Analysis of effect of Minimum Quantity Lubrication on different machining parameters Cutting Force, Surface Roughness and Tool Wear by Hard Turning of AISI-4340 Alloy Steel a Review

This paper deals with the study of various machining process and show the effect of different cutting parameters on the properties of material. There are several important factors in the product quality which are surface finish, cutting temperature, tool life and coolant quality. The use of coolant generally causes life of tools and it also maintains work piece surface properties without damages. There are some negative effects and cutting fluid wastes in industries. In this paper, attention is focused on minimum quantity lubrication and recent work and some outcomes of machining factors from minimum quantity lubrication are presented. The review of the literature suggests that minimal fluid application provides several benefits in machining. It has been found that hardened alloy steel like AISI 4340 is known to be difficult to cut and a little knowledge is available in use of MQL for cooling. The main objective of the study of MQL is to reduce the surface roughness during machining and machining cost of cutting fluid. The minimum quantity lubrication also affects the surface finishing, reduce tool wear and reduce the cutting force. This paper provides a review of present work and some limitations of conventional cutting fluid machining and growing opportunities for development of the next generation MQL in machining operations.
