This paper on the outer-blade slicing analyzes the effects of the side relief angle a of the blade on the slicing mechanism theoretically. The main results obtained are as follows. (1) The larger α, the smaller the maximum value of the lateral grinding force component F_z. (2) The difference between the maximum values of F_z under the different conditions of γ_s (γ_s denotes the average half-tip angle of the abrasive grains on the blade side face) decreases with an increase in α. (3) A moderate value of a decreases the maximum blade deflection D_B largely, while too large a value of a increases D_B due to lessening of the flexural rigidity of the blade. (4) The difference between the values of D_B under the different conditions of γ_s decreases with an increase in α. (5) The flatness of the cutoff surface generated on the blade deflection side is improved largely with a moderate value of α, while that on the opposite side is deteriorated. (6) A moderate value of α decreases the kerfloss V_L largely. (7) V_L increases with an increase in γ_s in the case of α close to zero, while the tendency is reversed in the case of a exceeding a certain value.
