Abstract
Wire EDM is an eco-friendly, non-traditional machining process with no contact between the workpiece and the wire electrode and has a widespread usage in the field of medical industry, automobile industry, etc. The purpose of this present work is to optimize various wire EDM input parameters for machining of INVAR 36. The Taguchi technique was used to carry out the optimization. The control parameters like pulse-on-time (Ton), pulse-off-time (Toff), servo voltage (SV) and wire feed rate (Wf) were chosen to analyse the effect of various parameters on material removal rate (MRR) and surface roughness (SR) of INVAR 36 alloy. To optimize the material removal rate (MRR) and surface roughness (SR), a total of 9 (L9 orthogonal array) experiments were performed. The Taguchi method was applied by using MINITAB 17 software to maximize MRR and minimize SR. The optimum level of process parameters for MRR was found to be 25 µs pulse-on-time, 46 µs pulse-off-time, 5 mm/min wire feed rate, 30 V servo voltage and for surface roughness (SR) 25 µs pulse-on-time, 19 µs pulse-off-time, 3 mm/min wire feed rate, 20 V servo voltage.
