Abstract: According to the concurrent effects of product design and process planning, and rules of product information change, a three-phase process planning model including initial process planning, rough process planning, and detailed process planning was proposed. Key characteristics were employed to express rough-granularity incomplete product information and a strategic framework of conceptual process planning was constructed. Moreover, solutions and strategies were proposed to solve the following crucial issues involved in conceptual process planning: product information identification based on key characteristics, multilevel resolution based manufacturing processes classification and selection, extensible core process planning, and producibility evaluation based on variation degree .

Key words: modern product development, process planning, conceptual process planning, core process planning, key characteristics, producibility
