AbstractThe research reported in this paper aims at improving the dynamic performance of motion systems by analysing and mapping the non-uniformity of feed motion within the travel area. This paper (a) develops the real-time measuring of the feed motions through built-in position encoders, (b) considers the feed motion as a space-time random process, and (c) applies analysis in order to evaluate and map the dynamic performance. The dynamic performance as a “dynamic imprint” of the entire motion system is represented by the dynamic/statistic characteristics of feed motion. The transfer function of the motion system as a dynamic operator, which transforms prescribed motion into actual motion, is applied to model the dynamic performance. The results of the experimental investigations, analysis, and mapping of the dynamic performance indicate a wide range of industrial uses of the developed approach for certification, diagnostics, and tool path optimisation purposes to achieve highest accuracy for a particular motion system.
