INVESTIGATION OF TEMPERATURES AND RESIDUAL STRESSES IN SPEED STROKE GRINDING VIA FEA SIMULATION AND PRACTICAL TESTS

The new technology of speed stroke grinding promises to meet the industrial demand for a high-efficiency, high-quality finishing process. The surface layer properties of the workpiece, such as residual stresses, are a vital factor in the quality of the workpiece and must be considered when choosing process parameters. This paper discusses the residual stresses resulting from practical speed stroke grinding tests of hardened steels using CBN grinding wheels, as well as an in-development FEA model for the thermal aspects of speed stroke grinding.
