Evaluation of Capability of Roughness Measuring Device

Abstract

The aim of this paper is the evaluation of capability of roughness measuring device SURFCOM 1900SD3. After elaboration of theoretical part of this paper, which is focused on literary study in the evaluation of measuring devices, experimental work was proposed in which conditions for measuring and evaluation of measured data are defined. After this definition of measuring conditions, experimental work was performed. For evaluation of roughness measuring device, 30 measurements on the gauge sample with exactly determined value of arithmetic mean deviation of the profile Ra was proposed. Evaluation was carried out using statistical methods, namely coefficients to define measuring device capability. The work contributed significantly to the assessment of capability of roughness measuring device SURFCOM 1900SD3, since it was required by practice.
