Abstract
A 3-D tool wear analysis method has been developed to measure erosive wear parameters such as area and volume automatically and objectively. Parallel light stripes are projected onto a wear area at a known angle. Knowledge about the light pattern is utilized in processing the digitized image data to compute local depth. The new method was successfully applied to sub- optimal images where magnification is necessary, such as cutting tool wear. Since this is a general image processing problem with a structured light source, this method can be easily adapted to other applications.
