This paper develops a 3-D numerical simulation model for the epoxy casting process including the filling and curing stages. A lot of factors are considered in the model, such as the resin flow, heat transfer, curing reaction, viscosity variation and gravity. The CCD is used to record the flow front advancement during the filling course through a glass window, and some thermocouples are applied to ...Show More
Because of the complex geometry shapes and structures of mould cavities, identifying the regions that should be eroded by EDM has become a time-consuming and error-prone work for toolmakers. A fuzzy approach to automatically select optimized processing method for manufacturing features is proposed in this paper. Some examples are also included for discussion. The results showed that this approach ...Show More
This paper describes a design system with unified expression of the design knowledge based on the ontological driven method according to the characteristics of electrical casting products and dies. A detailed discussion about the knowledge modeling technology including the knowledge representation model of products and dies is put forward. Further explanation of the modeling strategy of the whole ...Show More
The purpose of this paper is mainly focused on the stability problem in the numerical analysis of the convection dominated problems. Due to the advantages of dealing with boundary conditions and introducing upwinding concept, an improved local radial point interpolation method (ELRPIM) is presented to deal with the convection dominated problems. Based on the local radial point interpolation method...Show More
