Martin Stein has studied mathematics and physics at Leibniz University Hanover, Germany, and finished his Ph.D. in 2012. He’s been heading the working group for gear and thread metrology at Physikalisch-Technische Bundesanstalt (PTB) since 2014. One of that group’s main research areas is metrology for large gears as used in wind energy systems. Martin Stein is an active member in national standardization bodies for gear metrology of the VDI/VDE and DIN. He is a lecturer at TU Braunschweig for the MSc course on Metrology and Measurement Technology.
As well as evaluation of profile, helix and pitch deviations, harmonic analysis of measured 2D trace data is routinely used by some industries to control gear noise and characterize machine tool performance. Evaluation of 3D surface measurement data has not been investigated.
