歪脖Abstract. The world scientific and industrial community enters prently
a new pha of its development. Suffice to mention such key developments
as the strategy of development of “Industry 4.0” for German manufacturers
[1], two American concepts: “Industrial Internet” [2] and “Internet of
things” [3]. The work on artificial intellect [4] relead in 2003 laid the
bas for industrial development of systems with artificial intellect, while a
wide discussion on the Fourth industrial revolution [5] as a continuation of
the concept of “The cond industrial era” [6] was initiated in 2016 at the
World economical forum. The implementation of the industrial concepts英国利兹
brings about a high level of competition and, as a result, arching new
technologies of manufacturing competitive produce. The manufacture of

apprehension a great volume of information connected with the results of
designing, simulation, marketing and sales of the factories’ produce. The

program Industry 4.0 implies a wide u of the cutting-edge digital

technologies and, particularly, the technologies of virtual and augmented
reality.
The point at issue is the expansion of technologies of digital engineering in the direction of technologies of virtual engineering with an active application of multi-screen systems of virtual environment CAVE 3D (Computer Aided Virtual Environment) and technologies of augmented reality (Fig. 1).

There are two types of predictive simulation problems: ordinary and extraordinary. There is a guarantee of getting solution by means of commercial multi-purpo software code for ordinary problems, which is perfectly well provided by the t of models and numerical diagrams of this code. This type of simulation is characteristic for the stage of development of the industrial revolution Indus
try 3.0. The prent time demands solving call problems for creating the breakthrough technologies to provide development of the prent-day industry. This means that the solution of science extraordinary problems is on the agenda, which demands the new approaches at all stages of solution simulation.
However, the latest versions of commercial software code are in arrears of the advanced frontiers of science by 10+ years immediately after relea. In view of this fact it is impossible to provide solution of extraordinary problems by the t of physical and mathematical models of commercial multi-purpo code owing to inadequacy of the ud or due to ineffective scaling of calculations (Fig.2). In order to solve the extraordinary problems, it is necessary to develop the unique physical models and equations of the object state, development of numerical diagrams of solving equations and, as a result, building the problem-oriented in-hou dedicated software system with all attributes appropriate of the modern system, including pre- and post-processor, on-line help, means of forming online report and analyzing simulation results in in-situ mode on the basis of virtual environment systems.

The stage of development of engineering technologies in the program Industry 4.0 is characterized by conducting analysis of results of predictive simulation using the means of systems CAVE 3D [7], which are the decision-making centers in the context of analysis of results (Fig. 3).沙漠里的仙人掌

Recently, reasonable attention is paid to the problem of analyzing results of predictive simulation in НРСsystems in in-situ (on-the-fly) mode. Two circumstances contribute thereto. First of all, the emergence of hardware in the market, which helps obtain a high-quality image and, condly, an acute necessity of “on-the-fly” analyzing results with the aim of monitoring and correcting the progres
s of making calculations in НРСsystems. Particularly, it is applicable to the problems bad on multi-scale and interdisciplinary models (turbulent combustion process, etc.), which demand extensive resources of НРС
systems. Thus, a chance has appeared recently to adequately improve the process of analyzing results of predictive simulation in НРСsystems in “on-the-fly”mode with the u of virtual environment systems.
The technologies of virtual engineering feature significant advantages over digital engineering technologies, which dominated prior to beginning of the industrial revolution Industry 4.0 stage. The main advantage consists in a significant shortage of industrial waste since a comprehensive control of results of 3D model simulation in virtual environment system CAVE 3D takes place prior to beginning the article production (Fig. 4).

At the same time the growing level of high competition in the industry stimulates the development agencies and manufactures of the machine-building produce get across the advantages of a particular product to a buyer of the machine-building produce quickly and in an understandable fashion. Therefore, a growing interest is obrvable prently to the developments of virtual technica
l manuals on the basis of augmented-reality technologies.
A virtual technical manual has been created together by EMUGE-FRANKEN (Germany) and Peter the Great St. Petersburg Polytechnic University at the chair of “Computer technologies in machine-building”. EMUGE-FRANKEN, the German company boasting more than 90 years of experience, develops and manufactures the precision tools as well as high-accuracy высокоточнуюtooling equipment for fastening the parts to be machined during machining at the industrial enterpris. Creation of such tooling-related solutions in the technology of cutting and milling thread makes a basis of the business.
An animated model of screwed-shank chuck HF20 asmbly has been lected as an “augmented reality” (Fig.5). The company’s experience shows that this product is needed by the companies on the Russian market dealing with metals processing by drilling and threads generation.

The augmented reality makes it possible to better understand such advantages of the product as: possibility of shank replacement with the shank of the required shape (standard and size) and adapt the screwed-shank chuck to different variants of machine-tool spindle, possibility of changing adapter for a required task, e.g., drilling hole or cutting thread. The 3D interactive models and augmented-reality animations provide for a new level of training, understanding documents by the experts or urs.

An image of the screwed-shank chuck in the catalog is ud as “Target ”. In ca the image comes in view of the camera of tablet or Smartphone the animation of quence of asmbly of the screwed-shank chuck, adapter and tap will be output to the screen of a device (Fig. 7).
