Webinar - Roughness Parameters—How to Select the Most Meaningful One?

Information on surface roughness is usually captured with a single parameter, Ra. However, Ra only captures limited information on surface topography variations. The limited information from Ra forced engineers to define hundreds of additional roughness parameters that quantify characteristics such as period, shape, sharpness, volume, and predominant orientation. Faced with this multitude of parameters, it is difficult to determine which one is most meaningful to a specific application. Using examples from different industries, this presentation describes a consistent method to identify the most meaningful roughness parameter(s) for your application.
