Optimization of process parameters for Surface Roughness and Material Removal Rate of H13 die tool steel for wire EDM using Taguchi Technique

Abstract

In this paper, Study on Material expulsion rate and Surface Roughness of H13 die tool using Wire cut EDM process is focused. H 13 chromium hot work steel is far and wide used in hot and freezing work tooling purpose. Due to its excellent amalgamation of high robustness and fatigue resistance H13 is used more than any supplementary tool steel in tooling applications. The H-13 hot die-hard substance dimension 103.70 mm x 13.95 mm has been utilized as a work section substance in favor of the current research, wire electrode of brass having standard diameter 0.25 mm is used as electrode. Four Parameters (TON, TOFF, WF and voltage) are chose to consider its impact on cutting rate and surface harshness. Taguchi Plan of technique is used in the experimentation & analyze by Minitab 15 programming. Observations brings voltage is the most noteworthy boundaries on SR where Ton and Toff are less critical and also observed that MRR amplify with enhance in Ton and WF and diminish on escalating of Vg and Toff.
