“…Numerous other publications deal with planetary-type finishing equipment and technologies, however, the possibilities of implementing the vibration-driven mechanisms for conducting the finishing operations are currently of significant interest among scientists, engineers, and technologists. The present research continues the authors' previous investigations [14]- [17] dedicated to the development and implementation of vibratory finishing equipment. This paper is focused on developing a special control system for the solenoid-type actuators of the vibratory lapping-polishing machine and providing a circular trajectory of the working member in order to ensure the machining (lapping, polishing) uniformity at each point of the surface being treated.…”

Vibratory technological machines are widely implemented in various branches of industrial, manufacturing, and mechanical engineering. Particularly, such equipment can be effectively used while conducting finishing technological operations, e.g., lapping and polishing of different machine parts. The present paper is focused on developing the control system for the novel design of a vibratory lapping-polishing machine driven by six solenoids. The main purpose consists in providing the circular trajectory of the working member and ensuring the machining uniformity at each point of the surface being treated. In such a case, it is proposed to actuate the solenoids with the specified time shift depending on the forced frequency needed to be provided. The duration of the signal actuating the solenoid is equal to one-sixth of the total duration of a cycle (period) of the working body oscillation. The corresponding control approach is developed and simulated in the Tinkercad application, while the control system is designed based on the Arduino software and hardware. In addition, the laboratory prototype of the vibratory lapping-polishing machine and the corresponding control system are implemented in practice. The performed experimental investigations substantiate the possibilities of generating the circular oscillations of the working member of the vibratory lapping-polishing machine. The obtained results may be useful for engineers and technologists dealing with control systems of various vibratory technological equipment based on electromagnetic and solenoid-type drives.

“…The actuators based on linear electric motors are mainly applied in precise manufacturing processes, robots, materials machining centers, additive manufacturing, and laser cutting for working tools positioning and parts moving (Gieras [18], Korendyi et al [19,20]). The best linear electric motors for such applications are permanent magnet (PM) linear synchronous motors (LSM).…”

Standard hydraulic breaking hammers are widely used for crushing oversized blasted materials and concrete structures demolition in industry. These hammers, installed in on-surface working excavators or stationary manipulators at the dumping points of underground conveyors, provide the required limited sizes of bulk materials and enable the safe operation of other equipment (screens, crushers). In parallel, hydraulic hammers have an alternative—fully electric hammers. This paper aims to review existing linear electric motor (LEM) hammers as an energy-saving and eco-friendly solution in industry. Global market analysis is presented with potential branches of LEM hammers. Several aspects for implementation—design optimization, dynamics simulation, machine control, and performance estimation—are considered. Different case studies for LEM-hammer application are given. The preliminary measurements are demonstrated on the electric hammer of Lekatech Company, which is intended for the mining industry and construction demolition. Experiments showed that depending on the impact frequency, type of rock, and shape of the crushing tool, the time to fracture varies significantly. Optimal parameters exist for every case, for which adjusting requires online hammer control.

“…The initial design of the electromagnetically-driven vibratory lapping machine was proposed in [13]. The dynamics of the lapping process is thoroughly studied in [14,15], and the corresponding experimental investigations are analyzed in [16]. Based on the authors' previous investigations, the enhanced methods of generating the reciprocating motion and plane oscillations of the working member (lap, polisher, grazer, etc.)…”

Vibratory treatment is widely used in various industries for performing finishing technological operations, e.g., lapping, polishing, glazing, strengthening (hardening), etc. The problems of maximizing the treatment accuracy and performance of vibratory technological equipment provide the necessity of optimizing the motion trajectory (path) of the corresponding working member. The main purpose of these investigations is to substantiate the possibilities of generating the translational (reciprocating) motion and plane (plane-parallel) oscillations of the working members of vibratory lapping-polishing machines. The research methodology consists of the following stages: substantiating the ideas of improving the vibratory lapping-polishing machines; designing the dynamic diagrams of the machines’ oscillatory systems; developing the mathematical models to describe their dynamic behavior; numerical modeling of the machines’ motion conditions. The obtained results present the possible motion trajectories (paths) of the working member (lap, polisher, grazer, etc.). The main scientific novelty of these investigations is substantiating the idea and possibilities of implementing various motion conditions of the working member for adjusting the vibratory lapping-polishing machine in accordance with the technological requirements, as well as for increasing the wear-out period and durability (normal operating period) of the working member. The obtained results can be used for improving the performance and accuracy of similar vibratory lapping-polishing machines.
