Digital production technologies are the processes of transition of digital design into a physical object.Digital production is based on the integration of mechatronic technologies, computer systems with computational modeling tools, 3D visualization, reverse engineering and engagement of different equipment and technical devices with software for the purpose of developing the designs of products, technological processes for their manufacturing and operative management of industrial processes.
This concept is illustrated in Fig. 1 depicting continuous digital processing.Digital production ensures efficient establishment of the sixth technological paradigm, increasing the automation rate, growth of labor productivity, production flexibility, and opportunity for accelerated launching of innovation products into manufacture and change in generations of machines and technology.

Strategic phase
Technological phase Development phase Launch phase There are 5 target criteria of production digitalization.

Production
• Economic efficiency Maximum synchronization of the entire range of design works, optimization and interdisciplinary approach to cooperation, as well as data updating and correctness allow decreasing the time and cost, hence, increasing the economic efficiency in general.
• Prototyping Creation of a 3D digital model or a digital twin allows increasing the efficiency and revealing the design issues early on.Assets that generate millions of data points and allow analyzing their value.
• Quality control The need for production planning is caused by the desire to work with maximum efficiency and minimum expenses while maintaining the required product quality level.Quality control begins with production planning and ends with end product delivery.Throughout all the stages, quality control criteria shall be reflected in the standards of the organization/enterprise with clearly defined requirements.
• Interaction Integrity, complexity and availability of design data, as well as its unhindered flow in the information space shall provide for integration of all the planning and production participants.
• Standardization Process standardization is the initial stage of organization excellence; it includes continuous updating of standards in order to increase their practical efficiency.
Implementation of the above target points requires introduction of new tools at the initial stage of shifting to digital production and leads to additional costs, but in the aftermath these expenses will be compensated.The dependency of resources and expenses saving is shown on the diagram (Figure 2).Innovation design of digital production usually implies the availability of the following computerized components: intellectual model(s) forming the digital mockup of the product(s) for information support of all manufacturing processes; information technology of production innovation preparation, which is the basis of the development and engineering of design and optimization of all the production processes at the enterprise; highly automated processes allowing launch of new products (innovation products) into manufacture by establishing autonomous production with intellectual models (using artificial intelligence means) and digital processes, including PMISs project management information systems for digital production; control systems such as DNC (Direct Numerical Control) are systems controlling a machine group from a single PC with shared memory for software distributed by requests from machines.Such NC units are top grade devices, which ensure arranging of coordinated operation of technological facilities included in the complex, e.g., in FMSs; 3D printers or additive machines (if additive technology is engaged) for printing items several meters long; mechatronic machines, industrial robots and other PC-operated technical devices complementing popular flexible manufacturing systems, robotic production and intelligent production systems.

Conclusion
Trends for enterprises of the fifth technological paradigm in top industrial countries point out the necessity of adjusting the list of critical technologies in the Russian Federation.Nowadays, this list is supplemented with digital technologies.
Establishment of digital production at mechanical engineering and instrument engineering factories based on development and introduction of new critical and high technologies and innovation projects provides for the following: growth of production volume and production capacity; decreased lead time and launching of innovation products and new generation devices into manufacture; increase in the domestic market competitiveness; increased production flexibility with changes in the product range, stock list and industrial program of innovation product manufacturing by creating a sector (cluster) of digital production enterprises.
The conducted test process works on design and implementation of digital production at the enterprises showed that the following allows validating both the implementation of digital technologies and digital production projects in general: 3D modeling of digital production in a VR room; simulation modeling of equipment loading for feasibility study of product consistency batch launch processes and plant development; and simulation modeling of innovation projects of digital production.
