  • Surface Texture Parameters
    Every part's surface is made up of texture and roughness which varies due to manufacturing techniques and the part structure itself. To understand a component's surface and to control the manufacturing process to the degree required in today's modern world, it is necessary to quantify the surface
  • Optical Instruments Defining the Evolution of Surface Texture Measurement in Manufacturing
    Surface texture measurement has a history that began a century ago with the advent of contact-type 2D measurement. Although measurement using optical instruments has been in existence almost as long as contact-type measurement, optical instrument measurement did not become widely used until about
  • Surface Analysis: Beyond Roughness
    and the reasons for doing so go far beyond roughness. In fact, many experts choose to use the terminology of "surface texture" rather than simply calling these characteristics "roughness.". Some measurements determine how a surface will bear loads, while others determine how well a surface provides
  • Measuring Surface Roughness and Texture
    We usually think of "smooth" as "slick" or "slippery." But did you know that a surface that is too smooth can actually be 'sticky'? Racing slicks on dragsters increase traction with the pavement, and a racing sailboat hull that is too smooth can actually increase drag through the water. In fact
  • Surface Finish: A Machinist`s tool. A Design Necessity
    Surface finish, or texture, can be viewed from two very different perspectives. From the machinist's point of view, texture is a result of the manufacturing process. By altering the process, the texture can be changed. From the part designer's point of view, surface finish is a condition
  • Texture and Microstructural Gradients in an Extruded Aluminium Profile (.pdf)
    recrystallized grain structure. The different positions through the thickness are denoted with different S values, starting with S=0.0 in the centre of the profile and ending up with S=1.0 at the profile surface, making it easy to separate the different positions through the thickness.
    Large area plastic screens are manufactured with different intricate patterns and surface textures on both sides in order to achieve the optical properties required for rear projection television systems.
  • Seeking a Smoother Way to Measure Roughness
    In seeking a way to measure surface texture, Brown found confocal technology from Olympus to be among the most versatile in terms of dealing with surfaces and roughness.
