KEYENCE's Introduction to "Roughness" website introduces parameters and case studies related to such surface measurements. - Roughness is measured in a trasversal direction to the main grooves. - The mean arithmetical value “Ra” in μm is assumed for roughness measurements. -Rt: maximum value of roughness from the lowest to the highest point. -Rz: average roug hness in 10 p oints. SURFACE ROUGHNESS CONVERSION CHART Surface finish Ra and Rz roughness specification -upmold. Surface finish, also known as surface texture or surface topography, which is produced in every manufacturing process, refers to the nature of a surface of a part, defined by characteristics of lay, surface roughness and waviness.
