Machining condition giving high residual compressive stress in carbon steel were examined experimentaly in this study. The relation between dimensions/configuration of cutting edge and resisual stress was analyzed mainly. The influence of coner radius of the sutting edge, muner cutting edge clearance angle and feel per tooth were checked. The residual stress was measurted by using X-ray. The diffrection profiles were appoximated to Gausian curves, and the peek positions were decided by using a method of nonlinear least squares. The followings became obvious as results of analyses. When the per tooth was made smaller with an appropriate corner radius and small cutting edge clearance angle, high compressive residual stress occured in the right angle direction of machining. The penetration depth of residual stress became deep when high compressive residual stress occurred.
