This paper elucidates the effect of rotational frequency ω of OD-blade on the compliance of its outer edge (hereafter, it is referred to as "edge compliance"), taking up two types of blades welI used for the high-precision slicing of AI_2O_3・TiC. One of those is the sintered metal-bonded diamond blade(Type A) and another is the electroformed diamond blade(Type B). The obtained results are summarized as follows. (1) Young's modulus of Type B is about 3 times larger than that of Type A. (2) The blade deflection around the load point decreases with the increase of ω, but the deflection at the circumferential distant point from the load point increases slightly. (3) In case of the blade of type B, the effect of co on the edge compliance is very small. (4) In the range of ω≦50000 rpm, the decrease ratio of the edge compliance becomes large with the increase of ω. (5) Under the slicing conditions generally used for high-precision slicing, the effect of ω on the edge compliance is very small. (6) The larger the blade protrusion φ from flange, the greater the effect of ω on the reduction of the edge compliance. (7) The edge compliance varies inversely with the decrease of the blade thickness t= under the condition of φ=20t, almost irrespective of ω. (8) With the decrease of the blade diameter, the edge compliance reduces a little under a high constant peripheral speed.
