Surface roughness - Wikipedia
网页The basic symbol of surface roughness. Digital holographic microscope measuring hip prosthesis roughness. Surface roughness can be regarded as the quality of a surface of not being smooth and it is hence linked to human (haptic) perception of the surface texture.
Ra, Rz, Rmax, Rz1max, Maximum Height - Michigan Metrology
网页This article discusses several key surface texture measurement parameters: average roughness (Ra), average maximum surface height (Rz), maximum of all per-sampling-length peak-to-valley heights (RMax), and the Maximum Height (Rz1max). We discuss the sensitivity to extreme peak/valley structures of these surface roughness parameters, as …

Maximum Height Of Profile (Rz, Pz, Wz) - KEYENCE America
网页The maximum height of the profile indicates the absolute vertical distance between the maximum profile peak height and the maximum profile valley depth along the sampling length. When dealing with roughness profile, Rz is referred to as the maximum roughness, while Wz is referred to as the maximum waviness when dealing with waviness profile.
Surface finish Ra and Rz roughness specification -upmold
网页Learn about surface finish Ra and Rz roughness specification, how to measure and compare them, and how they affect the quality of plastic injection molded parts.
网页Rz (μm) Application example In a periodic profile the mean width of the profile elements RSm is used. With an RSm between 0.4 and 1.3 mm the following measuring conditions result: λc = 2.5 mm / ln = 12.5 mm / lt = 15 mm / r. tip. = 5 μm / λs = 8 μm.
