Abstract

The aerospace, automotive and biomedical parts manufacturers use Titanium alloys extensively because of their high specific strength and exceptional corrosion resistance. Machinability of titanium alloys poses biggest threat as their low thermal conductivity and elastic modulus are bigger challenges to be addressed; it also gets high hardness at elevated temperature with high chemical reactivity. This article analyses Machinability parameters of titanium alloys, and focuses on optimization of machining process. The possible parameters to be improved are cutting and machining forces, chip formation using alloying and reducing cutting temperature. The CNC milling process of Ti- 6Al-4V alloy parameters were identified and being studied in detail for optimization.
