This paper deals with a formation mechanism of the chipping on the workpiecd end by using a finite element method and an experimental method. In the calculation, cutting force in the contact zone is considered. Therefore, the mechanical stress distribution near the workpiece end are derived. The grinding is carried out to clarify the effect of work speeds and depths of cut on the chipping size. The main results obtained are as follows : (1) The Compressive stress region in front of the cutting point acts an important role to remove the material when wheel is located sufficient distance from the workpiece end. (2) The chipping of the workpiece end is mainly caused by the tensile stress behind the engaging cutting edge. (3) The chipping size is closely related to the grinding forces.
