An ultrasonic trimming device comprises an articulated robot, a cutter, and a grindstone. The cutter comprises an ultrasonic oscillator supported at the distal end of the articulated robot, a cutter blade supported by the ultrasonic oscillator, and a work securing portion for securing a work. The grindstone, i.e. an abrasive member arranged in the movable range of the cutter blade driven through the robot, is located at such a position as it can come into pressure contact with the cutter blade. The cutter blade is subjected to ultrasonic vibration by the ultrasonic oscillator under such a state as it is pressed against the grindstone by the articulated robot and polished. With such an arrangement, even a three-dimensional curved surface of a sheet material or a composite material composed of a soft material such as plastic, cloth or rubber or a material including glass fiber is cut efficiently by a method where the environment is taken into account.
L~invention concerne un dispositif d~ébarbage aux ultrasons, comprenant un robot articulé, un outil de coupe et une meule. L~outil de coupe comprend un oscillateur à ultrasons monté à l~extrémité distale du robot articulé, une lame de coupe soutenue par l~oscillateur à ultrasons et une partie de fixation de pièce à usiner servant à fixer une pièce à usiner. La meule, autrement dit un élément abrasif disposé dans la plage de mouvement de la lame de coupe entraînée à travers le robot, occupe une position lui permettant de venir au contact de la lame de coupe et d~exercer une pression sur celle-ci. L~oscillateur à ultrasons communique des vibrations ultrasonores à la lame de coupe de façon à la comprimer contre la meule et à la polir. Le dispositif de l~invention permet de découper efficacement une surface tridimensionnelle incurvée d~une matière en feuille ou d~une matière composite constituée d~une matière souple telle que du plastique, un tissu ou du caoutchouc, ou une matière telle que de la fibre de verre, au moyen d~un procédé respectueux de l~environnement.
