STEP-NC integrates the relevant application protocols of STEP and the manufacturing information of CAX, and abandons the single-line information transmission method of the ISO6983 standard program among the systems. The STEP-NC program establishes product information based on the unified data model to ensure The integration and sharing of data information has promoted the development of intelligent, networked and integrated CNC technology. This paper expounds the relationship between STEP and STEP-Nc, the data model and program structure of STEP-NC, studies the key technology of CNC based on STEP-NC, and gives the simulation simulation processing of STEP-NC numerical control program in actual CAM system. Methods. This paper provides a reference for the in-depth understanding and application of STEP-NC, and the research on STEP-NC integration technology. STEP-NC has replaced the traditional CNC programming interface standard and has become a new standard in manufacturing. This change will have a revolutionary impact on the field of numerical control technology. Not only that, the manufacturing ideas and concepts embodied in STEP-NC will have a major impact on the development of digital manufacturing technology in the network environment and the entire manufacturing industry. Therefore, studying STEP-NC is extremely important. Third, the realization of network numerical control system 1 Network CNC system hardware platform design and implementation The network numerical control system hardware platform is the physical realization platform of the system. The parts are interconnected through the information management network, the commands and data information are transmitted, and the numerical control tasks are completed in parallel. According to the different realization functions of each hardware in the system, the hardware platform can be divided into two parts. The network transmission function module and the numerical control system function module are specifically designed and implemented as follows: (l) Network transmission function module (2) CNC system function module 2 Network CNC system software platform design System software includes real-time operating systems, communication systems, device drivers, and other system programs to choose from, such as database systems and graphics systems. The system software provides services to the application software through the standard application (the API). The textual design of the system software platform is explained from the following aspects. (l) Web server selection (2) Selection of database server (3) Web database process analysis Previous page Heilongjiang Junhe Building Materials Technology Co., Ltd , https://www.junhejiancai.com
