Aiming at difficult management and complicated changes of process information in traditional twodimension machining process planning for aeroengine parts

through analyzing characteristics of the mechanical process information

mechanical process information was divided into two types including static process information and dynamic process information. Management system of mechanical process information for aeroengine parts was put forward and designed under 3D environment. The structure and work flow of management system on mechanical processing information were presented. The key technologies of the creation and searching of process repository

integration of process information based on XML and visualization file generation of process planning were realized. Efficiency and quality of process planning for aeroengine parts were improved and lead time of aeroengine parts was decreased effectively.
