ABSTRACT:
A measuring system includes a coordinate measuring machine for driving a scanning probe and a host computer. The host computer includes a compensation table (53) and a profile analysis unit (54). The compensation table stores, as compensation data, compensation coefficients to correct counter values of a probe counter (415), and compensation radiuses “r” to the workpiece surface concerning central coordinate values of a contact portion, for respective contact directions. The profile analysis unit has a contact direction calculation unit (542), a compensation data selection unit (543), a compensation calculation unit (544). The contact direction calculation unit calculates the contact direction along which the scanning probe comes into contact with a workpiece W, and the compensation data selection unit selects compensation data set up in the compensation table based on thus calculated contact direction.
