Optimization of cryogenic treatment parameters to maximise the tool wear of HSS tools by Taguchi method

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used to arrive at the optimum CT parameters. The various levels of cryogenic treatement parameters have their own influence upon the flank wear resistance of the HSS tools. In this study, teh Taguchi method has been used to optimize teh process parameters for cryogenic treatment of commercial HSS tools. For optimization, four iterations of Taguchi design have been used to arrive at the optimum CT parmeters. The experimental results demonstrate that the soaking temperature was the major parameter influencing the flank wear rate for all samples, but, other parameters were found to have negligible effect on the flank wear rate.
