This paper deals with a burr-formation mechanism on a Work end by using a finite element method. In the calculation, grinding temperature and cutting force for a cutting point are considered. Therefore, the thermal and mechanical stress distribution and plastic deformation of the workpiece end are derived. The main results obtained are as follows : (1) The grinding temperature causes a plastic deformation on a workpiece-surface layer, while it is not enough to produce a macroscopic plastic flow. (2) The plastic flow is produced mainly by the grinding force. (3) In the vicinity of the workpiece end, the plastic-flow layer is expanded at an angle of 21-27° with respect to the grinding direction. The results shows a similar tendency of experimental ones.
