network solutions, and utilization of
advantages of feature-based modeling. 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. 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. This
study will focus on five issues that are included either in DFMA or PDM,
or both: the 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, 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, it is suggested that the
responsibilities for developing DMFA and PDM applications with proper
design parameters could be analyzed more deeply
between persons working with information exchange, product design,
software design, or production machine design.
