“…An overview on previous studies on the manufacturing of material measures has already been presented by some of the authors [12,22,23]. The methods range from ultraprecision cutting processes, such as micro-milling [24][25][26][27] to classical processes from microtechnology, such as focused ion beam [28] or lithographic methods [29].…”

The calibration of areal surface topography measuring instruments is a topic that is currently under discussion in international standard committees and a specification standard that defines the so-called ‘metrological characteristics’ has been published. For the broad industrial adoption of the metrological characteristics for calibration, however, clear and easy-to-apply calibration guidelines are required. Thus, a single-sample calibration artefact has been developed which allows the determination of the standardised metrological characteristics. In order to promote the adoption of the metrological characteristics calibration framework, measurements of the material measures with different instruments have been conducted and the results are presented. We report early work on the uncertainty of the comparison results and discuss systematic deviations between the various surface topography measuring instruments.

“…This toolpath was designed based on a point cloud representing the target surface topography. For the control dataset (G-Code) of the examined material measures according to ISO 25178-70 a spacing of 4 μm between two tool paths of the meander was determined to be a suitable value for first tool T1 [38]. However, since the wavelengths of the target geometry of the Sk material measure are smaller than for the material measures according to ISO 25178-70, the distance between two tool paths has been reduced in this study.…”

The calibration and verification of areal surface topography measuring instruments is usually performed with artificial geometries that do not correspond to a practical measuring task like gratings or step height artefacts (ISO 25178-70:2014). While these processes have a sufficient process capability to meet the requirements of many industrial measurement applications, there are more and more applications that require small tolerances, which results in the necessity of a performance verification that is more closely related to the later performed measuring task. With a model-based design approach it is possible to design material measures based on component surfaces for an application-oriented performance verification. The initial point is a measured dataset, which is evaluated and virtually transformed in a way that on the one hand the target properties are met, but on the other hand also the functional properties of the surface that are relevant for the specific application are preserved. Based on the subsequent application of virtual manufacturing and measuring processes, also impacts from these processes can be considered in the design of the verification sample. In this study, we extend the basic approach that has been developed for the design of profile material measures e.g. with the manufacturing principle of ultra-precision turning (Seewig, Eifler, Schneider, Aurich Proc. CIRP 45 (2016), 259-262; Eifler, Schneider, Seewig, Kirsch, Aurich Eng. Sci. Technol. 4 (2016) 1993-2001. Seewig, Eifler, Schneider, Kirsch, Aurich Surf. Topog.: Met. Prop. 4 (2016) 024010. Eifler (2016)). to areal material measures and a corresponding manufacturing principle of micro-milling. With the model-based design approach, component surfaces are used to determine two different material measures that feature defined values of the surface texture parameters Sa, Sq, Sk, Svk, Spk as a case study. It will be shown that the areal surface texture parameters can be mapped to the designed material measures that enable a practical performance verification.

Az érdességmérési beállítások hatással lehetnek a forgácsolt felület mért 3D-s topográfiai értékeire. E hatásokat a kutatók kevésbé vizsgálták, pedig az adott megmunkálás forgácsolási, elsősorban kinematikai viszonyainak függvényében ennek (a mérési beállítások) figyelmen kívül hagyása a pontosságát és reprodukálását akár jelentősen is befolyásolhatja. Ezért indokoltnak láttuk a mérési beállítások hatásának feltárását és ezen vizsgálatok eredményeinek elemzését. A cikkben homlokmart síkfelületen vizsgáltuk a mérőrendszeren beállítható értékek – a mért pontok távolsága és a mérési sebesség – hatását az érdességi paraméterekre.
