A Novel Laser Trepanning System for Research and Production
By: David Ashkenasi1, Tristan Kaszemeikat1, Norbert Mueller1, Reinhard Dietrich1, Daniel Jahns1,Gerd Illing1, Hans Joachim Eichler1,2 Tino Petsch3, Jens Hänel3, Christian Scholz3 To exploit the advantages of laser technology for material processing, e.g. micro drilling and cutting, versatile trepanning systems based on rotating optics have been designed and implemented. Depending on the development stage, the trepanning systems […]
Real-Time Process Control by Machine Vision
By: Christoph Franz Fraunhofer Institute for Laser Technology ILT, Aachen, Germany In recent years the use of modern solid-state lasers has brought about a distinct increase in operational speed in laser materials processing. Whether with scanners or fixed optics, high speeds – as far as possible in various axes at the same time – have […]
Laser-Based Repairing of Turbine Airfoils and its Economical and Environmental Impact
By J. Michael Wilson Purdue University Replacement costs for high value engineering components are very high due to long lead times and special tool required for processing high strength materials. Laser direct deposition provides an attractive and cost effective means for repairing or remanufacturing high value engineering components. Traditional repair processes are limited in applicability […]
