This webinar focuses on the practical impacts and differences between stylus and areal methods of assessing mean roughness (Ra), as well as the key considerations necessary for determining the most appropriate applications for either method.
Stylus-based profilers have long been used to capture mean roughness (Ra) and to assess product and process quality. However, modern engineering and manufacturing often generate random and/or complex engineered surface textures that are difficult to assess with a single-line profile.
Consequently, though mean roughness can easily be captured through one—or a few—profiles for standard manufacturing processes (those which leave a single texture orientation), optical areal measurement becomes mandatory to properly evaluate the surface in many cases.
This webinar aims to provide both theoretical background and practical measurement considerations (including filter selection, measurement setup, and data processing) for measuring profile and real mean roughness using Bruker's Stylus and Optical profilometry solutions, highlighting the ways that both profile and areal methods are able to co-exist in modern industry.
