Abstract: A circular shape characteristic measuring device includes a shape measuring device that obtains measured data by measuring a profile shape of a circular cross-section of an object to be measured having the circular cross-section, and a computation device that calculates a circular shape characteristic of the circular cross-section. The computation device includes: an input device configured to input one of three parameters including a cutoff value of the filtering process, a minimum number of samples, and a ratio of a radius of the circular cross-section to a radius of a gauge head; a parameter table that stores a relationship between the three parameters, and based on the input parameter, determines the other two parameters; and a sampler configured to perform sampling of the measured data based on the minimum number of samples.

Abstract: When detecting a tolerance of a shape of a measured object having a complicated shape that makes it difficult to perform a continued measurement, a plurality of partial measurement data that are set are retrieved. Next, a reference position is set from first partial measurement data. Then, each of the partial measurement data is combined into one data using the reference position. Further, the tolerance is calculated using the combined data.
