“…Важным ориентиром в этих исследованиях являются трибологические характеристики и износ рабочих поверхностей керамических деталей и инструментов [2][3][4][5][6][7]. Известно, что на процессы трения и износа значительно влияет морфология поверхностного слоя керамики с присущими ей многочисленными дефектами, образовавшимися при алмазном шлифовании [8][9][10]. Однако определить количественные показатели взаимосвязи качества шлифованной поверхности с трибологическими характеристиками керамических деталей не представляется возможным из-за многообразия морфологических рисунков и разнородности поверхностных дефектов, а также весьма сложной физической природы этой взаимосвязи [11,12].…”

It was established that the parameters of the grinding mode of Al2O3--TiC-ceramics significantly affect their tribological characteristics, the intensification of the regime leads to an increase in the tangential force and friction coefficient, the width of the friction track and the width of the wear area. Using the identified interrelations, technological recommendations for rationing the quality of ceramic parts at the design stage, which increase the operational reliability of ceramic products, have been developed.

“…In order to investigate the material removal mechanism of an aluminum oxide-carbide ceramic, Tanovic et al [1] applied a micro-cutting process with a single diamond grain. Besides crushing of ceramic grains, they observed the occurrence of plastic deformation followed by median cracks (caused by the penetration of the grain) and lateral cracks (initiated during unloading).…”

Among the alternatives to reduce the application of cutting fluid in machining industry, minimum quantity lubrication (MQL) technique has been promising, although it can impair cooling properties and the ability of the fluid to penetrate the cutting region. In order to further reduce the quantity of oil and to improve the characteristics of the cooling lubrication method, this work aims to compare the effect of MQL with different ratios of oil/water (1:1, 1:3, and 1:5) on the performance of plunge cylindrical grinding of alumina. Lubricating effect and effective penetration of fluid in the cutting zone are considered the most relevant factors. The lowest surface roughness value was obtained with the application of conventional flood cooling, followed by MQL 1:1. In comparison to conventional MQL technique, reduced surface roughness and grinding wheel wear could be obtained by applying MQL with water.

“…The basic mechanism of EDM process has been studied for many years but it is not yet completely understood and is still an active research topic. Various researches in the Electrical Discharging Grinding (EDG) of PCD had been performed in the past decades [2,3]. Thoe et al [4] examined the edge quality of various grades of PCD cutting tool blanks produced using an in-house EDG machine.…”

The poor electric conductivity of polycrystalline diamond (PCD) makes it difficult to machine with the conventional EDM process. Inappropriate selection of parameters of the power generator and the servo system leads to unstable working condition and low material removal rate. This paper introduces a method to find optimal parameters in the Electrical Discharge Grinding (EDG) of PCD materials with Taguchi method. The theory and detailed procedures are presented, experimental results are analyzed. The optimized configuration was validated through confirmation tests.
