Optical measurement of groove geometry

Abstract Feature recognition and measurement in manufactured parts can be used for correcting tool paths, deciding suitable process parameters and verifying the quality of a completed production step. In this study, V-groove with root face in a butt joint between two steel parts with machined bevels are measured using a commercial optical triangulating sensor consisting of a laser source and a digital camera. This feature is difficult to measure due to reflections off the machined sides of the groove. This study demonstrates top gap, root gap and groove depth measurement, as well as tack weld detection.
