For many years, the focus of the design of precision components for transmissions has been on optimizing gear geometry. The work in this area has come so far that we are now seeing a shift from design to a concentration on surface quality of the functional surfaces. The roughness of highly stressed gear flanks has significant influences on noise, wear, and power loss. Thanks to new or improved machining technologies, extremely smooth surfaces can now be produced cost-effectively. The need now arises for reliable measurement of roughness of gears. This paper discusses the newest solution that enables fully automatic measurements of gear geometry and roughness in one clamping.
