Abstract
Roughness measurement is of highlighted importance in production for describing the quality control of manufacturing processes for the functional, tribological, etc. properties of the surfaces of parts. In the last 15 years or so the areal roughness studied on topographies has also become more common, as it provides a more accurate and detailed characterization of the surfaces. However, with relatively little experience and different technical conditions, topographies are analyzed differently. Sometimes 3D topography is used only as an illustration; however, spatial roughness measurement can provide much more information. The effect of measurement speed and point density during roughness measurement on the areal roughness was investigated using a confocal chromatic sensor.
Highlights
Surface roughness is the most commonly used indicator to describe surface quality [1]; roughness measurement has an emphasized importance in production, which, serves as a tool to describe operational, tribological, and other properties in addition to maintaining quality control of production processes
The aim of the study is to analyze the effects of the roughness measurement setting options on the values of the areal roughness parameters with the confocal chromatic sensor of the roughness measuring device
The roughness of a topography is a topic increasingly often being studied in industry and in different research areas; areal roughness is examined differently in terms of measurement settings and method of evaluation
Summary
Surface roughness is the most commonly used indicator to describe surface quality [1]; roughness measurement has an emphasized importance in production, which, serves as a tool to describe operational, tribological, and other properties in addition to maintaining quality control of production processes. In the last decade and a half, the areal roughness studied on topographies has become more widespread, as it provides a more accurate and detailed characterization of the surfaces than profile examination. In high-speed face milling of magnesium alloy with a PCD tool, the effect of machining parameters (vc, fz, ap) on the surface roughness was investigated [1]. The profiles were examined with L-filter (2.5 mm) and Gaussian filter, though the method of evaluation of the topography was not reported. Height areal roughness indices were examined in correlation with the cutting speed. The literature review shows that topographies are examined in different ways in terms of size of measured areas, measurement settings and evaluations, so it is not possible to accurately compare machined surfaces
