Incremental generation of alternative process plans for integrated manufacturing

by Thiruppalli, Shridharan

Abstract (Summary)
Current developments in computer integrated manufacturing focus on linking different automated activities with the enterprise, in order to efficiently use the information and significantly reduce the production cost and time. The most critical link is the link between design and process planning activity. In addition, shortening the product development cycle and responding to the changed market demand are highly imperative. Traditional CAPP systems operate on a batch mode. That is, process plan is generated for a completed part model. If the part undergoes design change, then the entire process plan network is generated again to accommodate the design change. Instead, if only a part of the process plan network is updated to accommodate the design change, then the process plan is considered to be incremental. The main objective of this research is to develop a computer-aided process planning system. This system establishes a linkage between part design and process planning system, where the linkage helps to generate process plan network incrementally. The process plan network also accommodates alternate process plans depending on the number of process sequences and machines available for features. Focus is mainly established on process sequencing aspect of process planning. Further, the CAPP provides a number of optimal process plan alternatives based on manufacturing cost. This CAPP system has been tested for incremental process plan generation with number of example.
