State-of-the-art cryogenic machining and processing

Abstract

This paper is a state-of-the-art review of the use of cryogenic cooling using liquefied gases in machining. The review is classified into two major categories namely, cryogenic processing and cryogenic machining. In cryogenic processing also known as cryo-processing the cutting tool material is subjected to cryogenic temperatures as a part of its heat treatment process. The majority of the reported studies identify that cryo-processing can considerably increase cutting tool life especially for high speed steel tools. It also identified that in cryogenic machining a cryogen is used as a cooling substance during cutting operations. The cryogen can be used to freeze the workpiece material and/or cutting tool. The paper concludes that cryogenic cooling has demonstrated significant improvements in machinability by changing the material properties of the cutting tool and/or workpiece material at the cutting zone, altering the coefficient of friction and reducing the cutting temperature.

High performance cutting of advanced aerospace alloys and composite materials

“…smoother surface topography, increasing hardness on the surface and generated compressive residual stress. Besides, the state of the art on cryogenic processing and machining was recently summarized by Shokrani et al [203].…”

Experimental Investigations on Cryogenic Cooling in the Drilling of Titanium Alloy

“…Shokrani et al [2] have studied the effect of cryogenic cooling in machining operations and concluded that milling and drilling operations with different work tool combinations could be attempted. The difficulty lies in machine materials like titanium having low thermal conductivity and has high localized temperatures present at the cutting zone.…”

Environment Friendly Machining of Ni–Cr–Co Based Super Alloy using Different Sustainable Techniques

“…Direct application of cryogen in the cutting zone can reduce the coefficient of friction between sliding surfaces, reduces the cutting forces, increase the hardness of work piece and cutting tool, and lower down the welding tendency of tool and work piece material [24]. In this respect, Dhananchezian et al [25]performed the cryogenic machining of a ferrous alloy using WC inserts.…”
