Abstract


With the development of electron and information technology, the technology sustain have provided for our machine tool equipment modernization. More and more financing and techno log yare plough into the tradition machine for exerting efficiency and prompting precision rapidly, acquire well impression. Now it becomeeficiency approach forcorporation reconstrtlctive, by numeri control system composing PLC module frequency and conversion control and inspecte quipment carry out programe import and automatizatio ncontrol, to reduce trouble and improve efficiency.Boring Machine is the common cold in the use of the equipment it mainly for processing precision, require a higher finish the hole and the distance between each hole demands a more precise components (such as some cabinet parts), a precision machine tools. Mainly used for precision machining parts on the cylindrical hole. These holes of the axis line often requires strict adherence to the parallel or vertical, the distance between each other also requires very accurate. Its original control circuit for the relay control, contact contacts, lines complicated, failures, operators of large maintenance tasks, in order to overcome these shortcomings, reducing the equipment failure rate and improve efficiency in the use of the equipment, the light of this situation, we With PLC control of its relay control circuit.This paper introduces the structure and working principle of the T68 horizontal boring machine. Through the analysis of the T68 horizontal boring machine’s controlling system, design a system of the PLC control circuit, the system input and output, statistics. Selection of Japan’s Mitsubishi company’s FX2N-48MR PLC, the distribution of the PLC I/O address, the external circuit design PLC, identified the PLC I/O wiring diagram. It introduces familiar programmer methods. According to the boring machine control requirements and characteristics set out the logic of algebra show, using logic design methods ladder design. This method is simpler to learn and to use, has higher success ratio, and can save time in designing complex controlling programmer. GX Simulator6-C through a process simulation software to simulate the scene boring machine control simulation debugging, to transform the system requirements and effective operation. By using hardware and software methods, it improves antidisturbance performance of PLC controlling system . Finally, the paper summarized research achievement, discussed soft resue teclmicin research subject combine with autthor’s specialty, prospected the further study in the future.
