MULTI OBJECTIVE OPTIMIZATION DURING ABRASIVE WATER JET MACHINING OF MONEL– 400 METAL USING GREY RELATIONAL ANALYSIS

This paper investigates the optimal setting of process parameters such as traverse speed, abrasive flow rate and standoff distance which influences the surface roughness and material removal rate during Abrasive water Jet machining of Monel-400 work-material and Garnet-80 mesh as abrasive particles. Experiments are carried-out based on Taguchi and Grey relational analysis is used to analyze the data. For the purpose of experimentation L9 orthogonal array is used as per Taguchi design of experiments. Grey relational analysis is used to find the optimal conditions of each process parameters on response variables such as surface roughness and MRR. Finally confirmatory test is carried-out and checked the adequacy of the process.
