Abstract
In this paper propose is a model with which grinding results can quantitatively be given from the viewpoint of cooling and lubricant actions of water soluble type grinding fluids. Experimental results are compared with calculated results by using this model. Main conclusions are as follows: (1) Cooling action is measured as heat transfer rate of grinding fluids and lubricant action is measured as coefficient of lubricant on the grinding wheel surface. (2) Dimensionless grinding results Gr* are given by: Gr*=μ*α·h*-β, where h* and μ* are dimensionless cooling and lubricant moduli defined from heat transfer rate and coefficient of lubricant. (3) Close agreements are obtained between experimental and calculated values of workpiece surface temperature and grinding forces.
