in this study, the formation of different parts of a cup during deep drawing process has been investigated analytically using the geometrical relationships. for a given punch travel, the effects of the bending angle, and those of the die and shoulder radii on the flange and die shoulder strains were examined. in addition, different components of the deformation force were calculated and the pun...

A transfer or progressive die process consists of multiple stations working simultaneously in each stroke. This paper aims to develop a new methodology that can decompose press tonnage signals to obtain individual station signals without using in-die sensors. In the paper, two different tonnage decomposition tests, as well as the associated data analysis algorithms, are developed. Statistical p...

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...

Plastics extrusion is a manufacturing process suitable for continuous profiles such as floor skirtings, window frames, and pipes. In industrial applications, extrusion is a large-scale process, financially attractive only for mass products. This is due to the time consuming and costly regulation of the extrusion process and especially, the design of an extrusion die which relies on running-in e...

The aim of this study was to evaluate the compaction property of several pharmaceutical materials by measuring the die wall pressure. The profile of die wall force during tabletting process was measured with the compaction process analyzer (TabAll). Several compaction parameters such as maximum die wall pressure (MDP), residual die wall pressure (RDP) and pressure transmission ratio (PTR) from ...

The extrusion processes of ceramic pastes, including 3D printing, are used for the production high-value products. Ceramic paste is a complex process which depends on rheological properties, die and extruder geometries, operational parameters. Modeling quantitative analysis molding important to design proper extrudates desired strength, shape, morphology. In this paper, mathematical model ram m...

Profile im Internet haben in der heutigen Zeit einen wichtigen Stellenwert eingenommen, um eine Identität online zu repräsentieren und erfreuen sich nicht zuletzt deswegen immer größerer Beliebtheit die allgemeine Beteiligung an sozialen Netzwerken hat in den letzten Jahren drastisch zugenommen. Dies führt unter anderem dazu, dass auch soziale Netzwerke und deren Profile zur Zielscheibe von Int...
