The development and design of engineering systems following amethodical approach based on information from the literature[9.1,2,3,4,5,6] is auseful procedure. The guidelines for design methodology have also been applied to interdisciplinary development projects
of this type, using aids such as requirements lists, the functional structure, and morph...

This paper puts forward a multiplatform identification method to overcome the limitations of a single platform strategy when mass customization is required. The method is applied to redesign or consolidate an existing product family. The method consists of four steps: (1) the determination of component values, (2) the estimation of component redesi...

... Following the engineering literature, one distinguishes: Product Design Model: a representation of a product. Design models can be specified at different abstraction levels and can be about different aspects of the device being designed, e.g. about geometry, dimensions, function(s), aesthetic qualities etc. [12,17]. ...

Product Lifecycle Management (PLM) deals with informa-
tion modelling across the entire lifespan of industrial products. The use of
computer-based technologies for PLM purposes requires product knowl-
edge to be specified in formal languages, so that the semantics of the
modelling elements is explicitly defined in relation to experts' conceptu-
alisations. Ontologies used in PLM contexts are often developed to satisfy
specific application requirements, and the meaning of the employed con-
cepts is left unspecified. In this paper, we present a preliminary ontology
focused on the notion of product from the engineering design and manu-
facturing perspectives. Our aim is to contribute at the development of a
comprehensive ontological specification of product knowledge for product
lifecycle modelling applications.
... From the literature review in the domain of environmental impact of production process it is possible to notice that nowadays the reported studies in the domain of metal forming processing predominantly focus on conventional material removing processes such as turning, milling and grinding; dealing with the influence of material removal and cutting fluids, in parallel with the electricity consumption. Gutowski (Gutowski et al., 2006;Gutowski, 2009) presented an environmental analysis of machining processes carried out at system level. In particular, a qualitative investigation was made concerning the impact of the material removal process itself as well as the impacts related to material production, cutting fluid preparation, tool and machine tool construction. ...
Production processes, as used for discrete part manufacturing, are responsible for a substantial part of the environmental impact of products, but are still poorly documented in terms of environmental impact. The present paper proposes a comprehensive energetic analysis of Single Point Incremental Forming Processes (SPIF). The three most commonly used machine tool architectures able to perform SPIF operations have been taken into account: a CNC milling machine, a six-axes robot as well as the dedicated AMINO machine tool were analyzed from an electrical energy consumption point of view. For all the setups, a working cycle time study and power study were performed. Moreover the contribution of each sub-unit towards the total energy demand has been determined. The influence of the most relevant process parameters (e.g. feed rate, step down), has been determined. The three setups have been analyzed in order to identify the solutions with the highest energy efficiency for SPIF processes and a set of potential environmental friendly process control strategies are proposed. Finally, a parametric model, able to predict the energy consumption at the varying of the process parameters, is proposed.
... Also topics related to energy consumption are rapidly becoming critical: actually, energy consumption impacts can be ameliorated to some extent by the ongoing pursuit of efficiencies within existing processes, but demand is anticipated to double in the next 40 years (Allwood et al., 2011). Such increase imposes to lessen the total impacts of material production and processing (Gutowski, 2009;Gutowski et al., 2006). ...

Gutowsky, (Gutowski et al., 2006;Gutowski, 2009) proposes a model able to calculate the electricity requirements for a manufacturing process as a function of the process and of the rate of the material processing.

Sustainability and sustainable production is nowadays a wide research field due the urgency of reducing environmental burdens of industrial production. Sustainable manufacturing issues are widely investigated too. In particular, due to the relevance such issues assume for automotive and aeronautical industry, the investigation of sheet metal forming processes sustainability is worth studying and, within this research fields, a certain lack of knowledge is still present. Many studies have been presented concerning the evaluation and reduction of environmental burdens in manufacturing. In this paper, the authors focus on sheet metal forming and aim to investigate both the efficient use of materials and process energy saving. The paper presents a sensitivity analysis which is based on experimental and numerical data. A traditional forming process (stamping) is numerically analyzed to determine process energy and also the amount of material utilized for the initial blank. An experimental campaign was instead developed on an incremental forming operation and energy measurements were obtained. Both the processes were carried out using two different aluminum alloys and two different sheet thickness values. Furthermore, two final component geometries were investigated for both of the processes. The analysis reached the conclusion that the investigated processes are quite different to each other as their environmental impact is concerned since both the required process energy and the possible material savings are rather different for the two operations. The obtained results allowed to formulate some comparison guidelines as sustainability of the investigated operations is concerned.

Sustainability issues are crucial topics in manufacturing and the reduction of environmental burdens for processes is highly requested. In particular, the evaluation of environmental sustainability for sheet metal forming processes is an widely investigated topic since there is still a lack of knowledge mainly due to the need of a proper modelling of Issues and factors to be taken Into account. The main task is related to a more efficient use of materials and also to energy savings. Moreover, forming technologies environmental impacts are essentially process-dependent. In this paper, a sensitivity analysis Is presented In order to compare, from a sustainability point of view, a classical stamping process with an incremental forming one both developed on aluminium alloys. Different process parameters and different materials are considered In order to evaluate the influence of such parameters on process energy and material wasting. The incremental forming tests were experimentally carried out while the stamping processes were numerically analyzed. The paper aims to enhance the awareness about the drawbacks and advantages offered by different technologies within sheet metal forming processes sustainability.
The development and use of educational robotics offer almost unlimited chances for teaching design. In classrooms it results in numerous and continuously increasing possibilities for the promotion of competences and the differentiated and differentiating use of educational robots. Therefore, this paper reports long time experiences of the author and is intended to introduce into the history and the relevant literature of educational robotics in teaching settings, before it discusses the role of educational robots as technology artefacts, as educational technology and for technology education interconnected to coding and the engineering design process (edp). In addition, a structured overview is developed to provide orientation, discuss possible applications and offer basic assistance for teaching between coding and engineering.
