in forging design the significant parameters are maximum load or energy which are required for the selection of forging press or hammer. these two parameters are varied by the other paramelers such as the geometry of die cavity, flash dimensions, shape of the work piece, friction, mechanical properties of the metal to be forged, temperature, strain rate, and number of the forging operation. the...

A new type of computer-aided engineering environment is envisioned which will improve the productivity of manufacturing/industrial engineers. This environment would be used by engineers to design and implement future manufacturing systems and subsystems. This paper describes work which is currently underway at the United States National Institute of Standards and Technology (NIST) on computer-a...

This research project combines computer-aided-engineering methods with practical control strategies to develop precise fabric handling capabilities. The primary goal is to develop mechatronic design concepts for assembly processes such as: folding, joining, placing, and locating that take into account variability in fabric material properties such as weight and stiffness. Three-dimensional mode...

Le langage de spdcification fomlelle est fond6 sur les structures de traits typ6s. La r6utilisation de spdcifications linguistiques est favoris6e par l'organisation de ces sp6cifications darts un style par objets, en plusieurs niveaux de sp6cificit6 croissante. Ce langage est suffisement puissant pour pouvoir d6crire tout type d'objet linguistique, et a l'avantage d'utiliser une notation largem...

The engineering design process evolves products by a collaborative synthesis of specifications, personnel and organizations. Unfortunately, collaborative effectiveness is thwarted by existing single-user computer-aided applications like computer-aided design, computer-aided analysis, and others. These applications and associated file management systems assign editing rights to one technical per...

Computer-aided process engineering and conceptual design in energy chemical has played a critical role for decades. Conventional computer-aided system generally starts with flowsheets that...

Computer-aided drafting and design (CADD) is a computer-based program that improves the efficiency of product design and components both inside and outside of engineering. In recent years the use of CADD in dentistry, more commonly known as computer-aided dentistry, has become commonplace, allowing doctors and patients to individually design treatment with the result visible through computer-ge...
