Abstract
The disclosure reveals a computer vision technique to measure flank and crater wear of a single point cutting tool. This direct tool wear measurement method uses a microscope mounted camera to acquire an image of the tool. Special lighting of a face of the tool shows contrast of the wear region in the image. The image analysis is based on an interactive procedure utilizing a general purpose image processing system. A computer program calculates ten parameters to characterize flank and crater wear.
