Abstract: A forming die with a flexible blank holder is provided. The forming die includes an upper die set, a lower die set, and a blank holder with a flexible pad. The upper die set has an upper die base and an upper die insert provided on the upper die base and has a cavity surface. The lower die set has a lower die base, an elastic member on the lower die base, and a lower die punch on the lower die base. Guide posts are provided between the upper die set and the lower die set to define relative positions of the two die sets. Through relative movement of the upper and the lower die sets, a blank placed on the blank holder there between is formed by forming. During the forming, the flexible pad is tightly pressed against the blank under the pressing force of the elastic member.

In the present invention, a design knowledge base, a functional feature library, a functional feature module and a graphic user interface can be utilized optionally. Moreover, the present invention can be implemented on the Windows XP system through a commercial CAD software and an API.

Abstract: The present invention discloses a method for recognizing features of a 3D solid model which particularly performs geometric form features. First, the main and minor geometric features of the solid model are respectively defined and sorted into classes and subclasses according to hierarchical taxonomies, and a database of structural features of the solid model is built with respect to a designed table schema. Then feature names and information are retrieved from the structural feature tree of the solid model on the basis of CSG (constructive solid geometry) by means of the “retrieving feature tree information” technique, and decomposed into geometric data and topological data which are finally stored into the database. The method of the present invention can therefore rapidly recognize the features of the solid model with high accuracy.
