CNC cutting machine is the material such as rubber, silicone, nitrile by PLC program control, automatic continuous or single cut out the article wants to cut into the distance. CNC cutting machine automation control is to guarantee the precision of the cutting distance, the system’s flexibility, reliable and effective new development request. Starting from the cutting distance control requirements, combined with PLC control system, frequency control of motor speed and the configuration software technology, the numerical control cutting machine control system for related research.First of all, according to the control of the cutting material such as rubber requirements analysis, design and reasonable control scheme, programmable controller and frequency conversion speed regulation technology is presented in this paper for rubber feeding, discharging, cutting process automatic control, configuration software technology to complete the PC monitoring system design, the overall scheme is determined, the choice model of PLC and I/O module, inverter model, touch screen model.Second, respectively from two parts of hardware and software to complete electrical control system design and software design of the control system. Electrical control system respectively from the main circuit, the inverter control circuit and the PLC wiring three aspects to complete the design of the electric control system of the whole system; Software control system, the reasonable design of program structure, process flow diagram, run automatically by PLC language to complete the system control, signal acquisition and motion control of the pulse, the human-computer interaction interface design requirements according to the system, use configuration software EV5000PC monitoring system design, complete the upper machine data display, alarm, display, remote control, etc.On the basis of the completion of the system hardware and software design, structures, control cabinet, complete the components of the electrical wiring, electrical testing and software debugging modification work, meet the requirements of article is expected to cut the distance accuracy control.CNC cutting machine control system design study, can improve the work efficiency, reduce manpower cost, improve the accuracy and cutting speed, greatly enhance the CNC cutting machine in domestic and international market competitiveness.
