Abstract
This article explores the methodology of assessing the applicability of roughness parameters from the motif group to the evaluation of one-way and periodic geometrical surface structures. The results of surface roughness measurements of aluminum samples turned with variable kinematic parameters were presented. Usability of using surface motifs in combination with selected parameters described in ISO standards for assessment of geometrical structures characteristic for longitudinal turning was shown.
Highlights
In modern manufacturing techniques the main goal is to achieve good, repeatable quality of products
Characterizing surface roughness is currently taking a lot of significance in many areas related to the construction, technology and operation of machines and devices
Over the years, nearly 300 different roughness and waviness parameters were offered to the users [1]
Summary
In modern manufacturing techniques the main goal is to achieve good, repeatable quality of products. In case of the parts operating under specific conditions and determining the functional characteristics of the entire product e.g. the surface of the exhaust fins of internal combustion engines, two or more roughness parameters are used to assess the surface [4]. Another important aspect increasing the possibilities of describing surface geometrical conditions are differences in the standards regarding surface roughness used in individual countries. An example here can be the so - called French methods for roughness calculating They were created for the French automotive industry at the beginning of 80s of the last century.
