Embodiment Construction
[0053] The present invention will be further described below in conjunction with accompanying drawing.
[0054] In this embodiment, the hardware platform adopts full digital control mode, standard industrial grade IPC board card, PM-1GHz CPU as the numerical control system controller, and the axis adopts MECHATROLINK bus control mode. The open numerical control system developed on the basis of this platform is an integrated numerical control system, giving full play to its characteristics of fast calculation speed and powerful functions, and completes functions such as display, interpolation calculation, and motion control through software. In this CNC system, the motion controller is the core. After adopting the speed forward control method based on filtering technology, the component structure of the motion controller is as follows: figure 1 shown.
[0055] The method of the present invention is based on the acceleration and deceleration characteristics of the filtering tec...
