so-called ‘tailored blank’ is formed into the final component reducing both the total cost and weight of the parts as well as the steel consumption and handling process. Tis process leads to optimised mechanical properties and, in the case of automobile parts, superior crash-test performance. (Image courtesy of ArcelorMittal) www.laserline.de

When less is more – pocket-size UV lasers for marking and micromachining


Jürgen Niederhofer, Newport Spectra- Physics


A new line of ultra-compact and powerful solid-state UV lasers with minimum thermal loads enable remarkably small, yet capable table-top instruments. Tis presentation outlines how pocket-sized UV lasers have surpassed much larger-sized UV lasers in a wide variety of micromachining applications ranging from marking to thin film patterning to additive manufacturing. Today, these tiny UV lasers deliver higher peak power and better mode quality, which results in smaller feature size and improved contrast, among others. In addition, feature-rich soſtware capabilities have specifically been designed for simplified product integration that help reduce time-to- market cycles for new developments. www.spectra-physics.com

Laser micromachining with multiple beams and tophat beam profiles


Christian Bischoff, Topag Lasertechnik


Te relatively high pulse energy and high output power of today’s lasers can oſten not be fully used in a laser micromachining process using a single beam. Diffractive beam splitters allow the generation of multiple beams helping to increase processing speed and save costs. Many laser micromachining processes like thin film ablation, require process optimised beam profiles. Top-hat or donut shaped beams can improve process quality and efficiency. Te so-called Focus Beam Shaping (FBS)

concept allows the generation of square or round shaped top-hat profiles with diffraction- limited spot sizes and high depth of focus comparable to a Gaussian beam. Te presentation demonstrates that the combination of beam shaping and beam splitting leads to higher process efficiency and improved ablation quality and showing scribing results of ITO thin film layers on glass with nanosecond and femtosecond lasers. www.topag.de

Investment, high-volume production – based on a dependent patent?


Dr Sebastian Tegethoff and Christian Fortmann, 24IP Law Group - Intellectual Property Attorneys


Investments in new products or production lines depend on several factors. One key factor is the question of whether a patent protects the new technology. It is quite oſten overlooked that a patented invention (‘dependent patent’) cannot be worked without exploiting an earlier patented invention (‘original patent’). Using a dependent patent without the consent of the owner of the original patent is associated with the risk of being sentenced to cease using the technology – besides the substantial costs related to patent infringement. Tis is the consequence of the basic principles of patent law, which by nature is a prohibition right. www.24ip.com

Robotics And Automation Showcase


Robotic marking in automotive production


Alastair Morris, Pryor Marking Technology


Pryor Marking Technology was recently


awarded an industry prize for innovation for the robotic laser marking solution it developed for a leading automotive manufacturer. Pryor systems installed in the UK and China are capable of laser marking the chassis in three locations, automatically locating the mark with vision systems and recording the quality of the mark, all within the 59-second cycle time. Furthermore, the same production line has multiple chassis


variations running along it with automatic programme selection. Te system gives the manufacturer improved traceability of chassis and eliminates quality rejections, benefits which translate to all manufacturing environments. www.pryormarking.com/news/214-lasys. html


Flange welding system with integrated seam tracking


Alexander Kranhold, Scansonic MI


Te ability to weld high volume sheet metal parts, as it is common in the automotive and rail industry or in


white goods production, is mostly ensured by applying flanges to both mating parts. Such flanges occur for example in door entries, window sections, pillars and in a vast variety of other parts. Tanks to an innovative ‘Flange Welding Head’, with integrated seam tracking,


clamping and full quality control, these flanges can now be reduced in height as the size of clamping tools or the geometry of spot resistance electrodes are no longer limitations. As a result, manufacturers can drastically save weight and hence reduce the carbon footprint of their products. www.scansonic.de/mittelstand

Laser Additive Manufacturing Showcase


Additive manufacturing: from prototype to series production


Jan-Peter Derrer, Renishaw


Renishaw is a global company with core skills in measurement, motion control, spectroscopy and precision


machining. Since the acquisition of MTT Technologies UK in 2011, Renishaw also focuses on its new business segment ‘additive manufacturing’. Renishaws ambition is the integration of this technology into existing
