Abstract
A cutting edge adjustment device for a cutting tool for adjusting the position of a cutting edge of a cutting insert by causing movement of the cutting insert includes a rotary member for producing the movement. The rotary member is formed into a shape in which a substantially cylindrical portion having a constant radius and a cam portion having a cam face whose radius is gradually increased in a manner corresponding to the amount of the movement are arranged in a direction of a rotational center axis. The cam face is formed in such a manner as to have a section in which a radius is linearly increased, and consequently, the unit rotational angle of the rotary member on the rotational center axis is proportional to the unit movement amount of the cutting insert.
