This paper presents the optimized method of machining process for improved surface finish of AISI 1080 steel which was turned under dry, wet and mist condition.In machining operation large amount of cutting fluids are used for cooling & lubrication purpose. There is necessity to use minimum amount of cutting fluid for machining operations. In this work, to achieve that aim, Minimum quantity lubrication (MQL) method was used to reduce the cutting fluid while machining. A mathematical model will also developed to determine the surface roughness in terms of machining time and cutting tool wear function in terms of the four independent variables: the cutting depth (d), the cutting feed (f), the cutting speed (Vc) and the cutting duration (t). The results application of MQL technique will significantly helps to obtain better performance in compare to dry condition. The purpose of cutting fluid in a machining operation is to cool the work piece, reduce friction, and wash away the chips. The cutting fluid contributes significantly toward machining cost and also possesses environmental threats.
