<P>PROBLEM TO BE SOLVED: To provide a contour shape measuring method and a contour shape measuring device in which a contour shape of a measuring object such as a processing tool used for a machine tool can be measured accurately from a change in the quantity of light of a light beam detected by a photodetector by scanning a contour of the measuring object with the light beam. <P>SOLUTION: In a measuring device, regarding light emitted from a light source 20, a measuring object (such as a tool) and its contour T are inserted within a beam range B of the light. While moving the measuring object and its contour T or the beam of light in X and Z directions, based on a change in the quantity of light obtained by detecting the quantity of laser light through a photodetector 21, the measuring object and its contour T are measured/evaluated accurately. <P>COPYRIGHT: (C)2013,JPO&INPIT |
