Profile Irregularities of Turned Surfaces as a Result of Machine Tool Interactions

Abstract

The paper describes the influence of the machining operation on a surface, which disturbs the projection of the tool profile in the form of its relative movements with respect to the object. The elements of the machine tool undergo constant wear during the machining process, it is therefore important to recognize the effects of their influence on the surface's irregularities. Amplitude-frequency analysis of lateral profiles has been used to evaluate and changes of turned lateral profiles. The results of simulation of radial and axial effects of the machine tool on surface and their spectral components were analyzed. Surfaces obtained in similar machining conditions on lathes operated in various time periods were analyzed spectrally. From the analysis of surface irregularity changes caused by disturbances in movements of the tool against the object, testifying the wear of main machine elements during its operation, the modulated, amplitude-frequency character of changes in surface irregularities of workpiece can be noticed.

The adaptation two-dimensional wavelet transform to assessment the surface roughness produced by face milling

“…To oznacza konieczność znacznie dokładniejszej obróbki oraz ciągłego monitorowania zmian wymiarowo-kształtowych elementów i ich warstwy wierzchniej. Klasyczna metoda analizy SGP z wykorzystaniem transformaty Fouriera jest coraz czę-ściej zastępowana przez rozwiniętą w XX w. transformatę falkową [1,2]. W 1910 r. węgierski naukowiec Alfred Haar po raz pierwszy użył pojęcia falka [3], jednak dopiero lata osiemdziesiąte XX w. przyniosły rozwój tego sposobu analizy danych.…”

On Roughness Measurement by Angular Speckle Correlation

“…In different fields of the industry, the texture and finishing of a surface are of great importance for many applications [1][2][3]. For instance, the capacity of wear, lubrication, resistance to fatigue and external aspect of a material, are examples in which the state of the surface represents an important role.…”

New Indicators Of Burnished Surface Evaluation – Reasons Of Application

“…Spectral methods (Fourier and wavelet transform [5][6][7]15]) are also used for surface analysis. However, it is often desirable to obtain a single indicator as the final result.…”

“…Roughness geometry forms are a result of a geometrically-kinematic representation of the tool point, relative vibrations of the tool and work-piece, plastic deformations and brittle destruction of surface irregularities which depend mostly on the machined materials and the nature of manufacturing processes [1][2][3][4][5][6][7].…”
