Abstract

The most-used tool material in the manufacturing industries is High Speed Steel (HSS). Many researchers have already proved that the cryogenic treatment of tool and die steels is the most effective technology to increase wear resistance and improve surface quality of the machined parts. In this study, we have conducted cryogenic treatment on tool material with three specimen groups of AISIM2 tool steel. The first group was Conventionally Heat Treated (CHT), the second was Shallow Cryogenically Treated (SCT), and the third group was Deep Cryogenically Treated (DCT). Turning operation was performed on the entire AISIM2 tool steel samples. A stop watch was used to note down the time at the starting and end of each run of turning operation, and tool maker's microscope was used to measure the flank wear at the end of each run. It has been noticed that there is improvement in tool life in terms of flank wear of DCT and SCT as compared with CHT tools. Also, DCT tools reported significant enhancement in cutting life of the tool as compared with SCT.

Introduction

The use of liquid nitrogen and cryogenics in the manufacturing sector clearly has a place in the global emissions reduction battle. With adequate investment, infrastructure and innovation, we can continue to see the benefits of these advanced globally developed technologies. This technology, used for the enhancement of component/tool life is ecofriendly, nontoxic and nonexplosive. It can be clearly said that the component life may be considerably enhanced by such advanced techniques. Because of this, the production requirement of spare parts will be considerably reduced due to long life of machines and vehicles; leading to the reduction in environmental pollution. Many researchers have already proved that the cryogenic treatment of tool and die steels is the most effective technology to increase wear resistance and improve surface quality of the machined parts. The mostused tool material in the manufacturing industries is High Speed Steel (HSS).

During the metal cutting operation, rubbing of the tool along the workpiece surface takes place, causing abrasive, diffusive and adhesive wear, which is called flank wear. Due to this phenomenon, the temperature increases on the work tool interface,
