Optimization of process parameters in turning of AISI 1045 steel using deep cryogenic treated tools through grey relational analysis

Abstract

Machining was considered as one of the most primary and essential processes in manufacturing. Presently, manufacturing industries need to meet the demands of society through a substantial increase in productivity. Processes involved in manufacturing include turning, drilling, milling, shaping, grinding, broaching, threading, hobbing, super finishing, etc. Turning was considered as the fundamental machining process for the removal of the metal from the outer surface of the rotating workpiece with the help of a cutting tool. The cutting process to produce the desired output performance characteristics was based on the two variables independent and dependent. The independent variables are the tool material and cutting parameters, workpiece material and geometry and types of processes. The dependent variables are the cutting force, cutting temperature, tool wear, surface finish, etc. The tool played a vital role in any machining process and was selected for its quality and cost of processing. Therefore, the process was longer the time of the cutting edge tool in other words was better. Hence, the cutting tool edge gradually increased the machining and the performance decreased. The performance of the cutting tools was improved by improving their material properties. The literature review acknowledges the cryogenic treatment used for tools for extending the tool life in machining. Several experimental works have been carried out with cryogenically treated tools on AISI 1045. Only limited work has been carried out to study the effect of cryogenic treatment on AISI HSS M2, tungsten carbide (TiCN + Al203 + TiN+ZrCN) coating and uncoated tools newline
