    What is Surface Roughness | Roughness Measurement Working Principle

    Friday, October 4, 2019 |

    In many applications, surface roughness is closely allied to function, for instance where two surfaces are in close moving contact with each other their surface roughness will affect their sealing or wear properties. This might suggest that it is a case of "the smoother the better", but this is not always true as other factors may be involved. Where lubrication is involved it has been found that roughness valleys are required to hold oil. Also, the financial aspect must be considered: it costs a lot of money to produce very smooth surfaces and the expense of this exercise can add to the bill considerably without gaining a great deal of performance.

    The automotive sector is comprised of numerous complex engineering processes that must operate to outstanding levels of precision in order for the finished product to meet consumer standards and professional certifications. In recent decades, auto engineering has moved towards pervasive automation with robotic assembly lines. However, analysing the surface composition of mechanical components for contours and variations widely remains a manual process.

    What are Roughness and Contour Measurements?

    Contours refer to the nominal form of a surface, excluding irregularities that could be categorized as roughness or waviness. Characterizing the contours of a surface profile is complex as it can be inherently difficult to separate waviness from general form.

    Form, roughness, and topography are most commonly measured using contact metrology instruments, which acquire surface profiles by moving a sensitive stylus across the measured component in a pre-defined direction. A diamond tip with micrometre (μm) dimensions acquires variations in resistance to applied pressure, but this is typically limited to variations across a single plane.

    Surface profilers are used to measure and characterize the surface features of material on the micro-and nanoscale. These minute topographical features are typically categorized as roughness, waviness, or directional lay, representing potentially microscopic structure superimposed on the true form of a material’s substrate.
