This paper introduces the widthmeasurement of a cutting tool edge by utilizing a laser triangulation displacement sensor. By using the reflected light intensity of the laser displacement sensor, micrometric edge width which is smaller than the diameter of the laser beam spot can be measured. With regard to the quantitative evaluation of the laser spot diameter, a calibration method of the laser spot diameter is achieved by using the pin-gauges. The diameter of the laser spot is obtained by using the pin-gauges, and the relationship between the reflected light intensity and the diameter of the pin-gauges are investigated. The width of the cutting tool edge is measured by the calibrated laser spot diameter, and then the reproducibility is evaluated.
