Abstract: Metal machining is one of the common practices in various newlinemanufacturing industries. A large number of process and product variables newlineare involved in metal cutting. Since it is not possible to consider the entire set newlineof variables and operations, an effort is made to investigate only a few aspects newlineand to analyze the trends in the economic way. Since the cutting zone temperature in metal machining influences newlinemore on flank wear of cutting insert and surface roughness of finished newlineproduct, greater attention is focused towards the minimization of cutting zone newlinetemperature. Minimization of cutting zone temperature for minimizing the newlineflank wear and surface roughness, theoretical versus experimental correlation newlineanalysis, Acoustic Emission (AE) signals analysis, external tip cooling newlinethrough metallic cooling fins and Minimum Quantity Lubricant (MQL) and newlinetool geometry analysis are applied and analyzed in this research work. The selection of optimal cutting parameters such as cutting speed, newlinefeed rate and depth of cut for every machining process is a very important newlineissue in order to maintain the quality of machined products, to reduce the newlinemachining costs and to increase the production rate. The cutting conditions set newlineby such practitioners are too far from optimal conditions. Hence, in this newlineresearch work, the theoretical and experimental correlation analysis is carried newlineout as preliminary experiment by selecting cutting speed, feed rate and depth newlineof cut as parameters and the effects of the selected parameters on cutting zone newlinetemperature are analyzed. It is found that, there is a good agreement theoretically and experimentally observed cutting zone temperature values. newlineAlso the tool-chip interface temperature is predicted using DEFORM-2D newlinefinite element solver for all the test conditions. It is found that there is a good newlineagreement between the predicted and experimentally observed cutting zone newlinetemperature values for all the test conditions.
