Problems solved by technology

An edge, which side it is located on, and what type it belongs to, usually requires manual judgment, which is a lot of work for developers and prone to errors, so it is particularly important to automatically identify the type of edge of a sheet metal part important

Embodiment Construction

[0011] Such as figure 1 Shown is a system architecture diagram of a preferred embodiment of the system for automatically identifying the type of edge of a sheet metal part according to the present invention. The system mainly includes a monitor 1 , a host 2 , a keyboard 3 and a mouse 4 , and the host 2 includes a mold design unit 20 and an automatic identification unit 21 . Wherein, the mold design unit 20 is a mold automatic design software (such as Pro / Engineer), which is used to generate various sheet metal part graphics in the mold design. The mold design unit 20 includes a graphic database 30 for storing the sheet metal part graphics generated by the mold design unit 20 and the attributes of each sheet metal part graphic. The attributes of the sheet metal part graphics include edges included in the sheet metal part graphics, faces adjacent to each edge, and the like. Each face and each edge has its own identifier, through which a face and an edge can be uniquely identif...

Abstract

The invention discloses a system and a method for automatically identifying the category of a sheet metal part side. The method includes the following steps: one pointed side of the graph of the sheet metal part is selected; two neighboring surfaces of the pointed side are obtained; if one neighboring surface of the pointed side is arranged on a base level, then the pointed side is identified to be the side of the base level; if one neighboring surface of the pointed side is arranged on a deviation surface, then the pointed side is identified to be the side of the deviation surface; if the two neighboring surfaces of the pointed side are on a side surface, then the pointed side is identified to be the side of the side surface. The invention can be used for automatically identifying the category of the sheet metal part side and improving the design speed of a product.

Description

technical field [0001] The invention relates to a system and method for automatically identifying the type of edge of a sheet metal part. Background technique [0002] In the secondary development using the mold design software Pro / Engineer, the access of sheet metal parts is generally from the surface to the contour of the surface and then to the edge of the contour, or through the feature (that is, the method of creating a three-dimensional part) to the surface of the feature and then to the side of the face. A body is composed of faces, and there are no special rules between faces. The access and recognition of faces often requires the help of edges related to faces. In actual development, faces and edges are often visited, so it is necessary to Do some analysis and induction on the edges, so that it can form some edges with the same characteristics. In order to achieve rapid and accurate acquisition of some geometric features with the same attributes during development...
