1、外文资料 The aggregate machine-tool CAD system development and research abstract aggregate machine-tool CAD is in Window 95/98, Wndows under the NT4.0 environment, designs personnels special-purpose CAD system with VC5.0 and the AutoCAD R14 ADS/ARX technology development face the aggregate machine-tool.

2、This software technological advance, performance reliable, function strong, convenient practical, has provided the modernized design tool for our country aggregate machine-tool profession. Key word: Aggregate machine-tool CAD jig CAD multi-axle-box CAD 1 uses the aggregate machine-tool CAD technolog

3、y imperative The aggregate machine-tool is with according to serialized, the standardized design general part and the special purpose machine which composes according to the work piece shape and the processing technological requirement design special-purpose part, belongs to the disposable design, t

4、he disposable manufacture piecework product.Therefore, the design quantity is big, the design work is complex.In the current competition intense market economy, the user to the engine bed technical sophistication, the quality reliability as well as the goods supply cycle all requests very high, but

5、guaranteed these many factors the key is the design. In the past that backward manual design method has not been able to satisfy the product design the request, uses the CAD technology, throws off the chart board, has become the current technological revolution the tidal current, imperative. 2 aggre

6、gate machine-tool CAD the application present situation Overseas aggregate machine-tool CAD technology research starts the comparison early.At the beginning of the 70s, some industry developed country first starts in the multi-axle-box CAD aspect to study. Has entered since in particular for the 90s

7、, along with the computer technology development, the interactive cartography and the database management system and so on the development and the application, causes the aggregate machine-tool CAD technology day by day practical also the use scope expands unceasingly, the developed country has used

8、 the CAD technology generally in the aggregate machine-tool design.At present, to CAD/CAM integrative system development. In recent years, according to us to American several main engine bed factories (BURGMAST, KINGSBURY, companies and so on INGERSOLL LAMB, CINCINNATI, MILACRON, CROSS) the understa

9、nding, its CAD technology obtained the universal application. In which most noticeable is INGERSOLL Corporation has 50 interactive CAD workstation composition software and hardware environment, caused it to realize nearly 100% CAD. On the domestic machine tool design portfolio using CAD understandin

10、g earlier. The beginning of the 1970s, Dalian Machine Tool Institute portfolio started on the research in this area of work. 1978 state as a combination of mechanical CAD machine industrial projects, and instructed the ShanghaiJiaotongUniversity. Dalian Machine Tool Institute portfolio, a ministry o

11、fficial in charge of the Institute of Automation, Dalian Polytechnic University, Qinghua University, Beijing University of Technology, Shanghai Institute of mechanical and electrical products and other units to participate in the drilling machine CAD combination of research, This raised our portfoli

12、o Machine CAD technology in the district. After 10 years of efforts and achieved initial results. However, the combination of machine CAD system is 12-27 in VAX II and Micro VAX II on the development, hardware investment, which is difficult to use. By the time the hardware and software environment f

13、or the restrictions, narrow scope of application software, users inconvenient. 3 Development portfolio dedicated machine CAD system software CAD technology is the contemporary electronic information technology an important component of , CAD technology to be commercialized as the most important high

14、-tech industries. The supporting software and hardware, on the basis of different industries, different professions secondary development software, developed for the industry, The dedicated professional commercial software can not only make good economic returns, but will make significant social ben

15、efits. Ninth Five-Year Plan period state auto industry as a pillar industry of the national economy, for the industry to provide a combination of technologies and equipment to machine tool industry to develop rapidly. Along with the development of the auto industry, machine designed to enhance portf

16、olio quality, shorten the design cycle has become an extremely urgent task. Combined Machine CAD technology and can shorten the design cycle and improve design quality, enterprises in the sector improve its competitive edge, enterprises will bring about significant economic benefits. Dalian is China

17、s important industrial base, as a combination of Machine Tool Industry Technology and DevelopmentCenter in Dalian Machine Tool Institute portfolio, industry should play the leading role for the realization of design automation, enhance technological innovation and product competitiveness. promoting

18、our portfolio machine design standards, as soon as possible combination of machine tool industry to provide factory-functional, flexible operation, with a friendly interface, high technological content portfolio Machine CAD software. 4 software with the technical basis for the development of microel

19、ectronics Technology, computer performance has been greatly improved. P II has now dominated the market, P III began listing its CPU performance has been close to the years before the target workstation. Foreign CAD software to the PC Window95/98, Windows NT transplant, such as Pro / Engineer, I-Sui, such as CADDS5. Computer Graphics Accelerator in improving performance,
