Material flow control for bending sheet metal workpiece

Abstract: The method uses a friction force sensor (25) detecting the friction force between the workpiece (2) and the lower holder (4) and/or the ring (3), for providing a regulation parameter for a regulation circuit (21) for the device. The regulation circuit uses the received friction force parameter for control of the workpiece holding force (FN) provided by a servo-controlled hydraulic and/or pneumatic cylinder (11).

Vorrichtung zur Bereitstellung von Befestigungselementen für ein Fertigungswerkzeug und Fertigungswerkzeug

Abstract: Die Erfindung betrifft ein Fertigungswerkzeug und eine Vorrichtung zur Bereitstellung von Befestigungselementen fur ein Fertigungswerkzeug (1), welches zum Verarbeiten eines Befestigungselements an einem Bearbeitungsabschnitt eines Werkstoffes ausgebildet ist, wobei die Vorrichtung eines aus einem Hauptspeicher ladbare Weicheneinheit (7) zum Bereitstellen von Befestigungselementen aufweist, wobei ein Befestigungselement uber eine Zufuhrleitung (11) einem Werkzeugkopf (2) des Fertigungswerkzeugs (1) fur eine Verarbeitung zufuhrbar ist. Erfindungsgemas umfasst die Weicheneinheit (7) mehrere Weichenmodule (8, 9, 10), von denen jedes Weichenmodul (8, 9, 10) einen Leitungsabschnitt der Zufuhrleitung (11) fur die Befestigungselemente bereitstellt, wobei die Leitungsabschnitte in Reihe geschaltet sind.

Control and Diagnosis in Integrated Product Development - Observations during the Development of an AGV

Abstract: This paper is concerned with the integration of control and diagnosis functionalities into the development of complete systems which include mechanical, electrical and electronic subsystems. For the development of such systems the strategies, methods and tools of integrated product development have attracted significant attention during the last decades. Today, it is generally observed that product development processes of complex systems can only be successful if the activities in the different domains are well connected and synchronised and if an ongoing communication is present - an ongoing communication spanning the technical domains and also including functions such as production planning, marketing/distribution, quality assurance, service and project planning. Obviously, numerous approaches to tackle this challenge are present in scientific literature and in industrial practice, as well. Today, the functionality and safety of most products is to a large degree dependent on control and diagnosis functionalities. Still, there is comparatively little research concentrating on the integration of the development of these functionalities into the overall product development processes. The main source of insight of the presented research is the product development process of an Automated Guided Vehicle (AGV) which is intended to be used on rough terrain. The paper starts with a background describing Integrated Product Development. The second section deals with the product development of the sample product. The third part summarizes some insights and formulates first hypotheses concerning control and diagnosis in Integrated Product Development.
