This paper proposes a fuzzy logic approach for the prediction of residual stresses induced by surface grinding. The surface residual stress of a ground component is considered as a function of ten variables including properties of the workpiece material, grinding wheel and the variation of operation parameters. The system extracts, from experimental results, experience and knowledge about the grinding processes and makes better prediction of residual stresses for a given grinding situation. It is shown that the fuzzy logic method provides a flexible framework for modeling the residual stresses induced by the grinding processes, in spite of the existence of experimental errors.
