Improving applied roughness measurement of involute helical gears

“…The roughness profile measurements were taken prior to and after each sequential test regime. The measurements were taken following a repeatable well-defined gear roughness measurement method published previously [6]. The application of this method has demonstrated its ability to detect sub-micron surface texture changes on a gear flank, despite acknowledging that further improvements to the form removal method are possible.…”

“…The measurement uncertainty of this shop floor machine was assessed following the guidelines in the references [8,9]. The gear is located in reference to the profiler axis with a fixture, which is illustrated in Figure 1 and described in detail in the reference [6]. The fixture provides a rigid mounting which can be replicated closely at each measurement interval.…”

“…A new approach to roughness measurement recommends a more robust definition of the gear roughness measurement method, described in [6], that better represents the functional (meshing action) of the gears during operation. The method allows repeatable measurements to be made on a gear flank from root to tip.…”

A Novel Measurement Standard for Surface Roughness on Involute Gears

“…There still is a gap in dimensional metrology between measurement technologies for inspecting surface textures and for inspecting 3D geometries [10,11]. Surface texture measurement strategies consider a surface as a plane with the topographic features perpendicular to the plane and being around three orders of magnitude smaller than the lateral sizes.…”
