This paper describes a prototype software system that implements a form of featurebased design for assembly. It is not an automated design system but instead a decision and design aid for designers interested in Concurrent Design. Feature-based design captures design intent (assembly topology, product function, manufacturing, or field use) while creating part and product geometry. Design for as...

To enable next generation CAD tools to effectively support top-down design of products, a top-down assembly design process is refined from the traditional product design process to better exhibit the recursive-execution and structure-evolvement characteristics of product design. Based on the top-down assembly design process, amulti-level assemblymodel is put forward to capture the abstract info...

translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...

In this paper, a flexible beam-based modeling method is proposed for dimensional control of the sheet metal assembly process. This method uses developed decomposition principles of key design and manufacturing characteristics for integration of assembly process and product design. It allows for modeling of assembly processes and product in the early design stage of process and product design. T...

This paper discusses the rationale of process platform-based production configuration in mass customization production. A multilevel system of nested colored object-oriented Petri nets (PNs) with changeable structures is developed to model the configuration of production processes. The obtained process for a new member of a product family involves both manufacturing and assembly processes for t...

tion solutions for the assembly of metal structures using the KUKA LBR iiwa lightweight robot. The shop-floor worker can instruct the assembly process on the shop floor by just showing the desired arrangement without the need for complex manual robot programming. The assembly process is automatically planned and converted into a robot program for execution. Dexterous skills based on the robot's...
