The technology of feature classification, feature definition and feature recognition was studied for punch products, and the technology methods of feature recognition, matching, dealing with feature and extracting the feature parameters from the geometry model of progressive die parts were put forward based on component object model (COM) technology. By means of COM programming, the bending and plane geometry feature recognition of blank layout for the car punch parts were completed in blank layout optimization. The research results show that the feature designing and recognition in punch product can be realized in SolidWorks API, and this key technology can offer an effective and simple means in development of knowledge-based engineering system for progressive die.
