Abstract

In the first part of this paper, the differences between metrology for serial lunematic machine tools (SKM) and parallel kinematic machine tools (PKM) are described, especially for the measurement of geometric deviations. These differences lead to special problems for the calibration of parallel lunematic machine tools, partly comparable to the problems for the calibration of five and multi-axis serial lunematic machme tools. In an initiative of the German NC Gesellschaft, the German association for NC technology, rules for testing PKM were established. A comparison of available test equipment for PKM, organised also by the NC Gesellschaft, resulted in a specification for future test equipment for PKM. The rules and specifications are discussed, also with respect to the applicability to multi-axis serial kine
