The author has devised a test for evaluating the accuracy of calculation algorithms and used it to establish the accuracy of the software of fourteen CMMs offered by world top manufacturers. Using a minimum number of measuring points, the author calculated various geometrical elements with arbitrary shape deviations and the relationships between them, and compared the obtained results with the reference results. The input data were entered from the keyboard to the computer working with a CMM. Therefore the error of the final calculation result was introduced only by the software and the computer, and did not include the errors of the CMM. The computer and the software were treated as a "black box". The same test set was used for all software.
