The quality of a machined surface is becoming more and more important to satisfy the increasing demands of sophisticated component performance, longevity, and reliability. The objective of this paper is to analyze the performance of precision turning using conventional lathe on Ti6Al4V under dry working conditions. Various parameters that affect the machining processes were identified and a consensus was reached regarding its values. The proposed work is to perform machining under the selected levels of conditions and parameters and to estimate the, cutting temperature and surface roughness generated as the result of the machining process. ANOVA is used to find the percentage contribution of each parameter to the surface roughness and cutting temperature.

The objective of the work is to perform precision turning using a conventional lathe on Ti-6Al-4V under dry working conditions. Various parameters that affect the machining process were identified and a consensus was reached regarding its values. Precision turning is a type of machining where, very low feed rate and depth of cut are being used to machine using a cutting insert with a lower nose radius. The cutting parameters considered for the experiments include the cutting speed, feed rate, depth of cut and nose radius. The machinability of Ti-6Al-4V was investigated by some researchers using coated carbide inserts, but its machinability using advanced cutting inserts was not explored adequately. PVD coated carbide cutting inserts with different nose radius and constant rake and clearance angle are being considered for experimentation. The experimentation was designed based on Taguchi's L 27 orthogonal array. Three different levels of cutting parameters were being considered for the experimentation. The turning experiments were carried out on a conventional variable speed motor lathe under dry working conditions. The machinability is evaluated in terms of surface finish achieved on the work piece, tool wear encountered and tool life achieved by the inserts for various precision machining time and the cutting zone temperature generated during the process.
