ACO for Improving Surface Finish in the Turning Operation Using Nano-Coated Tool

S. Prabu, S.K. Rajesh Kanna

In general, tool life and surface finish are the important aspects considered in evaluating the performance of a machining process. In this research, increased tool life with better surface finish has been obtained by using TiAlCn nano-coated cutting tool for turning operations. TiAlCn nano-coating has made on the turning tool by the process of chemical vapor deposition (CVD) and have been used to machine the mild-steel work-piece by varying cutting parameters namely spindle speed, feed rate and depth of cut to identify the machining characteristics namely tool wear rate and surface finish. The obtained results have been compared with the carbide tool and found that the nano-coated tool produced smoother surfaces than the carbide tool. Also the obtained result have been given as input to Ant Colony Algorithm (ACO) for identifying the optimized cutting parameters which yields better surface finish and improved tool life. The ACO will identify the best spindle speed, feed rate and depth of cut to yield better surface finish with lesser wear rate to increase the tool life.
