Abstract

Parallel kinematics machines (PKM) present a promising new formation of machine kinematics. But, their application is limited due to insufficient positioning accuracy, caused by errors of the transformation model and indirect position measurements. The theoretically attainable machining accuracy of machine tools is further decreased by unsolved calibration problems, which are the most important obstacles concerning the introduction of new machine tools with parallel or hybrid kinematics. This paper presents a conceptual improvement based on a direct position measurement in Cartesian coordinates, which overcomes these problems.
