Abstract:

In this research paper, the different process parameters of wire cut electrical discharge machining process are studied. And work piece material for which parameters are to be optimized is H 13 Hot die tool steel material with a 0.25 mm coated wire by using Taguchi methodology. The selection of machining parameters in any machining process significantly affects surface finish, production rate and production cost of a finished one component. The experiment has been formulated with the help of Design of experiment and grey relational analysis. The Taguchi method is used to formulate the experimental layout, to analyse the effect of each parameter on the machining characteristics, and to predict the optimal choice for each WEDM parameter. Experimentation is planned as per Taguchi’s L8 Orthogonal Array (OR).In this experiment optimize the input process parameters Pulse on time (T ON), Pulse off time (T OFF), peak current (IP), Wire feed rate (WF), Wire tension (WT), Servo voltage (SV) of a WEDM process for a response parameters Surface Roughness (SR), Material Removal Rate (MRR) and Kerf Width (KW) for a H 13 HOT DIE TOOL STEEL. the experimental results are to be analysed using analysis of variance (ANOVA) to find out significant contribution of machining parameters over response parameters and the optimal combinations of the parameters are to be determined.
