【 摘 要 】

In order to improve the machining precision of multi axis CNC machine tool, contour error reduced by mechanical transmission and electric control factors, servo multi axis CNC machine adopteds cross coupling parameter selection problem, stability is not strongm and so on, this paper proposed a control method of cross coupled contour error compensation, control method of cross coupled contour error compensation based on a cross coupled contour error compensation the model, X axis, Y axis and Z axis of the simulation platform, Simulation results show that the simulation and experimental results show that control contour error compensation algorithm based on ross coupling error compensation method calculation process is simple, the contour error, the accuracy of interpolation control improved, meet the real-time, high-speed, efficient CNC system interpolation requirements, as well as NC interpolation in high reference significance.
