SHAPE MEASURING INSTRUMENT, SHAPE MEASURING INSTRUMENT ADJUSTMENT METHOD AND SHAPE MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a shape measuring instrument, a shape measuring instrument adjustment method and a shape measurement method that can improve operation efficiency by simplifying workpiece position adjustment.SOLUTION: A shape measuring instrument 1 performing a rotation copying measurement to a rotor shape workpiece and a linear copying measurement thereto comprises: a rotary table 10 that has the workpiece loaded and rotates around a prescribed rotary axial line; a rotation copying measurement section 20 that measures a displacement of a surface of the workpiece loaded on the rotary table 10; a linear copying measurement section 30 that measures a contour shape of the surface of the workpiece loaded on the rotary table 10 along a prescribed measurement axial line; and a movement mechanism 40 that causes the linear copying measurement section 30 and the rotary table 10 to be relatively moved in a direction crossing the measurement axial line. The linear copying measurement section 30 and the rotary table 10 are adjusted to a relative position where the measurement axial line passes the rotation axial line.
