4 Development of a visual environment system based on object-oriented virtual flexible manufacturing system

Based on the previous research, combined with object-oriented technology, Opengl modeling, computer simulation, multi-clock technology, data decoding and data protocol development, CAD technology, computer graphics, CNC machine tools and CNC machining, flexible manufacturing systems, manufacturing processes Learning a variety of knowledge and technology, in the VC++ development environment, compiled a virtual flexible manufacturing system modeling, motion simulation visualization system, the system can obtain different processing simulation effects for different process models, different equipment layout, Thereby obtaining different processing schemes for the same part. In order to obtain a satisfactory processing plan and model. The system is slightly expanded. It can become an immersive system based on desktop virtual reality, thus increasing the subjective evaluation of people. Get a deeper understanding of the system itself.

In addition, the project has done a lot of detailed work on the modeling and visualization of numerical control systems, and has direct or indirect guidance on some of the theories of virtual prototypes, virtual manufacturing systems, and virtual reality.

In short, the project has achieved satisfactory results in a limited time according to the requirements of the task book. The current part of the research, the research project and the results have the following meanings:

(1) Exploring the intrinsic nature of manufacturing systems and theoretically modeling the complexity of manufacturing systems to understand the decisive factors affecting manufacturing systems;

(2) Aiming at the problems existing in the current manufacturing system. Establish a manufacturing program evaluation system to correctly assess market risks, and find problems by the evaluation system as soon as possible before the problem occurs, thereby improving the ability of products to respond quickly to the market;

(3) Adopting visualization technology and timely combining virtual reality technology to consider people in the entire manufacturing system evaluation system to increase the subjective initiative and enthusiasm of the input system, so as to increase human intelligence and experience in the entire evaluation system, faster Find problems and get satisfactory results;

(4) Combine computer simulation, computer graphics, virtual reality and other technologies with manufacturing systems to conduct cross-disciplinary research and improve the research advantages of this major.

Because the research of this project is more and more difficult, the research cycle is shorter, and the cutting mechanics model test equipment department is needed. In order to obtain the overall effect of the project, the project weakens the establishment of the machining mechanics model. This has no effect on the overall effect of the virtual flexible manufacturing system, but has a certain impact on the processing of a certain process of the machine tool. Therefore, the subsequent work will be based on the detailed modeling of the virtual manufacturing process model, taking into account the cutting depth, cutting thickness, cutting speed, tool angle and other cutting factors as well as the physical model of the machine itself, and the cutting mechanics model, and for cutting Visualization of the process for material removal simulation. To gain an in-depth understanding of the nature of virtual manufacturing systems.

Night vision telescop

The night-time external sight with the image intensifier as the core component does not use infrared searchlights to illuminate the target, but uses the light reflected by the target under weak illumination to be enhanced by the image intensifier on the fluorescent screen to a visible image that can be perceived by the human eye for observation and aiming Target.
