Most mold workshops coexist with ordinary machine tools and CNC machine tools

April 12, 2023

With the widespread use of CNC machine tools and the deepening of the application of CAD/CAM technology, how to connect the CNC machine tools in the mold shop with the computer, implement integrated digital control to form a distributed CNC system, CAD/CAM integration and computer-aided production management integration. One of the key technologies urgently needed to be solved. DNC can significantly improve the production organization and management of the workshop and improve the utilization rate of CNC machine tools. It has been regarded as a simple, practical and important way to automate the mold shop. Compared with FM S, it is more focused on information flow. Integration, with small investment, quick effect, a large number of interventions in human-computer interaction and good flexibility, so it is particularly suitable for promotion in China's machinery manufacturing enterprises. Due to historical reasons, the mold shop often has many types of CNC machine tools. The CNC system of these CNC machine tools has various grades and models due to different production years and production countries and manufacturers. In addition, most of the mold workshops have common machine tools and CNC machine tools, and the layout is relatively scattered. The layout of CNC machine tools is scattered. The problem of long-distance signal transmission must be solved when networking. At the same time, there are many power equipments in the mold processing workshop, the interference generated is relatively strong, and the frequency band is also wide. Therefore, the communication system should have strong anti-interference ability. When the machine tool is far away from the central computer room, it is necessary to consider setting up the necessary DNC data terminal or intelligent interface in the far processing area due to the inconvenience of the machine operator and the computer room management personnel. For the machining of complex molds, when the NC program is large, it cannot be fed into the machine at a time. In this case, the real-time machining method for transmitting the NC program while machining must be satisfied. (Finish)
