1、郑州科技学院本科毕业设计（外文翻译）题 目 普通X62W铣床的数控化改造设计 学生姓名 李博 专 业 机械设计制造及其自动化 班 级 08级本科（6）班 学 号 200833164 院 （系） 机械工程学院 指导教师（职称） 朱永刚 畅静文（讲师）完成时间 2012年 5 月 16 日 X62W CNC milling machine transformation1 general CNC transformation of the need for analysisOur about 3200000 existing machine tools, the machine tool techn
2、ology status of ageing is serious, according to statistics, about 30% of the total country equipment in more than 16 years, of which nearly 30% of age more than 26 years, all these show the present our country did not go mainly rely on progress of science and technology of machine tools to transform
3、 track. In addition, with the development of science and technology, production is dependent on the degree of equipment increases increasingly, the crop of the enterprise, quality, efficiency, cost, safety and environmental protection and labor emotions get equipment restrict, realize the modernizat
4、ion of enterprise oneself be imperative. But according to the data, our metal cutting machine tool production only accounted for similar equipment to have an amount 1 / 28, such as the annual production of all the machines used to replace the old machine tool needs 28 years so, our country is solved
5、 at present equipment technical progress is the main way of machine tools.2 domestic and foreign research present situationIn todays world, industrial developed country to machine tool industry height seriously, competing for the development of mechanical and electrical integration, high precision,
6、high efficiency, high automation and advanced machine tool, in order to accelerate the industrial and economic development. For a long time, Europe and the United States, Asia in the international market are in fierce competition, has formed an invisible front, especially with microelectronics, comp
7、uter technology, numerical control machine tools in the nineteen eighties later accelerated development, put forward more requirements of all users, had become the four big international machine tool exhibition to display machine tool manufacturers advanced technology, for the user, enlarge the mark
8、et focus. The more famous control system : Japan FANUC series, Mitsubishi series, OKUNIA series, SODICK series, series of Hitachi, Germany SIEMENS series, DECKEL series, Heidenhain series, HELLER series, the United States ALLEN-BRADLEY ( AB ) series, CINCINNANTI series, Num series, FIDIA series of F
9、rance, Italy, Spain, Switzerland FAGOR series, AG series of domestic series.In the United States, Japan and Germany and other developed countries, they will machine transformation as a new economic growth sector, the business scene, is in the golden age. As the machine tool and the continuous advanc
10、ement of technology, machine tools transformation is a timeless issue. Transformation of Chinas machine tool industry, but also from the old to the industry into the digital technology-based new industries. In the United States, Japan, Germany, with machine tool of numerical control technical reform
11、ation and production line has a broad market, has formed a production line of CNC machine tool and the new industry. In the United States, reconstruction of machine tool industry called machine regeneration ( Remanufacturing ) industry. Engaged in renewable industrys well-known companies: Bertsche e
12、ngineering company, ayton machine tool company, Devlieg-Bullavd ( PO ) services group, US equipment company. The United States company has been in China for the company. Rebuilding of machine tool industry in Japan called machine modified ( Retrofitting ) industry. Engaged in refitting industry well
13、-known companies have: Doomsday engineering group, three post machinery company, Chiyoda engineering machine company, Nozaki engineering company, Hamada engineering company, Yamamoto engineering company.Catch up with the pace of computer system structure, accelerate the development of NC system for
14、NC development speed, has become the main trend. The fourth generation computer engineering structure and microelectronic technology as the basis, make full use of existing computer hardware, software resources, development of bus type, module type, open type, embedded on a flexible NC system, which
15、 is suitable for machining complex parts, vertical machine tool with CNC system, but also for future automation upgrades the function may be expanded requirements.China s NC system development has the following 3 features:( 1 ) system of high-grade numerical control technology has been a breakthroug
16、h. As of I type numerical control system, with multi axis linkage function, fast feed speed in 1.67m / s above, have stronger communication, management function.( 2) universal CNC system is a mature technology. Beijing Machine Tool Research Institute BS9l system, these systems are generally equipped with CRT display, can be configure
