The document discusses product and service design prints, computer aided process planning (CAPP), and the variant and generative approaches to CAPP. It defines product and service design prints as defining the characteristics and concepts of products and services. It then defines CAPP as using computers to assist process planners in determining the methods to manufacture parts from initial to final form. The variant approach selects generic process plans using group technology codes, while the generative approach automatically synthesizes process plans without human intervention using databases and knowledge bases.
