The creation of modern highly efficient felting equipment with different functional purposes is a necessary condition for the progressive development of various branches of industry in Ukraine (engineering, light, pharmaceutical, chemical industry, etc.). The competitiveness of products also depends to a large extent on the efficiency and productivity of finishing parts after their molding. In light industry, small typical parts are widely used, the quality of which is determined by the organoleptic method, and the shaping of which can be realized by casting or by mechanical processing or stamping. All these parts, after forming, need to perform time-consuming finishing felting technological operations, the essence of which is volume processing with a technological environment for the possibility of separation and separation of parts from sprues, burrs, burrs; rounding of sharp edges; surface grinding and polishing; surface cleaning from corrosion products, etc. Sometimes up to 80% of the total technological time is spent on the finishing technological operations. In the vast majority, for the implementation of such technological operations, rolling rolling drums or vibrating equipment are used, which are characterized by low performance of technological operations. Increasing the efficiency of processing during the execution of finishing technological operations of felting can be achieved with the use of felting equipment with working containers that perform complex spatial movement. The synthesis of rational statically determined spatial mechanisms of machines for processing parts with various design features has been performed. Unified requirements and approaches have been developed for the synthesis of statically determined spatial mechanisms without the passive connection of the rolling machine with the complex spatial movement of the working container. An analytical study of the geometric and structural parameters of all synthesized statically determined spatial mechanisms was carried out. Obtained mathematical dependencies for the possibility of rational calculation of geometric and constructive parameters of spatial mechanisms. General approaches for complex analytical research of synthesized statically defined spatial mechanisms from the point of view of calculating their geometric and structural parameters have been developed. Designs of actuators have been developed, which ensure the transfer of rotary motion to the drive shaft of the machine, which at the same time performs additional reciprocating movement, the hinged components of these actuators have been synthesized. Strength studies of the developed designs of felting machines with complex spatial movement of working containers without passive connections in their kinematic chains were carried out, graphical regularities of the maximum values of reactions in all kinematic pairs of felting machines depending on the change in the corresponding geometric parameters of the moving links were obtained. For the first time, analytical and experimental studies of the separation of metal parts from showerheads (on the example of metal parts of a "zipper" lock) in a rolling machine, the working capacity of which performs a complex spatial movement, were performed. Mathematical dependencies were obtained analytically for calculating the minimum time required to perform the technological operation of separation of metal parts from showerheads in a container that performs complex spatial movement. The influence of the modes of movement of the working array, the volume of filling the container, as well as the shape and geometric parameters of the metal castings of the "zipper" lock on the intensity of the separation of the metal parts from the spouts was experimentally investigated. It has been established that the most intense separation of parts from the sprues occurs when the waterfall mode of movement of the working mass is implemented, when the working capacity is filled by 50% – 75% of its total free volume, and also that the branched complex shape of the castings requires significantly longer processing time. Productivity when processing metal parts using machines with complex movement of the working capacity can be 10 times higher than the productivity when processing parts using rolling machines with rotating drums. In particular, the technological process of separating the metal parts of the "lightning bolt" lock from the showers using the developed design of the rolling machine with complex spatial movement of the working capacity was accepted for implementation at PrJSC «Molniya». Also, the results of scientific research were implemented in the educational process of three higher educational institutions – Kyiv National University of Technology and Design, Open International University of Human Development «Ukraine» and Fastiv Automobile and Road Technical College TSO of Ukraine.
