System integration is a necessary solution to the database explosion and data silos and is a major trend in the development of web technologies. This paper examines system integration in terms of both breadth and depth, detailing the concepts, methods, typical application areas, and challenges faced by system integration. It also focuses on the most popular SOA-based integration methods. Finally, a summary and outlook on system integration are given.

For a full three-dimensional process design manufacturing technology platform for product collaborative design and process design requirements, this paper introduces a kind of MBD based 3 d technology platform, platform based on MBD technology and knowledge base system, build the information processing technology and the mapping relationship between information modeling, and design the grouping based on the characteristics of the process of the full three-dimensional design process. Under the support of a knowledge base, the platform realizes the optimization of product design and manufacturability inspection analysis and drawing compliance inspection, found that as early as possible in the design of manufacturing related problems, to avoid disconnection between design and manufacturing in the traditional design method and make the design of the products meet the requirements of the product's functionality, manufacturability, etc. It is of great significance for enterprises to implement 3D digital process design and integration technology.

With the continuous improvement of manufacturing industry requirements for product quality and efficiency, given the separation of part design and development and manufacturing, this paper explores the manufacturability analysis system based on process knowledge, and classifies process knowledge into standardized knowledge, structural process knowledge and manufacturing constraint knowledge, and adopts object-oriented process knowledge representation. The implementation method and process of process review of parts by the manufacturable analysis system are described. The two manufacturability evaluation strategies based on rules/planning were studied and analyzed, the process review of the 3D model was carried out experimentally, and the system's feasibility was verified. It improves parts' design quality and efficiency and is of great significance to the design and development of new products in the future manufacturing industry.

In the paper, the automobile auxiliary instrument panel is taken as an example to illustrate the production process, and Flexsim software is employed to establish a simulation model of the production line of automobile auxiliary instrument panel to analyze the bottleneck operation in the production process of the product. Then the production line balance principle and ECRS principle are employed to adjust the production process flow and to reasonably configure machines and operators of the production line so as to improve the production efficiency of the production line.
This paper studies the surface machining path representation based on NURBS and its key technologies of path planning, analyzes the advantages and disadvantages of various path planning algorithms for NURBS surfaces, and finds that the current NURBS surface machining path planning algorithms mainly consider geometric constraints, while There is less correlation analysis on the index of machined surface roughness, so it is necessary to combine intelligent algorithms and other technologies in the future to better solve practical engineering problems. Path planning algorithms are evaluated.
Industrial robots need to perform more complex manufacturing actions. The original teaching programming is gradually replaced by offline programming due to low accuracy, high personnel safety risks, and teaching difficulty. Various offline programming software is studied explore the specific advantages of offline programming compared to teaching programming. Through the research and analysis of robot kinematics, collision detection algorithm, and post-processing in offline programming, the technical differences between dedicated and general offline programming software are pointed out; RobotMaster and RobotArt are used to plan the grinding path offline for workpieces, and offline programming under different technologies is analyzed. The programming process of the software and the characteristics of the generated program, and the prospect of the development of the robot offline programming technology are prospected.
We present multi-exposure compressive in-line holography (MCIH), which applies compressive holography to multi-exposure in-line holograms. Multi-exposure holograms of 4D moving object can be captured continuously at different time by in-line hologram recording setup. A new single hologram is generated by coded multi-exposure holograms uniformly. 4D moving object can be reconstructed by the new single hologram. And then the trajectory of moving object can be tracked, and the location of time-space object can be defined. The method is verified by two experiments. The results of experiments show that MCIH can obtain the time-varying location of moving object.
