Title: Methods for Performance Evaluation of Single Axis Positioning Systems: Dynamic Straightness
Published: October 25, 2013
Abstract: Many new ultra-precision linear positioning systems are finding their way into emerging technologies that are requiring exceptional straightness performance during both static/quasi-static and dynamic positioning conditions. However, a standard test method for characterizing and specifying dynamic straightness for single axis linear positioning systems does not currently exist. As a result, many manufacturers and users of linear positioning systems have developed their own internal methods and standards, which have led to customer confusion and ambiguity. To help mitigate confusion, members form industry, academia, and government are working to develop a new positioning performance standard that includes a test method for characterizing straightness of linear positioning systems under dynamic conditions. In this paper, we discuss a test method for characterizing dynamic straightness. Descriptions of measurement setups, measurement and analysis procedures, and suggestions for reporting dynamic straightness results are presented.
