Abstract

This paper on the outer-blade slicing analyzes the effects of the side relief angle α 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 Fz. (2) The difference between the maximum values of Fz under the different conditions of (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 α decreases the maximum blade deflection DB largely, while too large a value of a increases DB due to lessening of the flexural rigidity of the blade. (4) The difference between the values of DB under the different conditions of 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 VL largely. (7) VL increases with an increase in the case of α close to zero, while the tendency is reversed in the case of α exceeding a certain value.
