<p>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.</p> |
