The elastic deflection of blade is the capital subject of the insufficient cutting accuracy in outer-blade slicing. The blade deflection, caused by the asymmetric wear(observed on the blade cross-section), reaches a steady state in the one-pass cutting process. The authors numerically analyzed the deflection shape in such a steady state, and calculated the cut-off surface geometry. The cut-off surface facing with the inside of a curved blade was concave in a vertical direction. On the contrary, the opposite side surface had good flatness. Using this analysis, we can predict the grinding conditions to keep the cutting accuracy within allowable tolerance.
