Wall Milling Machine Cnc System Hardware Structure Of The Research And Development

With the rapid development of the technologies of the computer, the electronics and the modern control, It becomes more and more necessary to develop the CNC system cheaply and quickly with these advanced technologies. Based on this principle, the plate miller CNC system has been developed. The system, which is called the distributed- dual-CPU structure, adopts the industry PC(IPC) and the programming multiple-axis controller(PMAC); IPC and PMAC are the control center of the system. In the meantime, I/O unit, servo unit and A/D unit are added to the PMAC, and in this way the design of hardware structure of the CNC system has been made. On the basis of the hardware structure, some researches are made as follow: the design of control unit, control panel and control circuit; the choice of servo system control mode; the structure design of interface; the reliability analysis of system and measures which enhance the reliability; the choice of electrical unit. The feasibility of the CNC system has been fully proved in practice.
