Abstract: The big challenge of the mass production firms is concentrated for achieving high quality products with good dimensionability with high productivity, less wear on the cutting insert, less use of cutting fluid, within less time. This paper present review of an dissertation work of an investigation of turning process parameters on hard EN 31 material, for optimization of surface roughness, material removal rate, machining time in wet and minimum quantity lubrication system. The experiment will carry out by considering four controllable input variables namely cutting speed, feed rate, depth of cut and insert nose radius. This experiment will also present the relation between chip formations and controllable variables along with chip thickness and chip colors from which its effect on insert wear, quality of product can be easily found out, because of chip morphology gives indirectly the effect of it on the insert wear. In this dissertation work minimum quantity lubrication system will use for reducing the cutting zone temperature properly and very fastly. Finally comparison will carry out between wet and minimum quantity lubrication system from which one can easily indentify which system is better for higher productivity along with high surface finish . This work will also present the inventory concept in production. The design of experiment and optimization of surface roughness, material removal rate, machining time will carry out by using response surface methodology (RSM). Central composite design method will use (CCD) for the total experimental design work and its analysis and also for optimization of turning process parameter by which wastage of the machining time, power can be avoided.

Keywords: mass production, minimum quantity lubrication, inventory concept, RSM, CCD.
