METHOD FOR THE DETERMINATION OF SYSTEMATIC GEOMETRIC DEVIATIONS IN TECHNICAL MULTI-BODY SYSTEMS

摘要

The invention relates to a method for the determination of systematic geometric deviations in technical multi-body systems, with a terminal effector and a base, in particular, coordinate measuring devices, machine tools and robots, using one or more pivoting distance measuring systems, whereby the end effector approaches measuring points and, at each measuring point, the distance between base reference points, fixed relative to the base and end effector reference points, fixed relative to the end effector, is measured by at least one distance measuring system. The aim of the invention is to provide a method for determination of geometrical deviations in technical multi-body systems which is more rapid and simpler to carry out and provides reliable results. Said aim is achieved, whereby the end effector is displaced in a raster, aligned with the movement axes of the technical multi-body system and approaches measuring points one after the other, not all of which lie on a plane, the difference between the measured separation and the set position for the end effector reference point is measured at each measuring point and using a kinematic model for the technical multi-body system and the recorded differences, error parameters for each movement axis are determined at the measuring points thereof.
