Feature modeling technology is the requirement of Advanced Manufacturing Technology (AMT). It is one of the key technologies of CAD/CAPP/CAM integrated system to build a shared part feature model. A feature modeling system can provide not only the geometry information of a part, but also the processing information of the part, which is needed by the latter CAM system, to realize information share and exchange between CAX systems. In the paper, feature concept, feature classification, model structure and modeling method based on features are introduced. Then, an interactive feature modeling method is presented. According to the requirement of CAPP, the system developed can supply the processing information to generate the corresponding manufacturing feature model that can be output in XML file format for a CAPP system.

Abstract Network and Internet technology open up another domain for building future CAD/CAM environments. The environment will be global, network-centric, and spatially distributed. In this paper, we present Web-enabled feature-based modeling in a distributed design environment. The presented approach combines the current feature-based modeling technique with distributed computing and communication technology for supporting product modeling and collaborative design activities over the network. The approach is implemented in a client/server architecture, in which Web-enabled feature modeling clients, neutral feature model server, and other applications communicate with one another via a standard communication protocol. The paper discusses how the neutral feature model supports multiple views and maintains naming consistency between geometric entities of the server and clients as the user edits the part in a client. Moreover, it explains how to minimize the network delay between the server and client according to dynamic feature modeling operations.

Providing advanced 3D interactive facilities to users of a client-server collaborative modeling system presents a great challenge when thin clients are involved, mainly due to their lack of both a full-fledged CAD model and adequate modeling and solving functionalities. This paper presents a new approach that provides a convenient representation of feature model data suitable for direct manipulation of feature models at such clients. In particular, feature handles are proposed to support interactive feature editing. This approach combines all advantages of a thin client approach with the sort of 3D direct manipulation facilities usually only found in powerful standalone CAD systems.

Open Die Forging

A virtual plant, built in a computer by using computer graphic (CG) and Virtual Reality (VR), can model the precise and whole structure of an integrated manufacturing system and simulate its physical and logical behavior in operation. This paper aims to reveal the advanced modeling and VR realization methods in developing a virtual forging plant for automatic and programmed open-die forging processes. Two sub-models, component model and process model, compose the overall modeling architecture of a virtual integrated open-die forging plant. The coordinated motion simulation of the integrated system is realized through a kinematic modeling method. A compound stiffness modeling method is then developed to simulate the mechanical behavior in operation. The process simulation of the virtual plant is conducted on the basis of the above two modeling methods. A practical application example of virtual plant for integrated open-die forging process is presented towards the end.

A generative automotive engine CAPP (Computer-Aided-Process Planning) system based on Oracle database was developed. A practical tolerance information communication solution between the CAD and CAPP system was proposed and realized in an independent file schema. A parametrical cylinder head model based on manufacturing feature was created to meet the requirements of the CAPP system feature recognizing. The data structure of the tolerance information in the Pro/ENGINEERING database was presented. A Pro/TOOLKIT program was developed to extract the model’s tolerance information automatically. The tolerance information extracted was then organized with EXPRESS language and imported into the CAPP system database Oracle.

Important Research Topic

Semantic feature modeling is an important research topic in CAD, in which geometric constraints in model are solved automatically. A semantic feature modeling method is given in this paper. Firstly, the feature dependent graph is built based on geometric constraints. Secondly, the feature dependent graph is decomposed according to the complexity of subgraphs and the whole problem of solving geometric constraints is divided into several small ones. Thirdly, these small problems are solved. At the same time, the modeling architecture based on the decomposition of feature dependent graph is given. Experimental results show that when the proposed method is applied, the modeling performance is improved.
