In the invention, an ultrasonic processing apparatus (4) is moved along a planned groove process line and along the side of a rear face (3b) of a resin skin (3) which is fixedly held so that the front face is closely in contact with a flat face (1a) of a surface table (1), so that a resin for the skin is sequentially fused by ultrasonic vibration to process a wide linear groove (6). An image of a residual portion (6d) of a bottom portion of the linear groove (6) is taken in one direction on the groove opening side by using a laser displacement sensor and CCD camera 10, and the image is processed. The thickness of the residual portion (6b) is measured and recorded so as to be effectively used as a feedback material for processing the linear groove (6) with high reproducibility.
Selon l'invention, un appareil d'usinage ultrasonore (4) est déplacé, le long d'une ligne de formation de rainure préétablie, sur la surface arrière (3b) d'un revêtement en résine (3) dont la surface frontale est solidement contrecollée à la surface plate (1a) d'un marbre (1) pour faire fondre progressivement le revêtement en résine par vibrations ultrasonores et former une large rainure linéaire (6). Une partie résiduelle (6b) au fond de la rainure linéaire (6) est photographiée d'une direction du côté de l'ouverture de la rainure au moyen d'un capteur de déplacement laser et d'une caméra CCD (10), et l'image est traitée aux fins de mesurer et d'enregistrer l'épaisseur de paroi de la partie résiduelle (6b), ce qui donne un matériel de réaction permettant de former la rainure linéaire (6) avec une bonne capacité de reproduction.
