Research on integrated reverse engineering technology for forming sheet metal with a freeform surface

This paper presents a model of an integrated reverse engineering system and sets up its various-data-output flowchart, which is easily associated with other systems. The ideal of integrated reverse engineering is introduced to the system of forming sheet metal with a complex surface, and using the IDEF0 method sets up the function model of the system. The freeform surface reconstruction and CAD modeling of the system are described and discussed. This paper discusses some problems, such as the feature expression, feature modeling and feature translation of the sheet parts and dies.
