Shaping the surface texture of the ring-type test samples used for evaluation of the surface roughness by ARS method based on imaging and analysis of the scattered light

摘要

Determining the metrological parameters of a newly developed measurement system often requires conducting proper test procedures, using typical commercial or specifically dedicated standards, alongside test samples. This paper presents the various stages in the preparation and measurement of ring-type test samples prepared for the testing of hybrid systems for non-contact simultaneous assessment of surface texture and dimension. Machining of the samples was carried out using a small bench-type SK-1 lathe, whereas the finishing process using a wide range of abrasive sheets (grain Nos. 200-2500) as well as micro-abrasive (diamond) and polishing (Al_2O_3-based) pastes. The effects of machining were verified by stylus profilometry and white-light interferometry. All measurement data obtained was analysed by TalyMap Platinum 4.0 software. The results of the analysis confirmed the appropriateness of machining in accordance with the key assumptions made at the design stage. The presented methodology could be helpful during production of non-conventional test surfaces.
