ICAAMM-2016 Experimental Investigation and Optimization of Machining Parameters of Aerospace Material Using Taguchi’s DOE Approach Anand Pandey a ; Ashish Goyal b ; Rakesh Meghvanshi a Associate Professor, Department of Mechanical Engineering, Manipal University Jaipur, India b PhD Reserarch Scholar, Department of Mechanical Engineering, Manipal University Jaipur, India c Department of Mechanical Engineering, Manipal University Jaipur, India Abstract Precision manufacturing of complicated geometries viz. micro-holes and micro-slits is a challenging task in the metal cutting industries, especially on difficult-to-machine materials viz. metal matrix composites and aerospace materials. WEDM is one of the most demanding machining technologies used currently for such productions using thin electrically conductive wires. In the present investigation, an efforts have been made to produce micro-slits finding applications in micro-diffraction gratings, micro electro mechanical system (MEMS) devices and defence components. An experimentallayout has been conducted using Taguchi’s L-9 Orthogonal array, experimental runs were conducted to predict the response viz. Overcut ona Ni-based super alloy (Inconel-600). In the present research article results have been discussed using Taguchi’s Methodology and micro-structural studies (SEM). An experimental result reveals that overcut increases with peak current and pulse ON –time and decreased with increase of pulse OFF time (75-100µs).
