The result shows that lowest value of surface Grinding roughness was obtained for NanoMQL of hard steel in comparison with soft steel under grinding Jaya algorithm environments such as wet MQL and NanoMQL. Hence to improve the performance of soft steel Modeling the modeling and optimization of surface roughness were carried out. The significant parameters NanoMQL were considered for model development and validity of model determined through ANOVA Surface roughness Analysis of variance . Lastly the optimal values were determined using Jaya algorithm for min- imum surface roughness and the percentage
