Further remarks on the modelling of elastic modulus of grinding wheels

Abstract A modified non-dimensional group for modelling the elastic modulus of grinding wheels is proposed and thoroughly discussed. Specific attention is paid to the temperature effect on the variations of the modulus. A new factor called processing parameter is successfully defined to reflect the behaviour of a wheel influenced by the manufacturing processes. The well constructed 3-D diagram shows that the variation of the non-dimensional elastic modulus is well represented by the present prediction and that the proposed method is convenient for both theoretical and engineering applications. In order to offer guidelines for engineers in drawing simple relations from the presented governing parameters, formulation procedures are clearly detailed through some illustrative examples.
