THE EFFECT OF CRYOGENIC COOLING ON GRINDING FORCES

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