Knowledge integration in CAD-CAM process chain

ABSTRACT

Many conscious or unconscious decisions of the designer directly sets manufacturing steps. Currently the information for the steps have to be recreated by the production planner. In other cases the manufacturability is not guaranteed. This paper will show, how a manufacturing knowledge integration in CAD systems will support the planning and work preparation. This knowledge is distinguishable between conventional and additive manufacturing. This paper shows how knowledge can be implemented in CAD systems with different integration depths to reuse them in CAM systems. For this, the knowledge will be extracted from structured text files (such as XML files) by an expert system. Another possible source is a database with company and international standards, which can be accessed directly or through a web service. Furthermore the benefits of web services in that field will be analyzed.
