Abstract

The high speed steel is used as a cutting tool, since it has good quality and reliability at cheaper rate when compared to other cutting tools. So it is very important to increase the ability of the tool further for its reliability. So the best way is to increase the hardness. We have brainstormed to find out alternate tool materials. One novel method namely dipping the ordinary tool bit in a cryogenic solution, which improves the wear properties of the cutting tool consequently machining time is also reduced. Cryogenic treatment of high speed steel is one of the developments in manufacturing field. It offers much better wear resistance and hardness for the high speed steel. The conventional cryogenic treatment process involves cooling down the samples to 93k (-180°c) soaking for 12 seconds and then slowly heating back to room temperature. In this experimental investigation a sequence of methodology is adopted to arrive at an optimum solution having two sample pieces of round of EN8 & EN19. A method called deep cryogenic process, subjects steel components placed in a specially constructed tank to temperature around 77k (196°c) for half an hour using liquid nitrogen as the refrigerant.
