Process planning is the sister problem of tolerancing. It involves the selection of machine tools and processes that economically yield products within the specification stipulated by design engineers. In this paper, we develop an analytical approach for process planning to achieve the specified tolerance limits of products. The analysis considers a multitude of aspects that are central to successful production. Process capabilities of various machine tools, different cost drivers, and acceptable design limits of the products are among the factors included in the analysis. In addition, the proposed scheme addresses the possibility of reworking the portions that are out of the specified limits. The practice of reworking has proved its efficiency in today's competitive manufacturing environment. A major objective of the work is to choose suitable machining strategies, processes or sets of processes, and the proper sequence of operations to optimize production plans. Furthermore, the results can be utilized to improve the performance of existing decision support systems or develop new ones in this area.
