“…The development of intelligent and adaptive systems has found application in the development of modern mechatronic technological systems, including ones in robotics and for creating high-tech products correcting the cutting mode parameters in CNC systems [10,11]. An analysis of the grinding operations shows the importance of the temperature factor in ensuring the quality of the surface integrity of the gears being ground [11].…”

“…From the experimental data obtained, it follows that an increase in the grinding power leads to a corresponding increase in the temperature in the grinding zone. It is known that an increase in temperature leads to an increase in the depth of the grinding burn [10]. This will be reflected in the equations below based on corresponding scientific researches.…”

In accordance with the principles of hierarchical management, a comprehensive two-level management system is presented for the development and manufacturing of products for the stages of pre-production (the upper level of the management hierarchy) and for the actual production stage (the lower level of the management hierarchy). At the stage of pre-production, the gear grinding operation design on the “MAAG” type machines was carried out. For this purpose, a technique for optimizing the gear grinding parameters for a two dish-wheel rolling scheme has been developed, a mathematical optimization model containing an objective function with restrictions imposed on it has been created. The objective function is the gear grinding machine time, which depends on the operation parameters (gear grinding stock allowance, cutting modes, grinding wheel specification, part material) and the design features of the gears being ground (module, diameter, number of teeth, radius of curvature of the involutes). The article shows that at the stage of pre-production, the gear grinding optimization is a method of operation design. At the stage of actual production, a closed-loop automatic control system with feedback on the deviation of the adjustable value (gear grinding power) automatically supports the numerical power values that were found at the operation design stage, taking into account ensuring defect-free high-performance gear grinding (minimum number of working strokes and maximum longitudinal feeds). At this stage, i.e. when a robust longitudinal feed automatic control system is operating, the optimization carried out at the previous stage (pre-production) sets the functioning algorithm for the adaptive system with corresponding control algorithm. Thus, at the production stage (when the gear grinding machine is running), the operation optimization is a control method. Therefore, it is shown that with two-level control, the gear grinding operation optimization performs a dual function. On the one hand, it is a design method (at the pre-production stage), and on the other – a management method (at the actual production stage). With this approach, i.e. with the integration of production and its preparation based on a single two-level management, the efficiency of a single integrated design and production automation system is significantly higher due to general (unified) optimization, rather than partial one.

Defect-free machining of materials and products with a strictly organized anisotropic structure (polymer composite materials), with an uneven change in physical and mechanical properties throughout the volume (synthegran) or with high strength properties (artificially grown superhard ruby and leucosapphire crystals) is either impossible or not economically feasible on modern CNC technological machines. The reason for this is the lack of information about the power parameter, e.g., the machining force and torque. Therefore, the use of the developed adaptive mechatronic mechanism (AMM) module, which implements parametric stabilization of the power machining parameter in an open-loop control system, was an effective solution to this technological problem. An analysis of the issue state in the field of mechatronic and intelligent machines has shown that to date, mechatronics as a science systematically combines mechanics, electronics, and informatics (computer science). Moreover, the term informatics indirectly reflects another component of mechatronics – automation. In this regard, two main methods of automatic control are considered: by deviation in a closed system with feedback and by disturbance in an open system without feedback on the controlled parameter. Examples of open-loop systems with disturbance control, in which the “disturbance compensation principle” is implemented, are given. This method cannot be replaced in the absence of sensors – sources of information about physical processes in technological machines for various purposes, for example, in machine tool building, biomedicine, nuclear and military technology. As a rule, in all these machines there is a reciprocating movement of the working body (tool). The information model of the AMM module presented in the article reflects its main elements and characteristics, including driving forces (electromagnetic and electrodynamic), a ball-bearing screw mechanism, a fixed (unmovable) stator with a field winding and a movable armature with armature winding. The place of this article in the general system of scientific research on the formulated new scientific direction “Mechatronic and intelligent technological machines” is shown. This article is an introduction to this scientific direction, when automatic regulation “by disturbance” is performed in a mechatronic machine, i.e., the principle of disturbance compensation is fulfilled.

“…This can lead to thermal destruction of the metal-polymer part of the composite part. A composite part in which the inner part will be destroyed by temperature will be unusable [41][42][43][44]. The difficulties of casting a metal-polymer specified in Sections 4.2.1 and 4.2.2 require the development of appropriate technological support to eliminate these factors in the production of composite metal-metal-polymer parts.…”

The additive manufacturing of metal parts takes up an increasing number of areas of mechanical engineering, but it still remains too expensive for mass use. Based on the experience in the production of combined metal-metal-polymer forming parts of molds, a new method for the production of composite parts from a metal shell filled with metal-polymer is proposed. As a basis for the study, strength calculations are given by the finite element method for the details of the exoskeleton and a sample of simplified geometry. Comparison of the strength characteristics of parts made of various materials and their combinations showed high strength characteristics of a composite part made of a metal shell and a metal-polymer filler. The metal-metal polymer composite part is distinguished not only by its high strength but also by a significantly lower cost, due to the reduction in the volume of 3D printing with metal. The problems of obtaining composite structures are also discussed. The main problem is the development of a metal-polymer casting technology. The process of filling a thin-walled shell with a metal-polymer causes difficulty.
