The tooling and fixture play important roles in manufacturing and production. It affects both product quality and quantity. Better tooling and fixture can also promote cost-effective manufacturing process. This paper introduces a new type of universal clamping mechanism based on computer-aided 3D modeling, engineering structural analysis, and prototype testing. It can be applied to easily and reliably clamp different geometrical shape of work pieces per user requirements. This new clamping mechanism, with less moving components, can assist manufacturing industry for high speed production, easy part handling, precise clamping, and lower tooling cost.

Modeling with freeform features has become the standard in computer-aided design. Features offer a high-level approach to modeling shapes. However, in most commercial modeling packages, only a static set of freeform features is available. A new method for user-driven feature definition is presented, as well as a method to instantiate these user-defined features on a target surface. We propose the concept of a dual environment, in which the definition of a feature is maintained parallel to its instance on a target surface. This dual environment enables dynamic feature modeling, in which the user is able to change the definition of instantiated features on-the-fly.

3D design technology is the basis for the modern computer graphics. AutoCAD 2015 is a powerful version of computer-aided design system. We can solve complex tasks, without which this instrument can’t be solved in general. Using 3D design technology we not only save time working with a drawing. The geometric models are the foundation of the design basics, for working with drawing we can create projections, footnotes, sections and other modern graphics elements. AutoCAD can use and process the data from the model. This progressive design technology includes all parts of the design, starting from machine details, furniture and finishing with architectural forms of complex object models.

Kinetostatic  study  of  a  statically  determined  hinged  spatial  mechanism  without  redundant (passive) connection with an additional movable link – a rocker arm of a machine for processing parts, in which the working container performs complex spatial movement.  Methodology.  The  essence  of  the  kinetostatic  research  was  to  determine  the  radial  and  axial components of the reactions in all rotational kinematic pairs of the hinged statically defined spatial mechanism of  the  machine  for  processing  parts,  when  it  is  idling.  The  kinetostatic  study  was  implemented  using  the SolidWorks 2016 computer-aided design system with preliminary 3D modeling of this machine design with an additional moving link – a rocker.  Results. In the course of the kinetostatic study, 3D modeling of a machine with an additional movable link – a rocker arm in the SolidWorks 2016 computer-aided design system was carried out, the maximum values of the radial and axial components of reactions in all rotational kinematic pairs of the machine for processing parts were determined, the effect of changing the center distance of the intermediate connecting rod (working capacity ) on the increase in the maximum values of the reactions in all rotational kinematic pairs.  Scientific novelty. The relationship between the center distance of the intermediate connecting rod (working capacity) and the change in the maximum values of the reactions in all rotational kinematic pairs of the machine for processing parts is determined. As a result, it becomes possible to determine the maximum permissible center distance of the intermediate connecting rod to ensure the durable operation of the machine.  Practical significance. It is determined that the nature of the change in the maximum values of the radial  and  axial  components  of the  reactions  in  each  rotational  kinematic  pair  of  the  spatial  mechanism depends  on  the  value  of  the  coefficient  characterizing  the  ratio  of  the  center-to-center  length  of  the intermediate  connecting  rod  (working  capacity)  to  the  center-to-center  length  of  the  driving  or  driven connecting rods of the machine. The range of variation of this coefficient has been determined, within which it is rational to design this machine design. The results obtained can be used in the corresponding design bureaus of machine-building enterprises at the stage of designing tumbling equipment with a complex spatial movement of working containers.

Objective. The objective of the study is to consider the application field of modern device development and design methods using the means of 3D modeling and simulation of physical processes. The validity of the application and criteria for the reliability of the results obtained in the sequential design of the mechanical part of the electric drive and the control system are investigated.Methods. Methods of model representation of 3D objects in computer-aided design systems are considered, as well as methods for solving problems of determining strain under the applied load. Using the example of an elementary joint, the obtained results of the dynamic characteristic of an elastic shaft in a computer-aided design system are compared with those calculated analytically.Results. The article defines the basic principles and relations applicable to describing the shape of 3D models. Methods are shown by which it is possible to obtain information about the mass-centering model characteristics. The relations that form the basis of numerical methods for solving problems of determining elastic deformations of bodies are also given. The error that can occur when using insufficiently small elementary volumes in solving the problem of determining elastic deformation is shown.Conclusion. The use of 3D modeling in the design of complex technical systems is justified and speeds up production processes. However, numerical methods cannot always give an accurate result leading to the need to either increase the complexity of calculations or additionally adjust some designed device parameters.

It is obvious that the fundamental knowledge of the general technical discipline “Engineering graphics” should be in combination with a practical course of computer graphics, which allows students to integrate into the aviation products development system at the contemporary level. The article highlighted the need of design teaching at the initial stage of engineering and computer graphics study process. A drawing methodology includes 3D-modeling in a computer aided design program named COMPAS-3D. It is described a specific example of the mechanical part (aviation detail's elements – holders) with complex shape modeling algorithm in the application to the manufacturing technology of real products (casting, stamping, mechanical processing). Drawings development is based on 3D-modeling in COMPAS-3D. Proposed methodology was tested during engineering and computer graphics lessons in Moscow Aviation Institute (National Research University).

AbstractIn this study, we applied machine learning to mine the event logs generated in modeling process for behavior sequence clustering. The motivation for the study is to develop cognitively intelligent 3D tools through process mining which has been a hot area in recent years. In this study, we develop a novel classification method Command2Vec to perceive, learn and classify different design behavior during 3D-modeling aided design process. The method is applied in a case study of 112 participate students on a ‘Spiral-stair’ modeling task. By extracting the event logs generated in each participate student’s modeling process into a new data structures: ‘command graph’, we classified participants’ behavior sequences from final 99 valid event logs into certain groups using our novel Command2Vec. To verify the effectiveness of our classification, we invited five experts with extensive modeling experience to grade the classification results. The final grading shows that our algorithm performs well in certain grouping of classification with significant features.
