The effect of cryogenic cooling on grinding forces

Abstract

Grinding forces are important parameters to judge the performance of any grinding process. Cryogenic cooling in grinding is a new concept to control the high grinding zone temperature without polluting the environment. The paper presents a hypothesis on the mechanics of grinding under cryogenic cooling. Experiments have been carried out to study the effect of cryogenic cooling on grinding forces and to check the validity of the hypothesis. The results indicate substantial reduction in the grinding forces under cryogenic cooling over range of infeed and dressing procedure for different commonly used steels.
