摘要
In order to evaluate the accuracy of a serial-parallel type machine tool, an error analysis is presented. Two different methods are adopted to derive the error model, namely the linkage kinematic analysis and the differential vector method, by which the effects of strut manufacturing tolerance and actuating error on the tool position and pose are investigated. The computational results show the influences of the actuating error and the strut length error on the machine tool inaccuracies.
