This paper discusses the ideal solution for minimizing surface roughness in grinding operation on EN9 steel by using pressurized steam jet as a coolant and analyse it using Grey Relational Analysis methodology. The collective analysis of the measured results were performed with the help of commercial software package Minitab 17 and the experiments were conducted using L18 orthogonal array experimental design technique. The test conditions matrix included three different values of steam pressures, two different values of feed rates, three different values of depth of cut and three surface treatment conditions which were used as parameters during grinding operation, while cutting speed was kept constant at 2840 rev/min. The determination of optimum cutting conditions for minimizing the surface roughness was observed analytically under the effect of different cutting parameters on surface roughness. The experimental results revealed that the optimal combination of machining parameters for obtaining minimum surface roughness was in the sequence of depth of cut followed by pressurized steam jet, feed rate and annealing surface treatment. The predicted values and measured values were found to be fairly close, which indicates that the developed model can be effectively used.
