Abstract

A synchronous control system model is proposed to study the reasons and mechanism that cause the non-synchronous errors in dual-driving systems on gantry-type tools with traveling bridge. The proposed dual-driving model is based on dynamics theory analysis

from which the effects of mechanical cross coupling and different frictional characteristics on non-synchronous errors can be described. Experiments are carried out on the DK-1200 machine tools to verify the proposed model. Non-synchronous errors are measured and compared with Matlab/Simulink simulation results when machine tool moves at a uniform velocity and S accelerate/decelerate curve. The results show that the coefficient of correlation between simulated and practical experimental results for the model with mechanical coupling and friction reaches up to 0.861 8. The model can reflect the state of motion of the machine tools well

and the friction difference and mechanical coupling are un-ignorable factors in solving the problem of non-synchronous errors.
