    results in deviations from the desired surface patterns. A number of standard parameters are used to describe surface roughness of engineered surfaces. Average roughness (R a) is the average of the individual heights (asperities) and depths from the arithmetic mean elevation of the profile. 1 1 0 0 1 (, ) m n a k l k l R Z x y mn µ ...

    Roughness affects various part characteristics, including the amount of wear, the ability to form a seal when the part makes contact with something, and the ability to coat the part. KEYENCE's Introduction to "Roughness" website introduces parameters and case studies related to such surface measurements.

  • Surface Profile Gauge

    The Elcometer 122 Testex Replica Tape is a very simple technique to measure a surface profile. The foam side of the Testex Tape is used to mould the peak-to-valley profile of the surface and then the measurement is taken by the Elcometer 124, a mechanical Surface Profile and Thickness Gauge.
