A Study on Machinability of Ti-6Al-4V ELI (Grade 23) Titanium Alloy Using Micro-EDM Process
摘要
Titanium alloys have a broad array of macro and micro applications, from being used as biomaterials to aerospace industries for their superior corrosion resistance, low density, and immense biocompatibility. The machinability of titanium is relatively low owing to its poor thermal conductivity, strong chemical affinity, and low elastic modulus. An experiment is carried out to study the machinability of Ti-6Al-4V ELI with respect to tungsten carbide micro tool. Voltage, tool rotation speed (TRS), and feed rate are taken as input process parameters. The selected input process parameters have been found to have a significant impact on material removal rate (MRR) and tool wear rate (TWR). It is found that voltage and TRS are the most influential input parameters for MRR; for TWR, voltage is the most prominent factor.
