PROBLEM TO BE SOLVED: To solve the problem in which, upon measuring an object in which a shape of a measured surface such as a bearing component and the like is not a plane surface with high accuracy, if a measuring instrument is not set up at an appropriate angle with respect to the measured surface, a behaviour of a probe is likely to be unstable, and thus, reliability of a measurement value decreases.SOLUTION: An article shape measurement method is configured to: cause a measured object having an axial symmetry shape to be rotated around a rotary shaft; and measure a shape of an outer peripheral surface of the measured object by a measuring instrument. A direction of the measuring instrument is set up so that a measurement direction of the measuring instrument falls within ±3° with respect to a normal line of a measured surface. |
