1 grouping technology (GT) grouping technology (GT) reveals and utilizes the similarity between things, classified into groups according to certain guidelines, the same group of things using the same method of processing, in order to improve the efficiency of the technology, known as grouping technology. In mechanical engineering, grouping technology is the basis of computer-aided manufacturing, grouping philosophy for the design, manufacturing and management of the entire production system, change the multi-species, small batch production mode, to obtain the maximum economic benefits.
The core of group technology is a group process, it is the structure, material, process similar parts into a family of parts (group), according to the family of parts to develop technology for processing, expanding the batch size, reducing varieties, to facilitate the use of efficient methods to improve labor productivity. The similarity of parts is broad, in the geometry, size, functional elements, accuracy, material and other aspects of the similarity for the basic similarity to the basic similarity as the basis for manufacturing, assembly and other aspects of production, management, management and other similarities derived, known as the secondary similarity or derived similarity.
2 Agile Manufacturing (AM)
Agile Manufacturing (AM) is a manufacturing philosophy and production model that refers to the realization of agile production and operation by an enterprise. Agile manufacturing includes flexibility in product manufacturing mechanical systems, employee empowerment, manufacturer and supplier relationships, total quality management, and enterprise reconfiguration. Agile manufacturing is the use of computer networks and information integration infrastructure, the construction of a number of enterprises to participate in the "VM" environment, the principle of competition and cooperation, in the virtual manufacturing environment, dynamic selection of partners, the composition of task-oriented virtual company, rapid and optimal production.
3 Concurrent Engineering (CE)
Concurrent Engineering (CE) is a systematic working model for the parallel and integrated design of products and their related processes (including manufacturing and support processes). In the traditional serial development process, problems or deficiencies in the design can only be discovered in processing, assembly or after-sales service, respectively, and then the design can be modified to improve the processing, assembly or after-sales service (including maintenance service). And parallel engineering is the design, process and manufacturing together, using the computer Internet parallel operation, greatly reducing the production cycle.
4 Rapid Prototyping (RPM)
Rapid Prototyping (RPM) is a set of CAD/CAM technology, laser processing technology, CNC technology and new materials and other technical areas of the latest achievements in the integration of parts prototyping technology. It is different from the traditional method of manufacturing parts by material removal, but the way to construct the part model with the accumulation of material layer by layer. It utilizes the 3D CAD model data of the part to be manufactured to directly generate a product prototype, and the CAD model can be easily modified to remanufacture the product prototype. Because this technology is not like the traditional parts manufacturing method requires the production of wooden molds, plastic molds and ceramic molds, etc., the manufacturing time of parts prototypes can be reduced to a few days, a few hours, greatly shortening the product development cycle and reducing the development cost. With the rapid development of computer technology and three-dimensional CAD software applications continue to promote, more and more products based on three-dimensional CAD design and development, making the wide application of rapid prototyping technology possible. Rapid prototyping technology has been widely used in aerospace, aviation, automotive, communications, medical, electronics, home appliances, toys, military equipment, industrial modeling (sculpture), architectural models, machinery industry and other fields.
5 Virtual Manufacturing Technology (VMT)
Virtual Manufacturing Technology (VMT) to computer-supported modeling, simulation technology as a prerequisite for the design, processing and manufacturing, assembly, and other whole process of unified modeling, in the product design stage, real-time parallel simulation of the whole process of the future manufacture of products and its impact on the design of the product, to predict the performance of the product, the product's manufacturing technology, The manufacturability and assemblability of the product, so as to organize the production more effectively and economically and flexibly, and make the design layout of the factory and workshop more reasonable and effective, so as to minimize the product development cycle and cost, optimize the quality of the product design, and maximize the production efficiency. Virtual manufacturing technology to fill the technical gap between CAD / CAM technology and the whole process of production, enterprise management, the product process design, operation planning, production scheduling, manufacturing process, inventory management, costing, parts procurement and other business production and operation activities in the product before the input to be displayed on the computer and evaluation, so that the designers and engineers and technicians in the product before the real manufacturing, through the Computer virtual products to foresee the possible problems and consequences. The key to the virtual manufacturing system is modeling, that is, the real environment of the physical system mapped to the computer environment of the virtual system. The products produced by the virtual manufacturing system are virtual products, but have all the characteristics that real products have.
6 Intelligent Manufacturing (IM)
Intelligent Manufacturing (IM) is manufacturing technology, automation technology, systems engineering and artificial intelligence and other disciplines interpenetrate each other, intertwined and formed a comprehensive technology. Its specific performance: intelligent design, intelligent processing, robot operation, intelligent control, intelligent process planning, intelligent scheduling and management, intelligent assembly, intelligent measurement and diagnosis. It emphasizes through the "intelligent equipment" and "autonomous control" to construct a new generation of intelligent manufacturing system model.
Intelligent manufacturing system has the ability of self-regulation, self-organization, self-learning and self-optimization, self-repair ability, and thus very adaptable, and because of the use of VR technology, the human-machine interface is more friendly. Therefore, the research and development of intelligent manufacturing technology is of great significance for improving production efficiency and product quality, reducing costs, and improving the market resilience of the manufacturing industry, the national economic strength and the national standard of living.
