摘 要：
To ensure tool wear measurements to be completed within a specified period of time, this paper presented a measuring method for different tool wear parameters. The system had the characteristics of flexible measurement, high precision and high spatial resolution. The tool wear measurement system consisted of a light source irradiation tool, a CCD camera, a laser diode(for contour depth assessment), a linear projector, a snapper and a PC. The feature of this technique was to determine the contour depth by projecting the laser grating line on the tool surface. Using the method proposed in this paper, 3D images could be obtained without using a very complex measurement system. Compared with other techniques that could measure two-dimensional contour, it had obvious advantages.
