Error Sensitivity Analysis of a Novel A/B Bi-Rotary Head

Abstract:

A novel A/B bi-rotary head is designed which can be used on five-axis machine centers. The motion of pitching and swing can be achieved by controlling the output angle and velocity of motors. Anti-backlash control method can be applied to eliminate the transmission backlash. The error sensitivity model is also established using matrix differential method, and the influence of internal errors on the integrated errors is obtained. The results show that the more sensitive errors can be identified from all errors which need to be controlled rationally.
