Model-Based Definition as a Method for Efficient Digital Product Definition : A Study of Feasibility and Implementation Requirements

Abstract: Mechanical engineers have difficulties when attempting to convey three-dimensional product information in a two-dimensional style. Effective collaboration between various users requires capability to deliver standardized data in a digital format. By digitizing product information and making it available for users apart from designers, Model-Based Definition (MBD) provides a solution by defining to product digitally in a three-dimensional environment. The use of MBD in mechanical design processes can have a positive impact on cost, time, and quality of the final product. Although there are standards for defining digital products, they sometimes do not satisfy specific needs of a variety of product landscapes, necessitating company-specific rules. For a successful deployment of MBD the IT infrastructure must be mature, and a company-tailored guideline document is required to bridge current gaps from standards to corporate needs. Therefore, the aim of this study is to analyse software tools and verify if the IT infrastructure is ready to support transition from drawing-based engineering to model-centric practice. Changes are identified and recommendations will be given. The gained experience from creating models in CAD software along with requirements and feedback from stakeholders and users of the product and manufacturing information is input for creation of the guideline and manual for MBD data practices. This supports the company’s transition to a more efficient product definition. With release of the guideline for applying MBD, the milestone is set to sustainably rely on models instead of drawings for communicating product and manufacturing information. The applied CAD programmes provide all functions transcribing MBD according to applicable standards. The resulting data sets can be interpreted by humans and machines, bringing significant benefits when advancing to model-based enterprise where models are used in all business operations.
