Abstract: According to the effective expression and management requirements of Three-dimensional Computer Aided Process Planning(3D-CAPP)system for the process information,a method to achieve to express and manage the process information simply and efficiently by using working procedure model was proposed.The process information of machining were analyzed and divided into two types of static process information and dynamic process information.The expression solution of process information was confirmed based on working procedure model definition.The process information was effectively managed by using structural level of process information,and the process manager was constructed for storing and managing the process information.The proposed methods were integrated into 3D-CAPP system and a 3D process model that expressed and managed the process information was constructed to verify the effectiveness of proposed process information expression and management technology.

Key words: working procedure model, three-dimensional process model, process information, 3D-computer aided process planning
