Residual stress in grinding

Results of investigations on residual stress in surface grinding are presented in the paper. A coefficient “B” combining power density and wheel/workpiece contact time was developed. Experimental set-up and software to estimate the coefficient during grinding are described in the paper. Experiments were carried out for surface plunge grinding for several workmaterials in a wide range of grinding conditions. The influence of process parameters on the coefficient B as well as the relation between B and maximum residual stress were experimentally evaluated. The usefulness of the coefficient to predict residual stress in surface grinding was proved.
