Feature Modelling for Assembly

A product modelling approach is presented that supports the assembly planning task with feature models. Mating and connection relations between components of an assembly can be specified by adding connection features to a product model with a design-by-features approach. In a second feature model, handling features can be specified. From the feature models, a decomposition of the assembly into subassemblies, and all possible assembly sequences can be derived. The features can also support grasp planning and motion planning. The design-by-features approach is embedded in an interactive design system that supports multiple feature views
