The combination of metal cutting theory, computer technology and expert knowledge was used to study the use of knowledge-based engineering (KBE) for cutting large containers. This report includes information on the acquirement, expression, and inference and management of KBE. The structure of the KBE system was established by selecting the principles of processing parameters and optimizing the model of machining data and by using the method of expressing knowledge of combining producing type with frame type and by using the software SQL server 2000. The inferential mechanism of every functional module in the system was realized by applying the software, VC++ 6.0. The KBE technology will help technicians to share expert knowledge and experience, and to optimize cutting parameters to intellectualize cutting design and machining.
