<p><P>PROBLEM TO BE SOLVED: To provide a device for evaluating the finish condition of a metal surface, which is suitable for use at a production site. <P>SOLUTION: The surface finish determining device evaluates the finish condition of the machined surface of a workpiece ground and polished while being rotated. In the surface finish determining device, while rotating the workpiece, an image of the machined surface is taken by a line scan camera, and evaluation is made on whether or not the surface finish is fine by using a result of highlighting of a machining mark on the image taken by the camera or image processed through Fourier transformation or the like. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
