Title: $Implementation of STEP-NC Manufacturing Feature Recognition Based on Attribute Adjacent Graph
Abstract: Considering the manufacturing features defined by STEP-NC,it clarifies the feature recognition based on AAG and its implementation process.It analyzes file structure of STEP AP203,extracts the geometric and topology information in the file,judges the concave/convex of the common edge,constructs the attributed adjacency graphic and attributed adjacency matrix.Then it deconstruct and match these Sub-feature graphics by using a certain algorithm,develops a software prototype with VS2005.It verifies this feature recognition method.
