PURPOSE:To make it possible to positively measure the accuracy of the dimension of a reproduced product without changing a measuring instrument even if the product's curved surface varies by measuring it based on the data on the procedures for measurement and the reference values of a master model from which the product to be measured was reproduced, memorized in advance. CONSTITUTION:A product 22 to be measured is arranged on a table 24, and by the operation of a keyboard 40, data memorized in an RAM of an arm mechanism controller 32 are selected based on positional information memorized in a disk 42, and an xy table 10 and an arm mechanism 16 move. Next, arms 17, 18, 19 are operated based on the positional information memorized in the disk 42 and a probe 20 moves over the item to be measured 22. At this time, the amount of displacement between the curved shape of a master model measured in advance and that of the item to be measured 22 is detected by the probe and by this accuracy of dimension of each curved surface to be measured is obtained. |
