Assumptions for development of the new centering – leveling device

Abstract

Precision angle measurements are widely used in manufacturing circular scales which are the main component of angle encoders. Accuracy of such encoders have a great impact on production quality, costs and pace in various fields of activity. Therefore accuracy control leads to improvement of production. To evaluate the accuracy of a scale it has to be test and compared to a standard reference. It is achieved through calibration process, requiring complex methodology and equipment. Therefore design of a new centering – leveling device is presented. Moreover, methods and means for encoder scale calibration are discussed as well as the problem of centering and leveling of the scales is presented in the paper. The preliminary results of tilting and centering of the adjusting plates of the device are analyzed.
