Investigate the effect of cutting parameter pn Ti6Al4V surface in EDM wire-cut

Abstract

Titanium aloy is aprovide exellent corrosion resistance, a high strength-to-weight-ratio and good high temperature. It’s also have very high affinity to oxygen. A natural oxide layer is always present on the surface. A thicker oxide layer will be formed due to thermal oxidation during machining. So,in this projct will be identify the effct of cutting parameter on Ti6Al4V surface by using EDM Wire-cut. To fine Eight cutting of parameter shoud be understand before running the EDM-wire-cut. The parameter was implicated are electrolisis free, peak current, pulse-ON time,pulse OFF time, voltage flushing rate, wire speed and wire pressure. The parameter will be choose after analysis the result by Design of experiment, (DOE). DOE will be used to get the best combination of parameter to optimize the minimum of Titanium and Aluminum Oxide, and surface roughness and maximum material removal rate. To identify the formation oxide on surface, the Energy-dispensive X-ray (EDX) has been used and Ambios XProfile will be used to know their surface roughness. After get the all result, the confirmation test should be run to know the percentage error after compare with the actual result. The result and discussion will be discuss in this report.
