Improving computer aided tolerancing by using feature technology

Abstract

The application of feature technology in the field of Computer Aided Tolerancing (CAT) enhances simultaneous engineering during the product development process. The combination of micro-geometrical, topological and other product data within one element enables further integration and processing of tolerance information in different phases of the product life cycle. The designer's functional view can be combined with Design for X information. For example, information about necessary and possible manufacturing processes for a specified tolerance might be attached to the geometry of a workpiece. By using this approach a first choice of manufacturing machines or information about necessary and possible inspection-methods could be achieved.
