OMEGA, AN EXPERT CAPP SYSTEM

This article presents the validation of a part analysis method for the creation of a process-planning system for automobile prototype activi ty at the PSA group. The methodology presented is founded upon the div ision of the problem into two semi-separate sub-fields. The first cons ists of automatically defining the operation sequences of machining fe atures using production rules. The second one defines the sequencing o f machining operations in set ups, founded upon a constraint planning strategy. The methods developed in this article have been implemented as an expert system named OMEGA.
