“…2. Czynniki wpływające na proces generowania chropowatości powierzchni podczas frezowania wg [2] Autorzy pracy [6] twierdzą, że chropowatość powierzchni kształtuje proces obróbki poprzez stereometryczno-kinematyczne odwzorowanie krawędzi ostrza na powierzchni materiału obrabianego, co bezpośrednio związane jest z parametrami skrawania. Uwzględniają oni również czynnik zakłócający idealny proces usuwania materiału w postaci przemieszczeń względnych pomiędzy narzędziem a przedmiotem obrabianym, które są wynikiem błędów wrzeciona i drgań maszyny (rys.…”

ANALIZA CZYNNIKÓW WPŁYWAJĄCYCH NA STRUKTURĘ GEOMETRYCZNĄ POWIERZCHNI PODDANYCH OBRÓBCE SKRAWANIEM StreszczenieArtykuł zawiera przegląd odnalezionych w literaturze zestawień czynników mających wpływ na proces generowania struktury geometrycznej powierzchni poddanych obróbce skrawaniem. Na podstawie przeprowadzonej analizy literatury i własnych doświadczeń autorzy opracowali nowe zestawienie czynników, które oddziałują na proces kształtowania struktury geometrycznej powierzchni. Ta klasyfikacja uwzględnia 32 czynniki podzielone na pięć grup związanych z obrabiarką, narzędziem i właściwościami materiału obrabianego, ze zjawiskami obróbkowymi towarzyszącymi procesowi skrawania oraz z czynnikiem ludzkim. Słowa kluczowe: obróbka skrawaniem, chropowatość powierzchni, parametry procesu skrawania THE ANALYSIS OF FACTORS IMPACTING THE GEOMETRICAL STRUCTURE OF MACHINED SURFACES AbstractThe article presents an overview of comparisons of factors impacting the process of generation of the geometrical structure of machined surfaces, as found in the literature. On the basis of the conducted analysis of literature and own experiences, the authors have developed a new comparison of factors impacting the process of forming of the surface geometrical structure. This classification includes 32 factors, divided into five groups related to the machine tool, the tool and the properties of the workpiece, with the machining phenomena accompanying the cutting process, and with the human factor.

Abstract:The paper presents a novel approach for modelling and simulation of the surface generation in the potassium dihydrogen phosphate (KDP) crystal fly cutting machining process in the macro, micro and nano scales, in order for the evaluation specifications in different spatial frequency region. The main influential factors of surface topography in different scales are discussed and modeled by different methods. The simulations take into account all the intricate aspects of the machining process affecting the surface topography and texture formation, such as the straightness of the slide, the dynamic performance of the machine tool, the cutter profile.This method can realize the machine tool performance and machining parameters optimization by the surface prediction and detection. The numerical calculation (NC) and the finite element (FE) method are used in the macro and micro scales. Molecular dynamics (MD) simulation is used in the nano scale. Furthermore, the proposed systematic modelling approach is verified by cutting trials, which provide the coincident results of the simulated surface topography.

“…To get the connection of the tool path and the machined surface, several literatures focuses the surface topography generation process. Cheung and Lee [1]- [2] used the digitizing oscilloscope to record the relative displacement between the tool and the workpiece. After been analyzed by Fast Fourier Transform (FFT), the main frequency and amplitude of vibration reconstructed the tool deviation from ideal position.…”

In nano/micro cutting process, the surface quality is heavily dependent on all the dynamic factors in machining including those from the material, tooling, cutting parameters, servo accuracy, mechanical structure deformation, and non-linear factors as well. The machined surfaces are generated based on the tool profile and the real tool path combining with the various external and internal disturbances. To bridge the gap between the machining conditions and the surface quality, the integrated simulation system presented involves the dynamic cutting process, control/drive system and surface generation module. It takes account all the intricate aspects of the cutting process, such as material heterogeneity, regenerative chatter, built-up edge (BUE), spindle run-out, environmental vibration, and tool interference, etc. The frequency ratio method is used to interpret the surface topography and texture formation. The proposed systematic modelling approach is verified by the cutting experiment.
