1、The development and characteristics of woodworking machinery The early 21st century, machinery manufacturing industry is characterized by the development of modern high-tech utilization, the trend is four modernizations: the flexible, agile, intelligent, and information technology. Is no longer in t
2、he 20th century, 20 to 40 years developed a mechanical discipline its success - and other mechanical cam-based, using special tools, fixtures, cutting tools, measuring the composition of the flow-type production line - rigid automation. The disadvantage is that rigid automation seriously affect the
3、upgrading of products and impede the adoption of high-tech products uncompetitive in the international market. At present, Chinas machinery manufacturing industry, a number of state-owned enterprises are losing money, Competitive products in the domestic and overseas markets, the product backlog, in
4、 addition to the management system and operation of foreign, and businesses with obsolete equipment, engineering and technical personnel have great knowledge of the relationship between aging. In order to adapt to the market economy, to revitalize Chinas machinery manufacturing industry, it is neces
5、sary to re-understanding of machinery manufacturing industry, understand the current international machinery manufacturing and machinery manufacturing industry in early 21st century, the characteristics and future trends. Manufacturing technology is the backbone of economic development in the 20th c

Business produ
7、ctivity in various countries of the composition, manufacturing technology, the role of the general account for 55% 65%, Japan and Asias four little development in a large extent, with their emphasis on manufacturing technology. These countries and regions around the world attach great importance to
8、high-tech patents will buy it back, through the manufacturing technology, The formation of unique, special, high product, the first to occupy the world market. This is the reason they can rise off the know-how. Machinery manufacturing industry to be the leading information science, materials science
9、, to transform itself； the other hand, information science, materials science, must also rely on manufacturing technology to achieve new development. For example, in the development of computers, the most crucial issue is the high density large-scale integrated circuits and memory device production,
10、 they are dependent on manufacturing technology development. The United States, Japan and other countries experts have manufacturing science and information science, materials science, biological science together with as the four pillars of the contemporary era of science. The United States due to t
11、he lack of manufacturing in recent years, the importance of science, so many of their products uncompetitive. To this end, the U.S. government has approved the Advanced Manufacturing Program in 1996 as the sole focus of the national budget to support scientific and technological areas, which has cau
12、sed the United States, Japan, and Europe in the new round of competition in manufacturing technology. To re-understanding of mechanical manufacturing industry, still contains another sense. It is not in the traditional sense of the machinery, the so-called machining. It is a mechanical, electronic,
13、optical, information science, materials science, biological science, laser science, management and the latest achievements in integrating a new technology and new industries. Detection technology is the development of modern machine manufacturing technology a fundamental guarantee for automated prod

There is no reliable test would be no modernization and automation, not to mention high eff

In this annual meeting, the few articles about the new developments in assembly systems, in both papers stressed that in order to meet the needs of flexible automation, robot vision system must be able to install parts of the body and gestures to identify, should be installed Th

At present machinery manufacturing industry is characterized by the development of comprehensive utilization of high-tech industries in developed countries in many scholars and experts talk about the production process in the flexible, agile, intelligent,
25、 information-based, they all pointed out that the machinery manufacturing engineers should master and comprehensive utilization of engineering mathematics, laser science, laser-electronic technology, computer technology, cybernetics, biology, materials science, management science, humanities and sci

Human beings should not only get rid of the heavy manual labor, but also from the tedious calculation, analysis and other mental freed in order to have more energy to engage in high-level creative work. Intelligent promote flexible, which allows the production system has a better judge and adaptability. The 21st century, will continue to accelerate the upgrading of products, various needs
