New System Tracks Contours During Laser Materials Processing

Facebook Twitter LinkedIn Email Comments
AACHEN, Germany, May 16, 2011 — Fraunhofer Institute for Laser Technology has developed a process monitoring system that can precisely measure the position and speed of a laser beam processing point on a surface. The tracking system minimizes deviations from desired contour and speed and helps stabilize energy input. A novel system developed in Germany allows precise measurement of the position and speed of a laser beam processing point on a work surface. In this image, the measured feed rate and trajectory in a welding process are shown. (Images: Fraunhofer Institute for Laser Technology ILT) In recent years, the...Read full article
