  • According to the feed system of a CNC machine center, based on the analysis of mechanical properties of a double-drive ball screw feed system, with the friction of its worktable considered, the theoretical model of synchronization error is developed and solved by MATLAB/Simulink. The impact of structural parameters and other factors on the synchronization error is analyzed. The synchronization error of the worktable under uniform motion and S-shaped curve motion is measured with experiments and compared with the results of the theoretical model. The results show that the synchronization error of the feed system is caused by the twist angle due to the geometric error and different structural parameters of the two sides of the worktable during movement. The model can predict well the synchronization error.
