“…It should be noted that the configuration of such a cutting tool having the point angle of the blade b = 55°is associated with certain difficulties to obtain low roughness on the front and back surfaces and minimize the defects on the main cutting edge. To improve the sharpening quality, the electro-diamond grinding method has been used allowing to machine the high-strength materials with high coefficient [16][17][18][19][20][21][22].…”

The article presents the characteristics of polymer composites processing, in particular, the wear process of the cutting tools. It is revealed that composite materials are difficult for machine cutting and require to apply a high-strength tool material and selection of optimal cutting mode. The important task is to reduce the cutting tool wear speed. To solve the problem, the experiment with a variation of the cutting mode was conducted, and the results showed that the tool wears faster at the high cutting speed and cutting depth. With the cutting speed increase, the intensity of the growth of the wear chamfer increases significantly, and therefore, when setting the cutting conditions, one should be guided by a rational combination of the operability of the cutting tool, the quality of the machined surface, and the processing capacity. These studies have also allowed to establish that the uneven wear process is uneven throughout the length of the cutting edge due to the layer structure of the composite.

“…), or lack of one carbon atom in a crystal lattice. Surely the defects can develope further under high temperature and pressure in the cutting zone [24][25][26][27][28]. It seems plausible that synthesis of defect-free diamonds might be one of the promising ways to prevent loading of metal-bonded grinding wheels [21,[29][30][31].…”

Abstract. Defects arising in diamond crystals during their synthesis, give rise to the formation of more complex defects that arise in the operational process of diamonds themselves. In case of external action these defects have immediate strong effect on operating characteristics of devices, products or tools containing diamonds. When external action these defects and have immediate strong effect on production characteristics of devices, products or instruments containing diamonds. This is particularly manifested in the grinding of tough, ductile materials based on aluminum, magnesium or titanium. Developed on the basis of modern digital technology and molecular dynamics visualization method allows to show it at the atomic level. The problems of practical application of the combined electric diamond grinding are examined. Experiments were conducted on the grinding tool materials with metal-bonded diamond grinding wheels.

“…In this regard, the manufacturing industry is particularly interested in the development of a new type of technological equipment that allows the implementation of methods for modifying the surface layers of parts by processing them with concentrated power sources [12][13][14][15][16]. Local and ultra-high-speed thermal effects allow for the obtaining of higher values of hardness, strength, and viscosity, due to the formation of a highly dispersed metastable structure on the surface of the parts with a much higher dislocation density compared to volumetric machining and traditional approaches to surface hardening [5,[7][8][9][10][11][12]. The development of high-frequency heating technology related to the use of radio frequencies, as well as to the miniaturization of inductors and equipping them with ferrite cores, has led to the emergence of a new method, i.e., high-energy heating with high-frequency currents (HEH HFC).…”

This paper presents the results obtained when combining mechanical and surface-thermal operations, using the same process equipment. The paper also demonstrates the possibility of implementing high-energy heating with high-frequency currents, and proposes using an integral temperature–time characteristic as the main parameter to specify surface quenching modes. The numerical values of the integral temperature–time characteristic are to be related to the processing modes and the depth of hardening. The experiments confirmed that an increase in the capacity will be commensurate with an increase in power consumption when a volumetric heating scheme (with a hardening depth of 0.5 mm) is realized. However, during the realization of a volumetric heating scheme, when the 0.7 mm depth of the hardened layer is at the boundary of the “hot” depth of the current penetration into the metal (the beginning of the intermediate heating scheme), the increase in the processing capacity will be higher than that in power consumption.
