“…The main idea facing the creators of this machine was to implement the principle of expanding technological capabilities through the development of replaceable modular spindle heads and a rotary table. Horizontal and vertical spindles, as well as a program-controlled rotary table with a driven worm gear, make it possible to process parts from all sides without remounting the workpieces, as well as closed-loop processing during external and internal slotting [19,20]. At the same time, the use of spindles in this machine with a horizontal and vertical axis of rotation a wide range of replaceable modular designs of angular and slotting heads and an overam support with a set of disk cutters makes it indispensable especially in instrumental and experimental production.…”

“…These units are characterized by the fact that the motion module (linear and/or rotational) is made based on special brushless motors or electric machines with electromagnetic or electromechanical reduction, equipped with sensor systems, measuring transducers, and other electronic elements integrated into electromechanical units [15, 16,17] which, among other things, aim to achieve positive effects in the load -contact -friction -wear chain [18]. Mechatronic modules and mechatronic units [19,20] are the most promising basis for creating relatively flexible progressive high-performance technological equipment, one of the principles of construction of which is the autonomy of manufacturing, assembly, and debugging of autonomous modules and, at the end, of the entire machine, arranged on their basis.…”

The article analyses a wide range of existing technological systems for machining engineering production from special aggregate machines with rigid kinematic connection (control system) to portable machines with mechanisms of parallel structure, which are based on the aggregate-modular principle of the layout. The advantages and disadvantages of such equipment in the modern conditions of manufacturing development are considered in terms of their life cycle in the supply chain and the prospects for further implementation in the machine tool market. The authors analyze the contradictions between the performance and technological flexibility of machining systems and propose ways of resolving these contradictions on the basis of scientific achievements in the field of components, mechatronics, and CALS technologies. On the basis of the performed analysis, the authors suggest a concept and partially implemented a technique for creating various purpose machine-tool systems based on unified technological mechatronic modules considering the tendencies of modern machine-tool production to ensure the sustainability of enterprises under conditions of rapidly changing demand. The prospects of using augmented reality (AG) manufacturing tools for passportization of equipment and its components in order to optimize and green the life cycle of metal-cutting equipment have been substantiated.

“…In one turn of the cutter, the shaft will rotate one circumferential step. When rotating, the WSC performs two functions: the function of the main cutting motion and the function of the form-generating motion, in which the initial straight line of the cutter rack rolls without sliding along the initial circle of the shaft being machined [36][37][38]. In this form-generating motion, the product profile is formed.…”

The monograph deals with the design, calculation and modelling of gear cutting tools. Calculation forms are proposed for the creation of tools structures working by the methods of form-generating and form-copying. Three-dimensional and parametric models of worm wheel hob and worm spline cutters, shaper-type cutters and interlocking disk milling cutters in the environment of integrated CAD KOMPAS-3D and APM WinMachine using specialized applications "CAD Mills" have been built. Calculation forms for determining the geometric, kinematic and design parameters of worm wheel hob for the manufacture of spur and helical gears based on the original contour profile of a standardized gear rack are given. An interactive design of a worm wheel hob in the KOMPAS system was carried out. The design stage of determining the characteristics of the flank-shaped tooth profile modification to reduce the noise level and increase the service life of the gear transmission has been effectively implemented. An interactive procedure for designing a worm spline cutter in the KOMPAS environment for finishing spline shafts is proposed. At the stage of replacing the theoretical profile of the cutter tooth edge with an arc of one circle or tangent arcs of two circles, an express procedure for calculating the magnitude of the error is used. Computer design and research of the shaper-type cutter using the application program "Shaper cutter" in the KOMPAS-3D environment was performed. It is shown that for non-standard shaper-type cutters it is possible to use a standard helical copier of a gear shaping machine if the angle of teeth inclination is 15 0 ±0.5 0 or 23 0 ±0.5 0 . A comprehensive study of interlocking disk milling cutters using the application program "Disk milling cutter" in the CAD KOMPAS contour was carried out. Parametric models of the disc cutter design are built using the syntax of the CAD APM WinMachine. The parametric models of a single-and double-relief tooth, as well as the involute profile of the tooth lateral surface, have been identified.
