Case Studies

Again, based upon agreements with customers no details can be disclosed. Basically it is a system with a six-axis robot. The laser beam is delivered by means of a flexible optical fiber. In its wrist the robot carries a cutting optics with a capacitive height sensor. This ensures that the essential parameter "nozzle stand off" which is crucial for the quality, is kept constant. The movements of the robot is in accordance with the required cutting contour. The absolute accuracies are 0.15 mm which is sufficient in BIW applications. There is a range of solutions for robot applications available which feed the media to the robot hand; therefore the use of lasers and optical fibers represent no problems.
