Contour Detection for Robotic Chamfering Based on Optical Measurement Technologies: Fringe Projection vs. Profile Sensor

In the present paper, two competing methods for contactless detection of component geometries are compared. In principle, it is important to examine the extent to which automation can succeed by mechanical machining processes by using advanced sensors. As an example of a process here the chamfering of large gearings with an industrial robot is chosen. It will examine to what extent there is a possibility to ensure through selected sensor applications and configurations, a geometry detection. Here ostensibly application-related parameters are presented and referred. This should also be done in regard to their use in industrial environments where metallic gloss and external light sources often present a problem. Finally, it should be a statement made as to whether the methods discussed are suitable for this application due to their technological parameters.
