The design of extrusion dies depends on the experience of the designer. After the die has been manufactured, it is tested during an extrusion trial and machined several times until it works properly. The die is designed by a trial and error method which is an expensive process in terms of time and the amount of scrap. In order to decrease the time and the amount of scrap, research is going on t...

Purpose: The present paper describes a knowledge-based system (KBS) developed for selection of progressive die components to automate the design process of progressive dies in stamping industries. Design/methodology/approach: The production rule based KBS approach of Artificial Intelligence (AI) has been utilized for constructing the proposed system. The system has been structured into seven KB...

The Internet and World Wide Web (WWW) are evolving as an important communication technology. This paper aims to develop methodology for enabling better concurrent stamping part and die development, in the evolving Web technology. The characteristics of concurrent stamping part and die design are presented, and the necessity and feasibility of building Web-based concurrent stamping part and die ...

Design of deep drawing die is a skilled and experienced based activity. Selection of die components is a vital step in the design process of a deep drawing die. This paper describes a knowledge based system (KBS) developed for the selection of major components of a deep drawing die. The proposed system uses production rule based approach of artificial intelligence (AI) and consists of eight mod...

Nowadays Aluminum extrusion die design is a critical task for improving productivity which involves with quality, time and cost. Case-Based Reasoning (CBR) method has been successfully applied to support the die design process in order to design a new die by tackling previous problems together with their solutions to match with a new similar problem. Such solutions are selected and modified to ...

in recent years, in order to reducing die design and manufacturing costs, multi point forming technique has gained an increasing interest because of its high flexibility. in this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. in this paper, the fundamental principles of multi-point forming was described and the possib...

Digital Item Adaptation (DIA) ist der jüngste Standard im Rahmen des ISO/IEC MPEG-21 Multimedia Frameworks. Dieser Standard spezifiziert Deskriptoren und Konzepte (Tools) für die interoperable Kommunikation und ggf. Adaption von komplexen digitalen multimedialen Objekten, sog. Digital Items. Schwierigkeiten der Kommunikation und ggf. die Notwendigkeit der Adaption multimedialer Inhalte entstehe...

Kurzfassung: Die vorliegende Arbeit stellt ein Modell vor, mit dessen Hilfe synthetische Haushaltslastprofile generiert werden können. Diese Lastprofile werden mit hoher zeitlicher Auflösung (Sekunden) dreiphasig jeweils mit Wirkund Blindanteil erzeugt. Neben dem Aufbau und Leistungsumfang wird kurz auf die Parameterermittlung des Modells eingegangen. Es werden daran anschließend Beispiele für ...

There are many limitations and benefits of mobile technology and the specific situation of mobile users adds complexity through additional parameters that designers need to address. This makes designing user interfaces and user interaction for mobile applications a very complex task. To address this complexity we propose an interaction design approach using patterns for mobile interaction desig...
