Optimal Setting of Machining Parameters for Turning Inconel 625 Using Coated Tool

Article Preview

Abstract:

Inconel 625 materials are widely used in the chemical, aircraft and shipbuilding industries due to thermal resistant retaining mechanical properties. These materials are generally hard to machine material due to their high strength and high work hardening tendency. Surface roughness (SR) and material removal rate (MRR) are widely considered as demanding aspect causing poor quality in machining. Optimization of cutting parameter is essential for the achievement of high quality and high rate of production. In this work, TiAlN coated cutting tool was used for CNC turning of Inconel 625 under dry conditions and optimum cutting parameters for each performance measure is obtained by employing Taguchi techniques. Analysis of variance (ANOVA) was employed to study the performance characteristics in turning operation.
