Rapid Prototyping pp Cite as. In mechanical engineering, the development of a product from conceptual design to final production encompasses initial product description, mock ups for evaluation of alternative designs, product modeling, prototyping and tooling. This is an iterative process involving many refinements.

For visualization, data exchange or manufacturing applications, the geometric model has to be discretized into a 3D mesh composed of a finite number of vertices and edges. However, the initial model may sometimes be lost or unavailable.

Reverse engineering also known as backwards engineering or back engineering is a process or method through the application of which one attempts to understand through deductive reasoning how a device, process, system, or piece of software accomplishes a task with very little if any insight into exactly how it does so. Reverse engineering is applicable in the fields of computer engineering , mechanical engineering , electronic engineering , software engineering , chemical engineering , [1] and systems biology. There are many reasons for performing reverse engineering in various fields. Reverse engineering has its origins in the analysis of hardware for commercial or military advantage. It is only an analysis to deduce design features from products with little or no additional knowledge about the procedures involved in their original production. In some cases, the goal of the reverse engineering process can simply be a redocumentation of legacy systems.

RE is the generic name of a series of technical methods that convert physical parts into engineering concepts and CAD model. It has been an important branch of modern design methodology. With the development of computer and graphic design, RE has already no longer met the simple imitation products, but product innovation based on physical parts. In order to redesign the CAD model constructed by RE method and then support product innovation, hybrid CAD modeling method and some related key techniques are studied in this paper. Combining conventional design and RE, Hybrid CAD modeling method extracts features, constraints, and design intent from measured data for parametric redesign and eventually completes CAD model.

Reverse engineering

It enables the reconstruction of an object by capturing the component's physical dimensions and geometrical features. Manufacture of service components after discontinuation of the product line. Redesign of an existing design which lacks adequate product data documentation Corrupt data file or loss of CAD design for a product Generation of cheaper alternate products as a substitute for monopoly products. In order to accurately recreate the existing part, a computerized CAD model of the part's geometry must be developed in some manner. This CAD file provides the coordinates of multiple points on the product surface,used to develop the drawing of the product for redesign or manufacturing. This data may then be analyzed and improved within the CAD program.

The use of a CAD model is essential in many activities, such as manufacturing, design and mechanics. Reverse engineering is the procedure for reconstructing the CAD model of an object or component from measurements gathered by surveys of the object itself. Naturally, the measurements on the components can be performed using different techniques and instruments, but, currently, the best and most effective technique for geometrical surveys of objects is 3D scanning by means of 3D optical non-contact scanners. This paper describes the various reverse engineering techniques and how this procedure, associated with 3D scanning, can be advantageously applied to the concrete industry for digital production and for empowering and optimizing production plants. In industrial activities related to mechanics, manufacturing and design, projects of parts or assemblies are prepared and processed through CAD models, for the production or simulation of mechanical or structural behavior.

Reverse engineering of geometric models—an introduction

Сплошная мистификация. Блестящий замысел. Выходит, Стратмор был зрителем теннисного матча, следящим за мячом лишь на одной половине корта. Поскольку мяч возвращался, он решил, что с другой стороны находится второй игрок.

Стратмор кивнул. Ему не нужно было напоминать, что произойдет, если три миллиона процессоров перегреются и воспламенятся. Коммандеру нужно было подняться к себе в кабинет и отключить ТРАНСТЕКСТ, пока никто за пределами шифровалки не заметил этой угрожающей ситуации и не отправил людей им на помощь. Стратмор бросил взгляд на лежавшего в беспамятстве Хейла, положил беретту на столик рядом со Сьюзан и крикнул, перекрывая вой сирены: - Я сейчас вернусь! - Исчезая через разбитое стекло стены Третьего узла, он громко повторил: - Найди ключ. Поиски ключа не дали никаких результатов.

Наверху Сьюзан ждала возвращения коммандера, сидя на диване в Третьем узле словно парализованная. Она не могла понять, что задержало его так надолго. У ее ног лежало тело Хейла. Прошло еще несколько минут.

 Мистер Беккер, подождите минутку. - В чем дело? - Беккер не рассчитывал, что все это займет так много времени, и теперь опаздывал на свой обычный субботний теннисный матч.

Но именно правду она не имела ни малейшего намерения ему открывать. Она не доверяла Грегу Хейлу. Он был из другого теста - не их фирменной закваски. Она с самого начала возражала против его кандидатуры, но АНБ посчитало, что другого выхода .
