“…Modern modelling approaches such as the use of genetic algorithms and case based reasoning (CBR) systems are increasingly being applied for forging of single material components with promising potential to be extended to multi-metal production. Optimisation studies [138] have proven that knowledge based systems, once having defined appropriate boundary constraints, can rapidly converge to an optimised solution in a relatively short period of time. However, the user should take care in the selection of boundary condition constraints as optimisation systems may converge to local rather than global solutions.…”

This paper provides a review of recent developments in the manufacturing of lightweight multi-metal components, and in particular gears. The literature has shown that significant efforts have been made in manufacturing light gears and numerous technical challenges exist when designing for and manufacturing with dissimilar metals including challenges in heating technologies, mechanical performance, processing parameters, metal compatibility and the interface layer between adjacent materials, as well as difficulties in multi-metal simulations. Whilst the scope of multi-metal manufacturing is vast, the main concentration of this study is on the main stages of multi-metal gear production, and specifically on preform production, multi-metal heating, intermetallic bonding, and modelling of essential forming parameters. The effects of each of these methods as well as the numerous approaches studied in the literature are presented, with a recommendation being made as to a processing route that may lead to a robust multi-metal gear with minimal production line modifications to conventional steel gears.

“…The CBR methodology helps designers find previous design situations similar to the new situation without having to convert the design knowledge into rules or models. This solution is usually preferred by designers, resulting in many applications of 5 of 18 CBR to product designs [15][16][17][18][19]. Nevertheless, there are also approaches integrating CBR into other techniques [20][21][22][23][24][25].…”

Improving product sustainability is becoming an increasingly significant challenge for modern enterprises. A growing number of manufacturers are interested in enhancing product sustainability throughout the product life cycle. This study is concerned with using case-based reasoning to identify ways of improving product sustainability and select variables for model specification. Parametric models are applied to search for opportunities to improve product sustainability. This can be achieved through changes introduced at the product design stage. Simulations are performed using constraint-satisfaction modeling to identify conditions for achieving the sustainability targets of new products. Constraint-satisfaction modeling provides a suitable framework for finding all possible sustainability-enhancing changes (if any) during the new product development process. These changes may support R&D specialists in identifying opportunities to improve the sustainability of new products. We demonstrate the usefulness of the proposed approach with an example in which our method enabled a reduction in the product failure rate and an increase of battery lifespan for a robot vacuum cleaner line. We analyzed several factors affecting two targets of product sustainability: minimizing the product failure rate and maximizing battery lifespan. Our findings indicate that R&D staff size is the biggest factor in reducing the product failure rate, and that battery capacity is the most significant factor in battery lifespan.

“…Daher wird im Rahmen des Teilprojektes "Gestaltung und Dimensionierung" erforscht, wie das erarbeitete Wissen gespeichert und abgerufen werden kann. Dafür befindet sich eine rechnerunterstützte Entwicklungsumgebung im Aufbau, die Werkzeuge zur Potentialfindung, Wissensspeicherung [3] sowie zur Auslegung [4] und Konstruktion von Tailored-Forming-Bauteilen bereitstellt [5]. In diesem Artikel wird ein Ansatz für eine rechnerunterstützte Konstruktionsmethode beschrieben, mit dem die entwickelten Tailored-Forming-Bauteile fertigungsgerecht auf die zur Verfügung stehende Fertigungsprozesskette angepasst werden können.…”

This article describes an approach for designing knowledge based Computer Aided Design (CAD) models to represent the complete solution space of the Tailored Forming process chain by depicting the production stages of a component. The aim is to use this knowledge base to determine during the product development process whether the desired component can be manufactured with the available equipment, even if the design engineer does not have the necessary expert knowledge. In addition to the model structure, the implementation of the manufacturing restrictions and the dependencies between the different production stages are shown. The procedure is described using the newly developed tailored forming process chain as an example.
