The Effects of Cryogenic Treatment on Cutting Tools

IOP Conference Series: Materials Science and Engineering, 2017
Enhancing the cutting tool life is important and economic factor to reduce the tooling as well as manufacturing cost. The tool life is improved considerably by 92 % after cryogenic treatment. The cryogenic treatment is a one-time permanent, sub-zero heat treatment that entirely changes cross-section of cutting tool.
