| Zusammenfassung | The quality inspection of involute gears is still a vital step within contemporary manufacturing processes. High demands on the performance of gearboxes define the requirements that are placed on the applied measurement techniques. Current challenges in manufacturing metrology as derived from trends in production technology can be summarised in five keywords: fast, accurate, reliable, flexible, and holistic. Modern coordinate metrology systems can gather holistic information about the dimensions and surface of complex-shaped workpieces with high point density in short time scales and on a decent accuracy level. However, standardised evaluation procedures still refer to single lines representing the gear geometry in the most relevant 2D-sections. This has been state of the art for many decades and may be sufficient for quality control as long as the production method follows the kinematic principle of mating gears and manufacturing tolerances aren’t too tight. However, holistic evaluation procedures considering the complete gear surface in one common model have several advantages. Besides obvious benefits, that deviations along the whole flanks can be determined and geometrical fitting parameters are more stable and sounder, holistic treatment allows to find correlations between different gear measurands and to properly understand possible manufacturing errors. Moreover, modern production methods that do not follow the generative principle like five-axis milling need holistic gear inspection for reliable quality assurance. This contribution proposes a novel 3D evaluation strategy for cylindrical involute developed at the Physikalisch-Technische Bundeanstalt (PTB) in Germany. We will introduce the topic with a historical overview of previous works (Lotze, Sourlier, Pfeifer, Goch) and work out the main aspects considered in our own approach. The work is currently being implemented into a national guideline by the VDI/VDE FA 3.61 |
