Abstract

This paper focuses on investigating the optimization of process parameters using Taguchi L9 Orthogonal array method for machining operations in turning of Inconel 781 with the aid of special tungsten carbide inserts. The optimization of speed(s), feed(f), Material Removal Rate (MRR) and Temperature(T) considered with relation to the tolerances achieved and accuracy of the machining is investigated. Tests are carried out with absolute accuracy in response to the optimization performance. The factors considered for testing the machining operations tends the surface quality of work material relative to the MRR are analysed. Experimental results show that the turning operation through optimized parametric approach results in developed surface machining quality, performance and less materials consumption induced.
