This paper presents a new approach, together with its technical implementation, to solve this problem, and discusses web-based study on RP data processing techniques. At present STL files produced by 3D modeling systems contain triangular facet representation of surfaces and have become standard data inputs of RP and manufacturing systems. The paper proposes algorithms for correcting common errors, and optimizes the algorithm of gaps or hole errors leading to open loops in the data structure based on analyses of the rules and errors in the STL file. In addition, effectiveness of the approach is demonstrated by a simple model view example of STL files based on Java 3D technology.展开更多

But it is not enough to perform the complication of PDM in enterprises. Then the mechanism to harmonize all kinds of information and process is needed. The paper introduces a novel approach to implement the intelligent monitor of PDM based on MAS (multi agent system). It carries out the management of information and process by MC (monitor center). The paper first puts forward the architecture of the whole system, then defines the structure of MC and its interoperation mode.展开更多
Product Lifecycle Management (PLM) is a business strategy beginning to gain wide acceptance. Concerning the implementation of PLM projects, six success factors are presented and analyzed in details in this paper.

This paper describes the design of tension controller with electronic gearing. A control algorithm of PID is also introduced in order to improve performance of the tension controller. Finally, experimental results and conclusions are given.展开更多

The employee's ability to learn is bounded, and thus limited. Looking at a modern production system, it is often a complicated array of technologies that have to be coordinated; or the technologies are coordinating themselves through artificial intelligence. This paper discusses the need for a holistic knowledge management approach to manufacturing,combining in-place technology with process management philosophy, in order for the firm's human resources to create, share, store and apply new knowledge.展开更多
