The blade being quite free from deflection is in an unstable state in the outer-blade slicing process and easily deflected by a slight lateral force. The deflection causes a participation of the side face of the blade in grinding, followed by an increase of the lateral grinding force. It makes further deflection of the blade itself. The object of this paper is to clear how both sides of the groove are generated by the blade deflected because of a lateral grinding force. For the purpose, the state of a blade in slicing was estimated from the geometry of the groove obtained by interrupting grinding in the middle of a pass. That is discussed in relation to three components of the grinding force measured at the same time. Furthermore, the effect of the grinding conditions is studied experimentally on the geometry of the groove and the cut-off accuracy. The cut-off surface on the convex side of the blade showed a higher flatness. On the contrary, that on the other side showed a concave shape to the vertical direction. The kerf-loss was mainly generated on the concave side of the blade, and became larger with an increase of the asymmetry of the blade section and the projection of the blade from the flange.
