Up to one third of the population will die as a direct result of cancer. Accurate and timely diagnosis of disease often requires multiple different approaches including the use of modern imaging techniques. Prompt recognition of adverse consequences of some anti-cancer therapies also requires a knowledge of the optimum imaging strategy for the problem at hand. The purpose of this article is to ...

The purpose of introducing ultrasonic vibrations in the tube hydroforming process is to create more formability by obtaining a lower corner radius, improve thickness distribution of the wall and provide good tribological conditions at the tube and the die interface. Vibrations imposed on the die create alternating gaps which improve the formability in the tube hydroforming process in the presen...

Understanding sheet metal forming presses are important to reduce manufacturing costs. Thus, the best method of finding optimum values processing is by studying effect parameters on behavior formability, friction, and die radius. In this work, deep drawing process a low-carbon steel cup was studied significance two investigated which friction coefficient radius die. The finite element program, ...

The objective of this study is to present a new numerical strategy using soft computing techniques to determine the optimal die gap programming of extrusion blow molding processes. In this study, the design objective is to target a uniform part thickness after parison inflation by manipulating the parison die gap openings over time. To model the whole process, that is the parison extrusion, the...

The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

Castings of aluminum and plastics are of high importance in the industrial world. They are usually made using permanent metallic moulds for pressure die-castings and injection molding. Die-tools are usually produced from chromium maraging hot work tool steel and are heat treated to hardness between 29 and 48 HRC, 1-3 . Die life is a mayor factor of a die-casting process and it strongly affects ...

das thema „orient“ besch?ftigte schon lange vor der institutionalisierung der orientforschung und entstehung von orientalistikschulen die deutschsprachige kulturszene und wurde vor allem seit der zweiten h?lfte des 18. jahrhunderts mit einem ungeheuren illusorischen potenzial intensiver denn je in literarischen werken und ubersetzungen sowie in geistesgeschichtlichen debatten thematisiert. die ...

Sheet metal forming die technologies show great progress in the industry daily. dies design depends on many parameters such as product's geometry, dimensions to be designed, number of products, and part operation. The main purpose designs is with optimum obtain high-quality products.One reasons for these errors damage elements during This studyanalyzed final process sheet using a progressive tw...
