Concerns about the environmental impacts of used and discarded products have recently led to enactment of laws that regulate the amounts of hazardous substances and recyclable content in products. The laws also make the Original Equipment Manufacturers (OEMs) responsible for recovery and proper treatment of these end-of-life products. In this two part paper, we present methodologies for OEMs to use the Product Lifecycle Management (PLM) framework to effectively meet the challenges posed by these regulations. In this second part, we outline a methodology that can enable case-by-case selection of the treatment strategy for incoming end-of-life products. To extract product information required for this selection, we develop rule-based heuristics for identification of joints directly from CAD assembly models, along with their type, size, location and orientation.

The purpose of this research is to make design automation possible by parametric design and design associability in 3D CAD. Applications of the technology in liquid food packaging machinery and its advantages are presented in the paper. For regular shapes such as circles or lines, parameters are used to link the dimensions of relative parts while for irregular shapes such as curves, associability is used to do the job in an assembly. Commercial 3D CAD software and Microsoft Excel software were used for the application. It is proved that same merit applies to designs of other machineries, on reducing design time and design mistake, enhancing consistency and easy documentation， therefore liberating designers from redundant day-to-day routine computer-paperwork to make more innovative contributions to their job. The impact of the design-automation technology on machine design is great.
