Chapter 1 Advanced Manufacturing Technology (AMT) 先进制造技术双语教学课件-HTC

• The nature of competition in manufacturing has changed. High-quality and highly customized goods are demanded. There is a premium for being the first to market with a product. This has created a demand for "hard" and "soft" technologies that help shorten design and production cycles.
• Vision systems provide, in real time, monitoring for precision machining and highspeed printing and remote handling of mining equipment used thousands of metres underground.

Advanced Manufacturing Technology (AMT)
PREFACE
• Manufacturing
• Manufacturing (from Latin, "making by hand") is the use of tools and labor to make things for use or sale.
• The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial production, in which raw materials are transformed into finished goods on a large scale.
• Free trade has increased the breadth of geographical competition, making it easy for foreign manufacturers to enter the Chinese market and for Chinese firms to enter foreign markets. The source of this competition varies, some of it from low-wage areas and some of it from very technologically sophisticated countries.
Manufacturing technology has developed for many years. Over these years, it has gone through many changes and progressed the following stages: 1.Befor 1770: craftspeople with anvil（铁砧） and hammer（锤、榔头）.

• The hardware technologies have found wide acceptance in discrete manufacturing and in resource and processing sectors. Computer numeric controls have been applied to systems for machining, forming, cutting and moulding. The accuracy, speed and control of robots have improved significantly and, as a result, they are used extensively in welding, painting, material handling and an enormous number of unique assembly applications.

• Technology is the process by which humans modify nature to meet their needs and wants.
• Advanced manufacturing technology
• AMT involves new manufacturing techniques and machines combined with the application of information technology, micro-electronics and organizational practices within the manufacturing process.
• Manufacturing has been influenced by trade liberalization, global competition, market fragmentation, technological innovation and the demands of more sophisticated consumers, in response to these pressures, manufacturers are incorporating more flexibility and technology in their production practices. These features have become a trade-mark of world-class corporations. AMTs are a key enabler for firms attempting to meet world-class performance targets.
• Manufacturing practices and processes have come under increased pressure from global competition. Demands for improved customer service, breadth of product line, improved quality, quick response and a much shortened time-tomarket for new product introduction cannot be ignored by firms. In the face of these intense pressures, manufacturers around the world are moving away from mass production manufacturing processes. They are turning to greater flexibility and speed in manufacturing practices. These practices have become the foundation for "Best in Class" manufacturers and processors.
• Advanced manufacturing technology is a modern method of production incorporating highly automated and sophisticated computerized design and operational systems. AMT aims at manufacturing high quality products at low cost within the shortest delivery time. Advanced manufacturing technology is typically reflected by the achievements in high precision and sophisticated automation manufacturing operations.
能化则体现了自动化的深度，它不仅涉及 物资流控制的传统体力劳动自动化，还包 括信息流控制的脑力劳动的自动化。
• Complementary to the hardware technologies of AMTs is a wide range of "soft" manufacturing process technologies. Just-in-time (JIT) manufacturing, total quality management (TQM) and supply chain management are but a few of the many "soft" AMTs adopted by manufactures and processors globally.
• Computer-aided design (CAD) and rapid prototyping have substantially shortened the development time for new products.
• Computer-integrated manufacturing (CIM) is applied in machine shops for tool building, the production of engines and body assemblies for passenger cars, the manufacture of airplane landing gear and the production of hypodermic needles for the medical devices sector. CIMS是英语
