“…This issue leads to fewer chances for verification of the product and production system during the later phases of the product introduction process ( Javadi et al, 2013;Rahim and Baksh, 2003). Furthermore, Vallhagen et al (2013) indicate that the main focus during the product introduction process in low-volume manufacturing industries is on the of the product rather than on its manufacturability. Therefore, optimising the production processes is not typically considered, and the only thing that is assured is that the producibility of the product by means of existing processes.…”

AbstractPurpose -The purpose of this paper is to understand how the characteristics of low-volume manufacturing industries influence the product introduction process and factors which can facilitate that process in low-volume manufacturing industries. Design/methodology/approach -A literature review and a multiple-case study were used to achieve the purpose of the paper. The multiple-case study was based on two product development projects in a low-volume manufacturing company.

“…Thus, manufacturing variation in key product characteristics becomes a critical issue. Therefore, for this type of application, producibility criteria cannot solely rely on the time and cost spent during the manufacture and assembly but also on the quality built into the product, as suggested by the authors in previous studies [33,34]. The objective then becomes to reduce quality-related failures during production, thereby minimizing rework costs.…”

Designing aircraft engines is a complex process in which requirements from multiple disciplines need to be considered. Decisions about product geometry and tolerances to achieve optimized aerodynamics, product life and weight can affect the manufacturing process. Therefore, providing information to designers about process capabilities is necessary to support design exploration and analysis. In this paper, the authors propose the Welding Capability Assessment Method (WCAM) as a tool to support the systematic identification and assessment of design issues related to product geometry critical to the welding process. Within this method, a list of potential failure modes during welding is connected to specific design parameters. Once the critical design parameters have been identified, quantitative methods are proposed to calculate tolerances to reduce the likelihood of welding failures. The application of this method is demonstrated through an industrial case study where a combination of interviews and welding simulations is used to study the welding capability of a number of product geometries. This method represents an advancement from traditional qualitative guidelines and expert judgments about welding difficulties towards a more quantitative approach, supporting virtual design.

“…Manufacturability refers to how a product can be produced to a minimal cost and at a maximal reliability. However, there are several influencing factors, as described by (Vallhagen, Madrid et al 2013). Manufacturability can for instance refer to the complexity of the geometries, how well the different parts can me assembled, how difficult the materials are to form and so on (Bralla 1999, Boothroyd 2011).…”

Computer simulations play an important role for evaluating designs in an early stages leading to that more informed decisions can be taken and thereby reducing the risk of costly re-design. In this paper, a platform currently in operation at aeronautical company for doing extensive automated multiobjective design parameter studies on conceptual designs of aircraft engine components is studied. In the paper, an extension of the capability of the platform into making a rule-based evaluation of the welding manufacturability of the conceptual designs is proposed. The extension is tested by a prototype system at the air-craft manufacturer showing the relation between the design parameters and the manufacturability of the components. The results are presented as a manufacturability index showing what trade-offs with other performance criteria of the engine that can be made. It is shown that the manufacturability evaluation can be integrated in the knowledge value stream and supports a set-based concurrent engineering approach in the company.
