Telegraphen- und Fernsprechtechniknew generation CAD system. It focuses on concurrent design support, product modeling, design parameters inheritance and information propogating among different hierarchies of an integrated design process. A prototype of a CACD system for plastic encapsulation mold is implemented at Shanghai Jiao Tong University to demonstrate these new features.

https://doi.org/10.1007/978-3-642-97799-2-D objects numerically. Various examples of concave polyhedra for determining similarities have been tested. The results show that the theoretical considerations are reasonable and matches with our feeling.

Tasks Facing the Manufacturing Industry and NEC’s Production Innovation cut manpower requirements, narrowed leadtimes drastically, and greatly reduced materials in process. We are now committed to the goal of building information systems that takes full advantage of the IT (information technology) concept to achieve an optimal production system encompassing the entire flow of supply, from planning to scrapping.

Tastdrosseln und Frequenzwandlerlete solids that lack some faces and thus have no volume. The size and position dimensions of the boundary features are presented and managed with a constraint system that is attached to control the geometry information of the boundary representation model. A small prototype system has been implemented to demonstrate the suggested approach.

Telegraphen- und FernsprechtechnikAn explicit semantics representation scheme has been developed to represent deep models of features. A deep model improves the reasoning capability of the mapping process so that the identity of a feature can be established more effectively.
