| Abstract | One of the most important kind of material used in engineering field is Titanium. Ti-6Al-4V alloy accounts for approximately 50% of the total world production of titanium alloys. This is due to their different properties like high strength to weight ratio, superior corrosion resistance and ability to withstand high temperature.They are known as “difficult to machine” materials because of their poor thermal property and poor machinability. The cryogenic-treatment is a method to change material properties. It can improve the plasticity of Ti-6Al-4V alloy but along with it reduces the strength to small extent.High-speed machining of the cryo-treated titanium and its alloys which is a highly reactive material is still far away uncertain. So, it is important to study the machining characteristics and optimization of the cutting parameters. In this paper Titanium alloy (Ti-6Al-4V) is cryo-treated and the dry turning experiment is performed in CNC lathe machine by using Coated Carbide cutting tool inserts.The Taguchi Technique is used for designing L9 orthogonal array for three factors namely cutting speed, feed and depth of cut at three levels. The optimal machining conditions are acquired by Signal-Noise-ratio method with respect to surfaceroughness (Ra) and Cutting Force (F). The analysis of variance(ANOVA) and the percentage of contribution of feed,cutting speed and depth of cut for better surface roughness and minimum cutting force is validated using S/N-ratio.According to experimental results, for minimum roughness the depth of cut is a vital parameter followed by feed and then by cutting speed. Similarly, for minimum cutting force the feed is a vital parameter followed by cutting speed and then by the depth of cut. Optimum machining conditions for both resultant cutting forces and surface roughness were obtained. The worn-out surface ofinsert is examined by using the SEM and EDX. |
