What Are The Different Parameters Used To Quantify Surface Roughness?

Ra (Average Roughness)

Ra represents the arithmetic average of the absolute values of the surface deviations from the mean line within the sampling length. It provides an overall measure of the roughness of the surface.

Rz (Mean Peak-to-Valley Height)

Rz measures the average distance between the highest peak and the lowest valley within the sampling length. It offers insights into the differences in elevation across the surface.

Rq (Root Mean Square Roughness)

Rq calculates the root mean square of the surface deviations from the mean line within the sampling length. It provides a measure of the average height deviations from the mean line and is useful for evaluating the fine details of the surface texture.

How Does A Surface Roughness Tester Measure Surface Roughness?

Surface Roughness Tester

A Surface Roughness Tester typically uses a stylus or probe to measure surface roughness. The stylus is moved across the surface, and as it encounters irregularities, it generates electrical signals. These signals are converted into numerical values that represent the height variations of the surface. The tester’s probe may have a diamond or a ruby tip, which allows it to accurately trace the surface profile. The stylus is guided by a motorized or manual mechanism, and the displacement of the stylus is recorded and analyzed to determine various surface roughness parameters. The measurements are then displayed on the tester’s screen or can be recorded digitally for further analysis.
