Especially during the transformation and upgrading of China's industrial structure in recent years, intelligent manufacturing has gradually become the new direction of manufacturing industry development. From the perspective of manufacturing industry, it belongs to an industry that is highly dependent on science and technology. Especially in today's rapid development of science and technology, the mechanical manufacturing industry explores the potential of manufacturing industry by researching and developing new technologies, applying new equipment, etc. As a cutting-edge product of the birth of scientific and technological development, the application of machine tool numerical control technology in the manufacturing industry has further promoted the level of intelligent construction in the manufacturing industry, which has brought a good foundation for the production and development of China's manufacturing industry. In this regard, the article analyzes the application strategy of CNC technology in intelligent manufacturing.展开更多

The system＇s external interfaces are coincident with the corresponding international standards, and the internal interfaces follow the open modular architecture controller （OMAC） agreement. In the research and manufacturing process, object-oriented technology is used to ensure the openness of the HITCNC, and static programming is applied in the CNC system according to the idea of modularization disassembly. The HITCNC also actualizes real-time and unreal-time modules adopting real-time dynamical linked library （RTDLL） and component object model （COM）. Finite state ma- chine （FSM） is adopted to do dynamically modeling of HITCNC. The complete separation between the software and the hardware is achieved in the HITCNC by applying the SoftSERCANS technique. The application of the above key techniques decreases the programming workload greatly, and uses software programs replacing hardware functions, which offers plenty technique ensures for the openness of HITCNC. Finally, based on the HITCNC, a three-dimensional milling system is established. On the system, series experiments are done to validate the expandability and interchangeability of HITCNC. The results of the experiments show that the established open architecture CNC system HITCNC is correct and feasible, and has good openness.展开更多

The sculptured surface is approximated by a regular mesh ofquadrangular facets. A set of equidistant horizontal planes are assigned to intersect the blank ofmachined part and surface model , resulting in a series of contours, which demarcate the feasiblecutting regions of each layer of material removal. The desired cutter path is computed through NCprogramming and any gouging between the cutter and the part being machined is detected and correctedautomatically. The proposed algorithm successfully solves the problem of layered milling forsculptured surface with nested islands.展开更多

The practice teaching link is relatively weak, which is not conducive to students' future job demands. Based on practical teaching problems, this paper implements teaching integration and puts forward purposeful and targeted improvement strategies aiming at the existing problems, which lays a theoretical basis for improving the quality of practical teaching and provides reference for related research.展开更多

Based on this, a part with high precision and special shape is selected as a case. In-depth analysis of its structure and accuracy, scientific and reasonable formulation of the processing technology, at the same time, the complete involvement of special tooling and fixtures, so as to ensure the simplification of parts processing, and thus ensure the processing progress. At the same time, in order to effectively control the quality based on the accuracy and shape requirements of the parts themselves, if ordinary inspection equipment is applied, the purpose of inspection cannot be achieved. Therefore, according to the actual situation, special inspection tools should be designed to ensure the reliability and efficiency of the inspection. Based on this, this paper mainly analyzes and discusses the NC machining process analysis and testing of precision special-shaped parts.展开更多
