To find out knowledge about a design that has disappeared, become outdated, or been concealed, reverse engineering is required. Techniques have advanced from manual measurements to making use of 3D scanning technologies. In order to ascertain the benefits and drawbacks of techniques and technologies that use 3D scanning for reverse engineering, this study conducts a literature review. In the branch of the mechanical engineering design and manufacturing-based sectors, reverse engineering is essential. This method's importance to the process of product design is generally acknowledged. In a typical computerized manufacturing setting, the machine activity that turns the raw materials into the finished product is typically last, while the product design frequently comes first. When original drawings or documentation are unavailable, it is frequently necessary to reconstruct a CAD model of the current part using any digitalization techniques. This model is then analyzed and modified in order to create a better product design. Characterizing geometric models and associated surface representations, data segmenting and proper surface fitting fundaments a crucial task in reverse engineering are all crucial tasks in the reverse engineering process.

This paper investigates integrating model representation descriptions in the form of charts and specifications at the stage of automated systems infological modeling, developed in order to solve design tasks on the methodology for automating intellectual labor (MAIT). In the process of creating the automated system on the basis of MAIT there were developed the following model representations: initial, conceptual, infological and datalogical. The infological model representation is invariant to the software and hardware environment and implementation means. The description of infological model representation includes the following forms (specifications) and charts: for a static component – P1 and P2, the chart of infological structure; for a dynamic component – P3 and P4, the chart depicting a system of subject accesses; for a functional component – P5 and P6, the chart depicting a system of subject manipulations; P8 and the matrix chart showing the model as a whole, including static, functional and dynamic components coordination. The features of building diagrams and the formation of specifications when creating an infological structure are investigated, on the basis of which a method and technique for integrating descriptions of static components for model-projects of automated systems that perform computational tasks in the design of mechanical engineering objects are determined. The article provides the integration of descriptions in the form of diagrams and specifications for the static components of infological model views. [ABSTRACT FROM AUTHOR]

The article deals with the special features of informatization and automation of production processes at the present stage of industrial development, associated with the active implementation of Industry 4.0 concept in the economic activities of manufacturing companies. The advantages of the technology of end-to-end design, preparation of production and production of serial mechanical engineering products, as an element of the "Industry 4.0" concept, in comparison with the technology of classical sequential, top-down design, are analyzed. The composition and block diagram of the hierarchy of the information model of a serial machine-building product for end-to-end design, preparation of production and manufacturing, adapted for all stages of the life cycle of such a product, are considered. Based on the analysis and study of the results of real projects for the implementation of systems and technologies of end-to-end design at transport engineering enterprises in the Sverdlovsk region, conclusions are drawn about specific competitive advantages obtained by enterprises when implementing the principle of end-to-end design, including quantitative assessment.

The CYCLE consortium has been designing the ITER ICRF antenna since March 2010, supported by an F4E grant. Following a brief introduction to the consortium, this paper: describes the present status and layout of the design; highlights the key mechanical engineering features; shows the expected impact of cooling and radiation issues on the design and outlines the need for future R&D to support the design process. A key design requirement is the need for the mechanical design and analysis to be consistent with all requirements following from the RF physics and antenna layout optimisation. As such, this paper complements that of Durodie et al [1]. [ABSTRACT FROM AUTHOR]

The Spallation Neutron Source accelerator will provide a 1 GeV, 1.44 MW proton beam to a liquid mercury target for neutron production. The expected highest doses to components are in the collimation regions. This paper presents the mechanical engineering design of a typical collimator highlighting the features incorporated to assist with collimator removal once it is activated. These features include modular shielding, integrated crane mounting, remote water fittings and vacuum clamps. Also presented is the design work in progress at present to validate the remote vacuum clamp design. This includes a test rig that mimics an active handling scenario where vacuum bellows can be compressed and clamps removed/replaced from a safe distance. © 2003 American Institute of Physics [ABSTRACT FROM AUTHOR]
