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
