21st CIRP Conference on Life Cycle Engineering Product Remanufacturability Assessment Based on Design Information
2014
Existing studies on CAD-based remanufacturability assessment are either based on design charts or consideration of simple embodiment design f eatures only. This paper presents a remanufacturability assessment model based on design information in CAD models, e.g ., bill of material, assembly and mating features, dimensional and tolerance features, etc. A set of design feature-based metrics is proposed for product re manufacturability assessment, namely, disassembly complexity, fastener accessibility, disassemblability, and recoverability. The metrics are in tegrated into a generic model to analyse the feasibility of a product for remanufacturing. A case study using an automotive part is presented to demonstrate the effectiveness of the model.
