This paper discusses various issues in integrated manufacturing planning that establish the need for incremental process planning. Interfaces between process planning and design, facility planning and scheduling modules are explained in order to verify that process plans are developed afcer receiving a feedback from other manufacturing planning systems and justify the need for incremental process planning. An experimental process planning system that provides for incremental planning is described and its modules explained. The control structure that enables incremental process planning for various changes in product design and manufacturing environment is discussed and appropriate process plan representation is suggested.
