-Electrical discharge machining (EDM) process, at present is still an experience process, wherein selected parameters are often far from the optimum, and at the same time selecting optimization parameters is costly and time consuming. In this paper cryogenic treatment is used for increasing the material removal rate and lowering the tool wear rate. cryogenic treatment is a process of keeping th...

The effect of deep cryogenic treatment (DCT) on the artificial ageing kinetics a SiC particles reinforced aluminum alloy composite (SiCp-Al) is experimentally studied in this paper. evolutions both macro-properties (i.e., yield strength and ultimate tensile strength) microstructures (precipitates) have been investigated by set hardness tests, microstructural observations (scanning electron micr...

In this research, Böhler K340 cold work tool steel was subjected to three different heat treatment protocols, conventional (CHT), shallow cryogenic (SCT), and deep (DCT). The study compares the effect of SCT DCT on microstructure consequently selected mechanical properties (micro- macroscale hardness impact toughness). shows no significant difference in after treatments. However, microhardness ...

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 repo...
