“…The investigations were carried out on AS6 diamond grits of size 160/125 which were synthesized in the Ni-Mn-C and Fe-Si-C systems [10]. The powders were separated in a magnetic field of variable strength to produce fractions that differ in specific magnetic susceptibility.…”

The paper addresses physical mechanical characteristics of AS6 diamond grits synthesized in the Ni-Mn-C and Fe-Si-C systems. These diamonds vary in magnetic properties, mechanical charac teristics, amount of impurities and intracrystalline inclusions. The authors demonstrate a potential of using the results of investigation of morphometric characteristics of dimond powders for their efficient application in grinding tools. A relationship has been established between these characteristics and the tool wear resistance in diamond grinding.

“…З-поміж технологічних методів заслуговують на увагу застосування антиабразивних покриттів, оброблення поверхонь і раціональне армування крицевих деталів [53,54]; особливо це стосується захисту козирків лап і тильних частин шарошок доліт [55][56][57]. Використовуючи теоретичні підходи на стадії розробки складів матеріялів і покриттів та зміцнювальних технологій [58][59][60] і враховуючи технологічну спадковість та якість оброблення металевих поверхонь під час виготовлення [61][62][63], можна забезпечити надійне функціонування бурових інструментів упродовж життєвого циклу [64]. У цьому напрямі перспективним є використання композитних [65], спеціялізованих гнучких [66], металевих [67] і функціонально ґрадієнтних [68,69] покриттів.…”

торами під час проведення планованого експерименту були тип і діяметер тришарошкового долота та витрата промивальної рідини (води). Планований факторний експеримент було проведено в блоках пісковику Городищенської світи твердістю у 1440 МПа. За результатами експерименту побудовано рівняння багатофакторних емпіричних моделів енергії EНЧК і EЗК коливань динамічного складника обертового моменту на долоті та проведено аналізу впливу на цю енергію зовнішніх незалежних чинників.Ключові слова: сталеве долото, емпіричний модель, енергія випадкового процесу, спектральна густина, енергія низькочастотних коливань динамічного складника обертового моменту на долоті, енергія зубцевих коливань динамічного складника обертового моменту на долоті, змінний чинник.In order to establish multifactorial empirical energy models of low-frequency (EНЧК) and toothed (EЗК) oscillations of the dynamic component of the torque on the bit, experimental studies are conducted at the stand of the Ivano-Frankivsk National State University of Oil and Gas, using the method of rational planning of experiments. According to this method, the combination of variable factors, which include the axial static load Fст, bit rotation frequency n, stiffness C, and damping coefficient β of the drilling tool, occurs only once. The studied parameter is the amplitude value of the dispersion (energy) at local maxima, which are fixed on the low-frequency and jagged fluctuations of the spectral density (energy spectrum) of the internal structure of the dynamic component. General multidimensional functions are represented by the product of individual dependences on variable factors:where Bср is the average value of the numerical coefficient for the set of all experiments. Constant factors during the planned experiment are both the type and the diameter of the three-layer bit and the consumption of flushing fluid (water). The planned factorial experiment is carried out in blocks of sandstone of the Horodyshche strata with a stamp hardness of 1440 MPa. According to the results of the experiment, the equations of multifactor empirical models of energy EНЧК and EЗК fluctuations of the dynamic component of the torque on the bit are constructed, and the influence of external independent factors on this energy is analysed.

The article has grounded the necessity to develop an empirical power dependence of cutting modes influence on part surface roughness obtained during thread grinding. The calculations were carried out for grinding of parts made of steel and hard alloy. There have been developed a relation of part material properties, grinding wheel options, lubricating and cooling liquid (constant for concrete conditions of thread grinding), depth of cutting (thickness of a grinded layer per path), revolutions of a part and a wheel, longitudinal feed refer to obtained roughness. It has been stated that components of the grinding mode contribute in roughness values in different way, in particular they are arranged in the ascending order as follows: grinding depth, rotation speed, and detail’s diameter.
