KEYWORDS: Light scattering, light scattering methods, image processing and analysis, monolayer abrasive bulk materials, abrasive grains Trizact™ WprowadzenieStan czynnej powierzchni narzędzi ściernych jest waż-nym czynnikiem warunkującym prawidłowy przebieg i uzyskane rezultaty procesu obróbkowego. Wykrywanie wykruszeń i starć ziaren ściernych oraz lokalizacja i analiza zalepień materiałem obrabianym musi być odpowiednio oceniana. Zagadnieniom szeroko pojętej oceny stanu narzędzi ściernych od wielu lat poświęca się wiele uwagi, na co wskazują liczne prace z tego zakresu [1][2][3]. W wielu z nich wymienia się różnego rodzaju metody pomiarowe mogące mieć zastosowanie w tego typu ocenie. Autorzy prac zgodnie podkreślają duże ograniczenia w odniesieniu do pomiarów narzędzi ściernych metodami stykowymi, a jako najkorzystniejsze, w tym przypadku, wymieniają metody optyczne. Ze stosunkowo szerokiej grupy metod optycznych można wydzielić wiele technik mogących mieć zastosowanie w ocenie stanu powierzchni takich narzędzi. Należą do nich m.in. profilometria optyczna [4], interferometria światła białego [5], mikroskopia konfokalna [6], mikroskopia różnicowania ogniskowego [7]. Ważną grupą metod optycznych są również metody wykorzystujące zjawisko rozpraszania światła [8]. Są one z powodzeniem wykorzy-* Dr inż.

“…The subject literature includes numerous publications concerning the operations of grinding nickel-based alloys using grinding wheels with Al 2 O 3 grains (white fused alumina 99A [2,9,[17][18][19][20][21], microcrystalline sintered corundum [18,[22][23][24]), SiC [9,17], cubic boron nitride cBN [2,9,14,17,18,[25][26][27][28][29][30][31], and diamond grains [2,25,26,28,29]. When analyzing bonds used in grinding wheels meant for grinding nickel-based alloys, it may be observed that resin bonds are characterized by too low a profile stability [29].…”

“…The cBN grains are characterized in most cases by more favorable grinding results and a longer durability period [26,29]. In flat or internal cylindrical grinding processes, in which there are no such high expectations concerning the grinding wheel profile durability, grinding wheels with ceramic bond are used most often [2,9,10,14,[17][18][19][20][21][22][23][24]31].…”

The following article examines the influence of glass-crystalline bond in grinding wheels with grains made from microcrystalline aluminum oxide, and specifically its effect upon the values of selected operational indicators in the process of traverse internal cylindrical grinding of surfaces made from Inconel® alloy 600. The experimental test results obtained showed that changes in the bond phase composition, including its microstructure and volume share in the grinding wheel, has significant influence upon the workpiece surface roughness, grinding power, and other basic phenomena within the grinding zone. It was proven that the heat and physicalmechanical properties of the bonds have considerable influence on the mechanism of the grinding wheel components (abrasive grains and bond bridges) wear mechanisms. The phenomena occurring in the area of contact between the grinding wheel active surface and the workpiece surface requires on, among other things, the temperature at which the bond softens, initial bond hardness, the critical coefficient of grain strain intensity K Ic , the crystalline phases generated, and the volumetric share of the amorphous and crystalline phases in the bridges binding the abrasive grains.

Numerical and Experimental Investigation of Plastic Interaction Between Rough Surfaces

The paper presents a dry friction model considering plastic interactions described by the Oxley equations. The model differs clearly from those published by Oxley due to the fact that it includes a statistical analysis of rough surface interactions. The contact of a single asperity is analyzed in a 3D-not 2D-space. The results of this analysis are further extended to the contact of two rough-surfaces by accomplishment of an appropriate summing (integration) of individual elementary forces of friction and pressure occurring in discreet contacts. In the case of papers based on the Oxley model, their authors analyze the contact of a single asperity with a plane and thus compute the macroscopic friction coefficient. On the basis of the achieved mathematical model of dry friction, the friction force was determined and consequently, the friction coefficient. In order to verify theoretical speculations, an experimental test was carried out in the system consisting of a steel disk with a galvanized coating and a steel pin. The results of experimental tests comply with the solutions achieved via a computer simulation. The resistance to motion results mainly from plastic deformations, which in turn result in adhesion tacking. Among investigated galvanic coatings, the highest motion resistance was revealed by a nickel coating, whereas the lowest one was revealed by a silver coating.
