Abstract
It is recognized that in the design software the available sheet metal features and DFMA (Design for Manufacturability and Assembly) guidelines include several different feature functions. The purpose of these functions is to ease the designing process beforehand by taking into account manufacturing points of views. There are however problems in the characteristic features -which can be functional, geometrical and/or non-geometrical - of current design software. Behind these features there can be differences in designers' opinions, different opinions based on calculation models or standards, or different pre-selection/default values based on the program's user interface. Depending on the designer's background the different design features can be prioritized in numerous ways. A similar 3D-model of a product can include several different parallel PDM data packets, resulting in the final product after the manufacturing not meeting specifications. With products that have been designed for the networking environment, PDM data needs suitable pre- and after-filtering to increase the reliability of manufacturing. The described problematic situation is created in bending and bunching, when manufacturing case structures, which include a separate lid. The ever-changing digital environment leads to a situation where the information integration from feature based design software's to PDM system is flawed.
