Abstract

A new 6-D measuring device for rotary table calibration calibration W. Schroder, J. Braasch & T. Schlicksbier Dr. Johannes Heidenhain GmbH, Germany Abstract Like linear feed axes, rotary tables have six types of systematic error. These errors are mainly caused by the inaccuracy of the manufacturing and assembly process of the rotary table, which results in a disturbing movement superposed on the theoretical rotation. The six systematic errors of rotary tables can be di- vided into two groups, the first being the translational error, i.e. two eccentricity errors along the local x- and y-axis, and the axial runout along the local z-axis (rotating axis), and the second being three angular errors, i.e. two wobble errors about the local x- and y-axis, and the angular error about the local z-axis. This paper presents a calibration device capable of measuring all six system- atic errors of rotary tables simultaneously in a single continuous measurement according to ISO 230 [1, 2]. The
