This paper describes the part which forms exit burr at the end of ground surface. In order to clarify the burr formation process, the deformation of corner shape at the exit end is observed. The effect of plastic flow in the ground layer and the residual stock removal are investigated. The results obtained are as follows : (1) In the vicinity of the workpiece edge, the plastic flow in the ground layer is expanded at an angle of 20-25° with respect to the grinding direction regardless of the edge angle of the workpiece. (2) The burr root is formed by the plastic flow part below the depth of cut. The burr is mainly formed by the residual stock removal at the workpiece edge. (3) In the growing up process of exit burr, the part width of about 30μm at workpiece edge (i.e. residual stock removal) turns to burr.
