Reconfigurable manufacture system is to list as one of key technologies which will first solve in the future manufacturing, this article will mainly solve research on theory of reconfigurable for NC machine tool. Reconfigurable machine tool has many merits that include modularization, integration, custom-made, convertibility and so on. That is the traditional machine Tool cannot compare. This article...
Digital factory is a new technology to construct a virtual plant framework to integrate manufacturing process planning with manufacturing execution. Object-Oriented technology is introduced to simulate complicated discrete production system. And a virtual factory is constructed in digital environment. In this paper, manufacturing resource library is built to manage manufacturing equipments and all...
Digital factory is a new technology to construct a virtual plant environment to implement integration between process planning and manufacturing execution. Object-oriented technology is introduced to simulate complicated discrete-events system with constructing four basic objects including product, process, planning and resource in digital factory environment. Especially manufacturing resource library...
Topology and weights are closely related in weighted complex networks and this is reflected in their modular structure. We present a complex parts network model based on weighted complex network theory that the nodes are parts of the product, the edges are engineering change transfer relations of the parts, the node weights express the complexity of the parts and the edge weights express the connection...
Computer simulation of the solidification process is used widely in the design of the mould and the die configuration. In this work, a simple and efficient methodology is proposed for the numerical simulation of displacement field for investment casting. The heat-transfer behavior and the time-dependent heat transfer coefficient between a casting and mould are investigated by inverse heat-conduction...
According to the noise properties and the serial slice image characteristics in cone-beam computed tomography (CBCT) system, an adaptive filter for serial slice images of CBCT was proposed. The judging criterion for the noise is established firstly. All pixels are classified into two classes, one is the pixels which are corrupted by Gauss noise and the other is the pixels corrupted by impulse noise...
Pneumatic drying process of ore concentrate is a typically complex industrial process, which involves the theory of gas and solid flow, heat and mass transfer and drying kinetics. There are a large number of factors affecting the pneumatic drying process. As a key parameter of the drying process, the water content of the dried ore concentrate has effect on the stable operation for the smelting process...
Considering that industrial design (ID) processes are full of fuzzy, uncertain, dynamic and changing information, the traditional computer aided methods cannot work well. Based on ID, fuzzy theory, and aesthetics principles, the authors discuss the idea of driving the design process by semantics words. In the process, they attain customers' performance in term of semantics words, built some fuzzy...
