Uncertainty in Product Modelling within the Development Process

This paper gives an overview about how to locate uncertainty in product modelling within the development process. Therefore, the process of product modelling is systematized with the help of characteristics of product models and typical working steps to develop a product model. Based on that, it is possible to distinguish between product modelling uncertainty, mathematic modelling uncertainty, parameter uncertainty, simulation uncertainty and product model uncertainty.

Product Form Modular Design Based on Genetic Algorithm

After the European and American countries put forward the modular design in the 1950s, and it become a hot topic again in 2013. Modular design make a well experience for product form design, but it also has its limitation. because of Genetic Algorithm (GA) has the superiority of optimizing and solving, This paper proposes a modular, hierarchical product modelling design based on GA, Using iterative repeated optimization genetic operators to make product modeling design to achieve an optimal form.

Based on the Cimatron Plastic Shell Mold Design and Processing

The graduation design using CimatronE10 software shell model design, product modelling die, mold cavity, side pumping finish making mould numerical control programming and machining center operation. In mold cavity of the numerical control programming is described, the main analysis and technology essentials of each working procedure, flexible use of the secondary open coarse, increasing the auxiliary surface and other programming skills.
