This VDA Recommendation deals with periodically occurring waviness in surfaces. It describes an evaluation method that identifies the periodic dominant surface characteristics and evaluates them using a WD waviness profile, from which parameters are subsequently derived. In particular, the division of wavelength ranges into a grid with graduated wavelength limit as suggested in DIN EN ISO 4288 is omitted in the determination of the waviness profile WD. The dominant waviness method thus ensures that periodic waviness is always correctly identified and evaluated. Experiences have been primarily made in the field of static and dynamic mating surfaces.
