Investigation In Wire Electric Discharge Machining (Wedm) Of Titanium Alloy (Ti6al-4v) For Biomedical Applications - Review

:Ti-6Al-4V (grade 5 titanium alloy) material is commonly used for biomedical applications especially in dental implants. Titanium alloys are some of the recently developed advanced materials having tremendous mechanical properties including high yield strength, high strength to weight ratio and excellent in biocompatibility. Titanium alloys having poor machinability and not able to machine in conventional machining process. These alloys can be machined effectively using some unconventional machining methods. Wire-Electro Discharge Machining (WEDM) is one such advanced machining technique working to machine intricate shapes like hardest metals like titanium. The objective of the study is to investigate and identify the optimal process parameters in electric discharge machining of Ti-6Al-4V. The machining parameters such as voltage, discharge current, pulse on time and pulse off time are considered as input parameters and material removal rate (MRR),tool wear rate (TWR) and surface roughness (Ra) are considered as response parameters. The design of the experiment strategy was followed by selecting the Taguchi optimization technique (L9) to optimize the process parameters. By analysis of variance, the most influential parameters will be found for wire electric discharge machining process.
