In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....

Dieses Paper gibt einen Einblick in Algorithmen der künstlichen Intelligenz – im Speziellen Algorithmen, die ihren Einsatz in Computerspielen finden. In einer Einleitung werden die Grundzüge künstlicher Intelligenz vermittelt. Es folgt eine Motivation, die zeigt, wozu man sie in Computerspielen benutzen kann und warum “Intelligenz” in Spielen notwendig ist. Nach einem kurzen Blick in die Entwic...

Klasse von probabilistischen Optimierungsverfahren, die “Ideen” der natürlichen Evolution nutzen. Wegen ihrer Universalität und Robustheit eignen sie sich besonders für komplexe Optimierungsprobleme bei denen klassische Optimierungsverfahren versagen. Der Artikel stellt die Arbeitsweise der Evolutionären Algorithmen am Beispiel des LKW-Einparkens vor, diskutiert die Vorund Nachteile des Verfahr...

Deformation behaviour during loading and unloading is studied in compression of an aluminium plate with a high ratio between the diameter thickness by DLC coated die. A compressed becomes thinner after to larger reduction loading. The plastic deformation confirmed measuring increase unloading. optimum profile die crown approaches reverse shape elastic deflection flat at stroke end increasing th...

Poly (3,4-ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT:PSS) was coated on flexible polyethylene terephthalate (PET) substrate using slot die on a roll-to-roll (R2R) system under different web tensions. The electrical resistance, the standard deviation of the recorded resistance and surface roughness of the coating under different tensions were analyzed. Based on these data an optimum ...

The present research work is concerned with the effects of optimum process variables in elevated temperature hydro-mechanical deep drawing of 5052 aluminum alloy. Punch-workpiece and die-workpiece friction coefficients together with the initial gap between the blank holder and matrix were considered as the process variables which, in optimization terminology, are called design parameters. Since...

Formation of spikes prevents achievement of the better material removal rate (MRR) and surface finish while using plain NaNO3 aqueous electrolyte in electrochemical machining (ECM) of die tool steel. Hence this research work attempts to minimize the formation of spikes in the selected workpiece of high carbon high chromium die tool steel using copper nanoparticles suspended in NaNO3 aqueous ele...
