It seems like only yesterday when, while attending a German fabrication machinery show, we were introduced to multikilowatt fiber laser sheet metal cutting. If I recall, this system exhibitor had a large sign stating the effect of what high-power fiber cutting can do and a video display showing nested, 3-in.-diameter holes in 6 mm mild steel being cut at almost blinding speed. At the time, I remember questioning how potential users were going to handle the large quantities of cut pieces and skeleton scrap, not to mention the continuous feeding of new sheets, all to match the very rapid cutting rates (time has clouded my memory on the exact speed of cut).
Over the succeeding years, fiber laser power quickly ramped up and today, 10 kW units are common and the ever-faster cut part, scrap, and sheet feed problem has also led to more and better process automation. Kinney Manufacturing, described in one of our features this month, has enjoyed the benefits of today’s high power high-speed laser cutting systems, theirs from Bystronic. Randy Kinney, company president, sums it up noting that process equipment automation allows them to pass on savings to customers and, better yet, to reinvest in additional automated solutions (see article).
Frequent Industrial Laser Solutions contributor Geoff Shannon (Coherent) states that over the years, laser technology has enabled product innovation and typical 5%+ annual growth in medical device processing, and is paying off for laser vendors. He selects welding, marking, cutting, and micromachining as driving laser technology growth. This doesn’t come free, as there is growing interest in systems that run and control the process, support hardware, and process data and analytics, providing automation, a “smartphone”-like software user interface, and ultimately more cost-effective solutions (see article). Perhaps you have noted the theme, process automation, in this month’s issue.
In the June issue, we will turn our interest to the industrial lasers market in India, as well as how laser powder-bed fusion systems are dominating the laser additive manufacturing landscape.
