Characteristic Identification Methodology for 2D Sheet Metal Components

Abstract

In the computer-integrated production environment, computer-assisted process planning is a key area which analyses the Computer aided Design server collects information about design and converts it into the necessary information about manufacturing. To identify 2D sheet shearing operations from the nested architecture provided by a wire frame template, a feature identification procedure has been suggested. Basically, the method uses geometric data to determine different groups of objects. Entity groups are categorized into a number of features for raw resources, a set of boundary features, and a set of interior features. There seems to be a special classification of the feature functions inclusion to both the set of boundary functions. Components (i.e. boundary elements set together with their inside feature set components) are lexicographically arranged. Based on the suggested categorization for shearing practices and using multiple feature sets, processing features were defined. The technique listed above, definitions are explained along with its principles. This is performed in the C environment and from the DXF output directory of AutoCAD geometric information is retrieved..
