es, the scientists and their colleagues at Alzmetall have developed a machine with which they are able to work on the free-form die inserts and forging dies. The scientists have also developed a software with ModuleWorks that ensures that the laser travels across the surface at a constant speed and that the gaps between the laser paths remain even otherwise tears would develop in the surface. "This isn't a problem if the surfaces are straight; however, we had to develop special algorithms for free-formed tools that keep the path distance and the speed constant even with complex geometries," said Arntz. The machine and the software are ready; the scientists have already manufactured initial tools and dies for the industry. They will introduce the technology at the Euromold trade fair (Hall 11, Booth C66) from November 27 - 30 in Frankfurt, Germany.

The scientists are planning, in a further step, to reduce expensive raw materials such as chromium, molybdenum and vanadium. To date, these materials are present in all forging dies. "We want to utilize the basic fundamentals of our technology so that we only have to alloy the reworked surface layer with these materials."
