Effective production in networking environment of sheet metal products needs accurate and relevant PDM (Product Data Management) data, appropriate modelling of components supported by local and global network solutions and utilization of advantages of feature based modelling. To enable these aspects of effective production in sheet metal production it is necessary to evaluate the integration of DFMA (Design for Manufacturing and Assembly) and PDM data. This paper aims at identifying the challenges of DFMA and PDM integration through recognizing possible malfunctioning parts of their integration. The observations are based on sheet metal specimens in which the DFMA and PDM aspects are visible in punching and bending. Moreover, this study will focus on five issues, which are included either in DFMA or PDM data or both: effects of different calculation methods for the flattened length, utilization viewpoints of global or local manufacturability guidelines, assembly conditions, options to tune the manufacturing process instead of changing the product geometry and possible additional requirements given by the customers. Based on practical design and manufacturing tests of sheet metal products, it has become evident that one option to improve the quality of analyzed sheet metal parts is to further develop the integration of DFMA features with the workshop's cutting and punching parameters. As one possible improvement to these kinds of integration tasks of DFMA and PDM data it is suggested that the responsibilities for developing DMFA and PDM applications with proper design parameters could be analyzed deeper between persons working with information exchange, product design, software design or production machine design.
