Laser deposition welding and milling in a single machine

01.12.2008
Improving the productivity of machining processes is one of the basic requirements in every machine-tool engineering specification. The Fraunhofer Institute for Material and Beam Technology IWS in Dresden has integrated a laser module into the tool station of a milling spindle.

The five-axis, computer-controlled milling center can now perform two jobs: Three-dimensional deposition welding using a 1.5-kilowatt diode laser and component finishing using 5-axis milling.

The IWS’s manufacturing experts will be exhibiting their two-in-one machining solution on the joint Fraunhofer stand at the EUROMOLD trade show in Frankfurt from December 3 to 6, 2008 (Hall 8, Stand L113).

»We linked all the processing steps on the basis of uniform CAD and NC data, and implemented them in a single machine with one tool fixture,« relates Dr.-Ing. Steffen Nowotny of the IWS in Dresden. The 5-axis CNC milling center is ideal for performing repairs on mold inserts used to manufacture plastic components, and for machining finely structured surfaces and functional coatings on metallic components.

Instead of having to discard damaged precision tools, they can now be returned to the workshop, reprocessed by the laser welding and milling machine, and reused – thus saving costs and reducing expenditure on new tools.

The combination of laser cladding and milling is also a cost-effective method of manufacturing complex molds and metallic components directly from the 3-D CAD model. The machining system’s high degree of automation and its multitasking capability are extremely useful attributes in applications such as aircraft engine maintenance and automobile construction: »The software links together all the individual processes. This simplifies and speeds up the task of programming the machine,« says Nowotny.

The use of a complete machining solution significantly improves process efficiency, because the numerical control system regards the laser tool head and the milling spindle as interchangeable tools. The ability to switch rapidly and easily between milling and laser welding provides added flexibility, resulting in a machine that offers all the necessary features for time-saving manufacturing processes.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
