This paper presents the optimization and mathematical modelling of machining parameters in Photochemical Machining (PCM) of SS316L. Twenty-seven experimental runs base on full factorial (33) Design of Experiments (DoE) technique were performed. The control parameters considered were the etchant concentration, etching temperature and etching time. The response parameter was Undercut (Uc). The effect of control parameters on undercut was analysed using Analysis of Variance (ANOVA) technique and their optimal conditions were evaluated. It was found that etchant temperature and etching time are the most significant factors for undercut.Keywords

The present work is an attempt to determine optimum machining parameters for turning of Inconel 718 in dry conditions with multiplayer CVD coated carbide tool (TiN/Al2O3/TiCN). The turning of Inconel 718 is performed on precision, heavy duty, and robust NH-22 Lathe. Investigation of machining parameters involved experimenting with different feed rates (0.04-1.04 mm/rev), different depth of cuts (0.2-1.15 mm), and different cutting speeds (1.91-93.73 m/min) while turning.
From the experimentations, it can be stated that the optimum machining parameters; Cutting speed=40.17 m/min, feed=0.1 mm/rev, and depth of cut=0.5 mm are best suited for semi-finish turning of Inconel 718 with CVD coated multi layer carbide tool based upon tool life.

The Aerospace industry's advancements have resulted in an increase in demand and production optimization of super alloys. These superalloys, such as Inconel 718, are generally characterized by very high strain hardening coefficients and as a result they are extremely difficult to machine. Inconel 718, a heat resistant super alloy (HRSA), is utilized in the hottest parts of a gas turbine able to withstand high operating temperatures typically between 540°C and 1000°C. CVD coated carbide tools with high hardness, wear resistance, and chemical stability offer proven benefits in terms of machining performance when machining Inconel 718.The present work is an attempt to determine optimum machining parameters for turning of Inconel 718 in dry conditions with multiplayer CVD coated carbide tool (TiN/Al2O3/TiCN).
