“…The surface of the ceramic parts has a specific relief due to the impact of diamond grains and wheel binder friction on the sintered ceramic surface and the local plastic deformation, which occurs during high-speed heating of the ceramic surface areas and their rapid cooling [13]. Numerous technological defects reduce the efficiency of CCT operation and hinder the industrial use of the tool [14][15][16]. Therefore, the leading industrial application of CCT is high-speed lapping continuous machining with small cut thicknesses.…”

The specific features of the destruction of tool ceramics, associated with structural heterogeneity and defects formed during diamond grinding, largely determine their reduced reliability (dispersion of resistance). This is most pronounced at increased heat and power loads on the contact surfaces and limits the industrial application of ceramic cutting tools. The surface layer of industrially produced Al2O3+TiC cutting inserts contains numerous defects, such as deep grooves and torn grains. During the milling of hardened steels of the 100CrMn type with increased cutting parameters, the “wear–cutting time” curves have a fan-shaped character with different wear rates. The resistance of the tool that was taken from one batch before reaching the accepted failure criterion has a significant variation in values (VarT is 30%). The study is aimed to evaluate the influence of the condition of the surface layer of Al2O3+TiC inserts processed by various types of abrasive treatments, such as diamond grinding, lapping and polishing, on the quality of the (TiAl)N and (TiZr)N coatings and the reliability of prefabricated end mills. The obtained “wear–cutting time” curves are characterized as closely intertwined bundles. The coefficient of resistance variation (the tool’s reliability) decreases by more than two times (14%). This can be used further in coating development to improve the performance of CCT.

“…Многие вопросы, связанные с надежностью этой подсистемы при использовании режущих инструментов из быстрорежущей стали и твердого сплава, достаточно проработаны и реализованы в нормативных документах и технологических рекомендациях [5]. Однако проблему надежного функционирования подсистемы резания в случае использования керамических инструментов (КИ) решить не удается из-за специфического поведения керамики под действием экстремально высоких нагрузок [6][7][8][9][10][11]. Из-за неудовлетворенности потребителей КИ единственной эксплуатационной характеристикой -средней стойкостью -необходима разработка комплекса характеристик, способных достоверно оценить надежность этих инструментов.…”

“…Seshadri and Srinivasan 10 have obtained two and three Weibull parameters from the statistical strength distribution of ceramics when fracture is governed by either surface flaws or volumetric flaws. Vigneau and Bordel 11 have shown the reliability of ceramic cutting tools in both turning and bending tests.…”

An approach to optimisation of the polishing of ceramic blocks with multiple performance characteristics, based on reliability analysis, Taguchi and grey methods, has been studied. Speed, load, diamond size and concentration are optimised polishing parameters when the performance characteristics, which include Weibull modulus and removal rate, are taken into consideration. Optimisation with multiple performance characteristics is found to be the highest speed and greatest load, and diamond particles of 3 mm size and 45% concentration. Analysis of variance shows that the most significant polishing parameters are load (52 . 46%) and speed (33 . 09%), followed by diamond particle size (8 . 21%) and concentration (6 . 24%). Experimental results have shown that the multiple performance characteristics of polishing of ceramic blocks are greatly improved through this approach.
