Документ Roughness investigation of single and double cutting marks on face milled surface(Національний технічний університет "Харківський політехнічний інститут", 2023) Nagy, Antal; Kundrak, JanosIn machining with defined cutting edge tools, in some rotational tool processes (e.g. face milling) the tool edge may scratch the surface of the workpiece one more time, depending on the cutting conditions, during one revolution of the tool. As a result, the topographies with single or double cutting marks will be different from each other. The deviation, depending on its size, can also affect the functional performance (e.g. friction conditions) of the operating surfaces. In this article, face-milled topographies created with a symmetrical setting and with single or double milling marks are compared according to the magnitude of the roughness and the degree and nature of the inhomogeneity.Документ Investigation of face milled surface topography on C45 workpiece assuming movement at 30° and 60° to feed direction(Національний технічний університет "Харківський політехнічний інститут", 2023) Nagy, Antal; Kundrak, JanosWhen surfaces with anisotropic texture are moved in different directions related to their assembled counterpart during operation, the friction conditions change, as they are determined by the lay of the topographies. In the article, contributing to the exploration of this characteristic, we analyze the inhomogeneity of the topography on a face milled plane surface with a symmetrical setting in sections at an angle of 30° or 60° to the feed direction. Roughness profiles are recorded at 13 pointslocated equidistantly from each other in each measurement plane, and the degree and distribution of the roughness deviations are determined on the surface.
