This investigation was made in order to find out a distribution of residual stress on the surfaces ground under various grinding conditions obtained by changing an actual depth of cut, number of grinding and a grinding process under a constant state of a chip cross sectional area. The surfaces of the specimens where ground by only up cut, only down cut and both up and down cut, respectively. The experimental data were analyzed by using both the Dolle-Hauk method and the integral method which takes into account of the stress gradient. As a result, the residual stress on the surface of one pass grinding shoed higher tensile stress when a larger actual depth of cut tool place. And the residual stress of down cut grinding was higher than that of up cut. By repeating another re-grinding on the same surface, the residual stress translated into a compressive stress and then converged into a certain level. On the contrary, the stress gradient changed to positive side in such case.
