“…It is known that to grind the teeth in gears by copying, they are placed almost vertically in the grinding area and ground [2,6,15]. It has been established that, analogously to shaped turning surfaces, the actual cutting depth determined in the vertical direction in a tooth grind with copying varies along the involute profile of the tooth [9,13].…”

Grinding of machine and responsible equipment parts, gear surfaces with various purpose shapes provided in the construction of tools, as well as gear surfaces provide high processing accuracy and productivity. At this time, the positioning angles of the elemental regions of the workpiece to be grinded in the cutting zone differ from each other, the actual cutting depth varies along the shaped profile, and due to inheritance, similar processing errors occur on the grinded surface, processing efficiency is not ensured. In this work, the mechanism of the change of cutting depth during grinding of shaped surfaces by copying is investigated, the direction of ensuring its maximum regularity along the shaped profile is determined, the issue of improving the quality and efficiency of grinding is solved by using the technological possibilities of the operation, despite the reduction of the number of working trips, grinding should be carried out in relatively light modes and it is possible to ensure similar quality of grinding. By placing the tooth of the gear to be grinded at an angle the roughness of the processed surfaces during grinding is smaller compared to tooth grinding with the existing method and the quality is correspondingly high.

Wear is the leading cause of nozzle failure. The durability of the nozzle is affected by the material it is made from. Traditional materials are ceramics, stainless steel, brass, and polymers. One of the possible ways to improve the wear resistance of polymer nozzles is through the incorporation of dispersed fillers into them. This paper presents the results of testing polymer composites for their chemical resistance to pesticides, examining the effects of different types and amounts of fillers on the chemical and abrasion resistance. When silicon carbide was used as a filler, the strength increased by 30.2%. The experiments on chemical resistance to pesticides revealed that the nature, shape, and volume content of filler particles do not significantly affect the resistance of the compounds obtained. Tests on hydro-abrasive wear have shown that graphite and silicon carbide are effective fillers capable of reducing wear by up to 7.5 times. Based on previous research, it is recommended to use a composite compound with 15% volume of silicon carbide for nozzle manufacturing.

“…Анализ производства современных малогабаритных зубчатых (кинематических) передач позволил выявить следующие особенности. В основном проектируют и изготавливают одноступенчатые и малогабаритные передачи из конструкционных полимерных композиционных материалов и преимущественно мелкосерийными партиями [2]. Достаточно широко стали использовать для изготовления таких зубчатых передач 3D-принтеры в основном в индивидуальном производстве [3][4][5].…”
