The Use of the Size Effect in Grinding for Work

1/1/2007The grinding strategy was successfully tested with an industrial process which demonstrated the potential of using the size effect of specific energy for an in-process work-hardening by grinding. Low cutting speeds in combi- nation with low depths of cut resulted in negligible thermal effects and compressive workpiece residual stresses.
