Materials Processing

Ultrafast Material Processing with High‐Brightness Fiber Lasers

Machine tool builders demand cost reductions in many material laser processing applications like additive manufacturing, thin film ablation, surface structuring, cleaning, and foil cutting. All markets lead laser and optoelectronic component suppliers in the same way to improve the throughput as well as yield of available laser power. A feasible way of achieving cost reductions is to use existing machine components and...

Surface Processing

EHLA: Extreme High‐Speed Laser Material Deposition

Special coatings protect components against corrosion and wear. However, standard processes such as hard chrome plating, thermal spraying, laser material deposition or other deposition welding techniques have drawbacks. For example, as of September 2017, chromium(VI) coatings will require authorization. Researchers from the Fraunhofer Institute for Laser Technology ILT in Aachen as well as the RWTH Aachen University have...

Laser Cutting

Processing of Highly Reflective Materials

Fiber lasers have become more accepted for industrial laser applications all around the world. For many years, companies and universities have developed new generations of fiber lasers which compete with other laser types such as CO2 lasers. As the market for CO2 lasers shrinks, the solid‐state laser market expands due to advantages such as higher efficiency, high beam quality and the ability to process highly reflective material such...

The Incredible Additive Manufacturing Creates Movement

At a first glance, additive manufacturing seems to be a very simple manufacturing process. Nevertheless, many companies are not happy with their adaption of this new technology or are even overburdened by it. Often, we have to undisputedly agree with these companies. However, we can change their opinions straight away. The fascinating metal 3D printing nowadays even manages to print moving objects without needing assembly...

Laser Welding

Advances of OCT Technology for Laser Beam Processing

Optical coherence tomography (OCT) is an innovative sensor 3D measuring system for automated laser processing, in particular laser welding. It facilitates laser beam positioning, process monitoring, and quality control with the required precision and guarantees process flexibility, stability, and trace‐ability. To ensure smooth seam tracking for time‐ and cost‐effective line production, Lessmüller Lasertechnik OCT systems...

Next Generation of Jigless Robot Welding

Technicians around the globe are preoccupied with the concept of fully automatic, just‐in‐time welding of different components down to a batch size of 1 in unattended operation without time‐consuming set‐up. For an Austrian global market leader in formwork solutions this vision has already become lived reality.

Application Report

Generative Complete Machining in Finished‐Part Quality

Hoedtke GmbH & Co. KG has been regarded as innovation‐oriented service provider in the field of chipping and chipless metal processing. Since December 2014, the company has been threading another new path in production with a Lasertec 65 3D from DMG Mori: With the laser deposition welding and 5‐axis simultaneous machining, the machine combines additive and subtractive manufacturing processes, thus offering entirely new...

High Accuracy Laser Processing with a Rotating Beam

Ultrashort pulse lasers have been industrially available for a few years, and are increasingly being used in everyday production. They are very well suited for micro machining since they can be focused to an extremely small tool size, and due to contactless and athermal operation. But to compete with conventional production methods such as EDM, milling, punching, honing or grinding in micro‐drilling, cutting and turning,...

Efficient Machine Vision

Volkswagen in Emden, with over 264,000 vehicles produced and 9,700 employees on an area of 4,100,000 m2 (status 12/2015 source: Volkswagen), is the largest industrial employer to the west of Bremen and to the north of the Ruhr area. The 50th anniversary of the existence of the location was celebrated in 2014. The focus at the location is the production of the Passat B8. According to VW, with the current Passat, the...
