CNC machining center using computer control, can ensure the production of machined parts with a strong precision accuracy. However, in order to get a better role, the signal input to the controller to go through a series of processing, it is difficult to avoid the loss of frame, Ting time. Therefore, the CNC centering machine manufacturer in high speed production processing, to maintain strong production processing accuracy must be used to reduce the loss of frame, time. High precision, high speed production processing, in addition to mechanical structure design and manufacturing to ensure that the goal can be achieved, the main requirements of the CNC system is a fast response time, high control accuracy.
CNC system is an important function of the CNC machining center system software is because of this function, the production process makes (MT) greatly forward development trend. Fastener CNC machining using feedforward control control to pay out the difference caused by the servo motor lagging behind, to improve the production processing accuracy. Proper control of the feed rate and the use of moderate acceleration and deceleration trend graph can reduce the difference caused by acceleration and deceleration lag. The "look-ahead" control calculates, processes and caches the fitness movement information data in 2 segments before the program execution, so that the CNC tool can be controlled to move at Kor speed and the difference is not large.
