Changes Ahead in the Roughness Standards
I have written numerous articles on tooth flank surface roughness measurement. This is such a page-turner of a subject!...
View MoreMaterials Matter : Roughness Measurement: Optical vs. Contact Stylus Profilometry
Optical profilometry will become an important tool for predicting gear performance with more research and development of an objective lens to fit into tooth spaces....
View MoreMaterials Matter : Roughness Measurement Tips: Calibration, the Razor Blade Test
If a problem is found with a contact stylus profilometer during routine check with a Rubert-Song specimen, do a little troubleshooting before sending it off for calibration and recertification....
View MoreA Comparison of Surface Roughness Measurement Methods for Gear Tooth Working Surfaces
Surface roughness is a critical parameter for gears operating under a variety of conditions. It directly influences friction and contact temperature, and therefore has an impact on various failure modes such as macropitting, micropitting and scuffing...
View MoreVibratory Media Compositions vs. Attrition and Density
The third in our multi-part series on vibratory processing of gears is focused on understanding how media of different compositions have varying attrition rates and densities, and why these are important in vibratory finishing of gears. ...

View MoreISF Surface Versus Machined Surface
Why ISF® Surfaces are superior to machined surfaced: As the load of the mating surface is increased, the lubrication film becomes thinner, and the asperities of the machine surface contact each other resulting in plastic deformation, metal debris an...
