Experimental study on geometric and elastostatic calibration of industrial robot for milling application

摘要

The paper is devoted to geometric and elastostatic calibration of industrial robot for milling application. Particular attention is paid to the analysis of the experimental results and enhancement identification routines. In contrast to other works, the identification results have been validated using separate set of measurements that were not used in calibration. The obtained geometric and elastostatic models essentially improve robot positioning accuracy in milling applications.
