the new guideline vdi 2634 proposes procedures for the acceptance of point- wise photogrammetric systems ( part 1), and area- based surface measurement systems ( part 2). the standard states that the working accuracy of the machine is evaluated based on making and measuring the diameter of the cylinder on the 25 samples [ 3]. a more current edition is available. while positioning accuracy is determined by direct measurement, test workpieces are produced to determine operational accuracy as this is also influenced by random factors. in may, miles evans and hazel burgess assumed leadership, committed to expanding the company' s offerings and services while building on its solid foundation. it is of direct application to the test- ing of machines which are tied to a particular component, that is for all. the experiment results illustrate the positioning accuracy has been. consequently, manufacturing processes have to satisfy strict criteria concerning the permissible deviation of real geometry from the nominal ( ideal) geometry. ø vdi/ dgq 3441 ø vdi/ dgq 3442 ø ansi/ asme b5. but before getting into a comparison of these standards, it' s necessary to define some critical terminology. publication date. the positioning errors detection and compensation of translational axes for five- axis measuring system based on vdi- 3441 criterion. statistical testing of the operational and positional accuracy of machine tools;
