• It is first and the only series of books of V. A. Zharkov in the world on a computer designing of technological processes of the industry in Computer-Aided-Design/Computer-Aided-Engineering-systems (CAD/CAE-systems) on the example of a designing the technological processes of stamping in the CAD/CAE-system Marc of MSC Software Corporation (USA).In this volume 7, is developed the methodology of 3D-modeling the technological processes of processing the blanks and obtaining the details after a forming on example of widespread operation in the industry: the bending of sheets, strips and profiles from a steel, an easy aluminum alloy and a composition-bimetal taking into account the hardening and anisotropy. The modeling is based on designing of rated model only on the basis of own powerful graphic possibilities of system Marc without usage of any additional input files and without a writing of programs. For the purpose of understanding the mechanism of bending a blank, for the correct development of the project in CAD/CAE-system and the correct analysis of results of modeling the bending in this system, in the beginning of the main chapters is resulted the engineering theory of bending by V. A. Zharkov with analytical dependences. And only then more is given the exact numerical modeling in CAD/CAE-system. In the chapter 10, are resulted the calculation of parameters of bending and the examples of optimal and rational layout of blanks for bending on sheet on the basis of mathematical linear programming in projects of environment of development Microsoft Visual Studio with writing of programs on the main, in the programming world, language Visual C#.In chapter 11, began a theoretical research and CAD/CAE-modeling of process of a bending on four-roll machines of cylindrical details from sheets for airframes of rockets and pipe products. In the 1st edition of this volume, the schemes of all main stages of a bending of the cylinder are shown. But the engineering theory of Zharkov V. A. is still developed, also CAD/CAE-modeling is executed only for the 1st stage, namely, the subbending an edge of flat blank. Other stages of a bending of the cylinder on a roll machine will be investigated in the following editions of the given volume from the series of books of Zharkov V. A. on CAD/CAE-modeling.The book consists of the six sections: CAD/CAE-modeling in system Marc of the one-angular bending, two-angular bending without a holder and with a holder of blank, four-angular bending, stretch bending, CAE-modeling in Microsoft Visual Studio of optimal layout of blanks, forming the cylinder on roll machine, and the sections consist of 11 chapters. Following the circumstantial step-by-step instructions in the book, any user, even without special preparation, can quickly create the own project in CAD/CAE-system, and further the user can model, study, research and put into practice the processing of blank, to reduce the design time of processing and the cost price of manufacture of bent details in rocket- and aircraft construction, chemical and oil- and gas mechanical engineering, automobile, aircraft, electrotechnical, crockery, packing and other industries.The book is intended for engineers and scientists, working in various industries, and also for students and teachers of technical institutes and universities.
