Abstract
This paper presents a high speed and a high accurate measurement method for the height of the cutting edge of a rotary cutting tool with respect to the reference surface on the tool by using a laser displacement sensor. In this method, the height of the cutting edge is obtained from the output of the optical displacement sensor when the intensity output reaches the maximum. Both simulation and experimental results confirmed that the proposed method enables us to measure the height of cutting edge, the width of which is smaller than that of the laser spot.
