Application of the Taguchi Technique for WEDM Parameters for Tungsten Carbide

In this paper the parametric response for wire electrical discharge machine (WEDM) for pure tungsten were processed to investigate. The relationships between material removal rate (MRR), a surface roughness (SR) and density of surface crack density (SCD), based on the process response were explore with the significance of machine variables parameters such as voltage (Vo), peak current (Ip) and wire speed (Ws). The experiment has been used L9 Taguchi array's design of experiment (DOE) to determining the effect of machine condition each of experiment were ensured successfully under statistic evaluated as the data result were investigated by analysis of variance (ANOVA). The result seems that an increase in discharge current and voltage could cause an increase in MRR, surface roughness and density of crack. The specimen was observed by scanning electron microscope using for investigating the surface response at separate conditions the characteristic of distribution crack length per area it was an optimized condition for the surface crack density. The methodology of Signal to noise ratio and ANOVA was used to analyze the main effect to processes response the result of research also identification parameters for cutting tungsten utility approach in the manufacturing process.
