHEMICAL DEBURRING OF DIE STEEL USING TAGUCHI METHOD

In this paper, an experimental investigation into electrochemical deburring (ECD) of die steel is carried out. The Taguchi method is used to formulate the experimental plan to analyse the effect of each electrochemical deburring process parameters on change in burr height and to predict the optimal setting for each ECD process parameter. Taguchi’s L16 orthogonal array design is chosen for the experiments. Maximization of change in burr height is selected as the required surface quality at lower machining time. The signal-to-noise ratio and the analysis of variance are used to find the optimum levels within the window of parameters selected and to identify the order of importance of the process parameters. Finally, a confirmation test is conducted, which verifies that optimal ECD parameters can be determined effectively so as improve the rate of change in burr height.
