Traceable roughness measurements on complex-shaped surfaces are a challenging task due to the spatial distortion of the profile or area to be measured. A novel type of traceable roughness standard for involute gears is therefore being developed at PTB. This material measure is designed for both use in modern gear measuring systems and for standardized roughness measurements. In this study, a multi-step process chain is presented to manufacture such line profiles on curved surfaces in hardened steel and carbide. It is based on a novel semi-deterministic grinding process, using a 5-axis ultra-precision machining centre. The desired roughness profile is calculated with the knowledge of the topography of a ground trace. A computer program superposes and assembles partial profiles.
The geometrical information of the completed artificial profile is then converted into an executable program for the machining process. The experiments show that the predictability and repeatability of the grinding process are sufficient to achieve the desired roughness values. In one of the first steps, the novel semi-deterministic grinding process is validated in-plane.
