Geometric inspections of large-scale parts, at affordable costs and within reasonable measuring time, are necessary in manufacturing industries. For example, to improve the reliability and safety of wind energy system (WES) over the lifetime of 20 years, WES manufacturers need to inspect a variety of components such as main bearings, gears and pitch bearings [1]. Multi-axis measuring devices including coordinate measuring machines (CMMs), gear measuring instruments (GMI), form testers, etc. are versatile instruments for these applications. As key components of multi-axis measuring devices, rotary tables provide a quick rotary positioning of components to assess measurands.
