<P>PROBLEM TO BE SOLVED: To provide an apparatus and method for measuring a circular mechanical component in which measurement precision is prevented from being reduced, a measurement target can be easily measured without being accurately restricted and fixed, and a man-hour or the like required for component exchange can be reduced. <P>SOLUTION: A laser displacement gauge 2 is used which is capable of measuring a width dimension of a part, in a circular mechanical component W, that becomes a chord of a circle forming a circular portion therein. The laser displacement gauge 2 is confronted to a shape measurement target of the supported circular mechanical component W, and the laser displacement gauge 2 is caused to measure the width dimension of arbitrary two or more parts each of which becomes the chord. Arithmetic means 4 transforms the width dimension of each of the arbitrary two or more parts measured by the laser displacement gauge 2 into coordinate points of both two end points in an orthogonal coordinate system and calculates a diameter and a central position of the circular portion that becomes the shape measurement target, from an approximate circle which is calculated from the coordinate points. <P>COPYRIGHT: (C)2012,JPO&INPIT |
