Arc Interpolation Control of Numerical Control Machine Tools and Its Realization Based on Multi-axis Motion Control Card

摘要

In order to deduce the algorithm of arc interpolation control of numerical control machine tools and realize its visualization control, the paper studied the interpolation principle and edited the procedure of arc interpolation for two axis servo motors. Then the paper constructed the servo system consisting of PC computer, multi-axis motion control card, servo driver, servo motor and load and edited the control interface program calling the interpolation procedure, which could realize the simulation control and real time control to servo motors. The compare results show the accuracy of the experiment is higher, and the control interface has such characteristics as visualization, operation easily and so on.
