Abstract: In this paper, the forming process of a central hub by radial-forward extrusion is analyzed by using the finite element software, ABAQUS. Radial-forward extrusion is used to produce hollow parts that generally feature a central hub with radial protrusions. Effective design factors such as mandrel diameter, die corner radius, die fillet radius, mandrel corner radius, tube wall thick...

LSIs that adopt advanced technologies, as represented by imaging LSIs, now contain 30 million or more logic gates and the scale is beginning to approach the level of 100 million gates. As compared with the 90 nm process generation, this is three to ten times the number of gates. With advanced technologies such as 40 nm and 28 nm, the process characteristics become remarkably complex and wiring ...

Metal stamping die design is a complex, experiencebased and time-consuming task. Various artificial intelligence (AI) techniques are being used by worldwide researchers for stamping die design to reduce complexity, dependence on human expertise and time taken in design process as well as to improve design efficiency. In this paper a comprehensive review of applications of AI techniques in manuf...

Die Bezeichnung " IT-Industrialisierung " ist eines der Schlagworte der heutigen Wirtschaftsinformatik. Damit wird die Übertragung industrieller Metho-den und Prozesse auf die Informationstechnik (IT) bezeichnet. Bei der " klassi-schen " Industrialisierung wurde die Frage der Gestaltung von (physischen) Pro-dukten immer bedeutender. Deshalb stellt sich die Frage, ob und in welchem Maße das Desi...

The use of function has been recognized as an important part of the design process over last two decades, especially at the conceptual design stage, due to its critical role in determining the final product’s functionality. Although there are now some general methodologies dealing with functions or reasoning about functions, virtually no commercial CAD system can support conceptual design proce...

On the basis, of the condition for demouldability, two levels of visibility, complete and partial visibility, are defined. The viewing directions from which a surface is completely visible can be represented as a convex region on the unit sphere called the visibility map of the surface. Algorithms are given for dividing a given object into pockets, for which visibility and demouldability can be...

Diecasting is one of the forming methods which is used for producing large number of components with good surface finish by injecting cast alloys in a metal mould under high pressure. Design of a diecasting die requires human expertise and is normally performed by trial and error method, which leads to monetary and time loss. Automation at initial die design stage will result in higher producti...

Universelles Design oder Design for All bedeutet, dass allen Nutzern die gleiche Benutzungsoberfläche angeboten wird, wobei Menschen mit Behinderungen ausdrücklich einbezogen sind. Ziel ist die größtmögliche Usability für alle Nutzer. Doch wie ist der Weg dorthin? Für uns als Usability-Professionals stellt sich die Aufgabe, Usability mit den Anforderungen der Accessibility zu verbinden: Im Tuto...

Durch Simulation oder formale Verifikation wird ein Design automatisch gegen spezifizierte Eigenschaften überprüft. Schlägt die Prüfung fehl, ist manuelles Debugging notwendig, um den oder die Fehler im Design oder der Spezifikation zu finden. Erste automatische Verfahren zur Eingrenzung der Fehlerkandidaten wurden entwickelt und bereits erfolgreich eingesetzt. Die Anzahl der Fehlerkandidaten i...

Prediction of the deformation characteristics is an important step to understand the workability of alloys during imposing large strains. In this research, severe plastic deformation of Sn-5Sb solder alloy was carried out under different t deformation conditions, including the temperature range of 298, 330, 36, 400 K and die designs. The current study applies an experimentally validated finite ...
