Laser Technology: Bystronic’s Bystar Fiber Laser And Bytrans Loader

 

Bystronic – a world-leading provider of cutting and bending solutions – offers the steel industry the ultimate in productivity solutions.

By linking its flagship ByStar 10kW fiber laser to a ByTrans loader, it is now possible to automate production to a far greater level than was possible previously.

Bystronic’s 10kW ByStar Fiber laser, introduced at Euroblech in 2016, is to date Bystronic’s most powerful laser on the market. The ByStar Fiber’s new cutting head will deliver the highest part output through the full spectrum of sheet thicknesses, from thin gauge up to 30mm with an impressive part accuracy. It will also cut other exotic materials such as aluminium, brass and copper without the need for deburring. In terms of productivity, the ByStar Fiber is up to five times faster than a 4kW CO2 laser.

Even compared to a 6kW fiber laser, the time to complete a job on 6mm steel could be cut in half and the cost per part reduced by as much as 35%.

As the ByStar was designed from the ground up to be the most productive fiber laser on the market, it incorporates a number of other ground breaking design features. A newly developed ultra-fast bridge frame which is more torsionally rigid, gives greater accuracy and better edge quality. Bystronic’s detection eye technology identifies the edge of the sheet in six seconds, allowing cutting right up to the edge of the sheet with great accuracy. This significantly reduces a fabricator’s scrap rate.

However, the ByStar’s remarkable new levels of productivity could it be diluted if the loading and unloading of the machine are not able to match its superior production rate. To maximise the ByStar’s productivity potential, Bystronic therefore developed a range of loading and unloading automation solutions. Notable among these, the ByTrans Extended loaders are linked to the ByStar and will automatically load sheets onto the laser’s shuttle table. After the cutting cycle is completed, they are able to unload finished parts and residual sheets.

The ByTrans requires only 60 seconds in which to carry out the complete loading and unloading cycle. This means that the automation system is always faster than the cutting plan that is being processed. For fabricators or manufacturers, this means that the laser can cut uninterrupted for an extensive period of time. While the ByTrans loads one shuttle table, the fiber laser is cutting components from the raw material on an alternate table.

The ByTrans and the ByTrans Extended are operated using the ByVision touch screen. Bystronic has seamlessly integrated the control of the two automation systems into the laser’s operating software, which enables users to perform all the operating steps on a single touch screen.

The development of these automation technologies is part of Bystronic’s overarching aim to provide its customers with unsurpassed productivity solutions, ultimately leading to greater profitability.

Laser Technology: AMADA LCG-3015 AJ – Perfect Balance Of Low Energy Usage And High Speed Productivity

The new 9kW version of the AMADA LCG- 3015AJ Laser allows high speed and top quality laser cutting also of medium thickness materials, while providing a quality cut never previously achieved by a fiber laser.

Three 3-kW fiber laser modules form the basis for the 9kW version of the AMADA LCG-AJ laser cutting system.

The AMADA LCG-AJ completes the range of proven AMADA fiber laser systems for the high performance segment. The high output permits very high speed and top level quality processing of thin and midthickness materials. However, the system also supports the precise, reliable processing ofexceptionally thick sheets where the cutting speeds of mid thickness mild steel is 1 and 2 times faster than the 6kW. Furthermore, the high power fiber laser makes it possible to process various thick materials with quality results.

Latest generation of laser modules

AMADA was the world’s first laser manufacturer to develop its own fiber laser oscillator. In a CO2 laser oscillator, laser light is pumped with laser-gas, emitted via the output mirror and delivered by reflector mirrors to the cutting head. The fiber laser oscillator has no need for this. The monolithic structure allows the laser power produced by the individual laser diode banks to be combined into a single fiber optic cable for direct delivery to the cutting head.

In order to enhance the production of fiber laser oscillators at AMADA’s Fujinomiya facility and to meet ever increasing demand, clean rooms have been created specifically for production and assembly operations.

Alternative to the CO2 Laser

The AMADA LCG-3015AJ 9kW can be regarded as an appropriate, high performance alternative to CO2 lasers. It excels in terms of energy consumption: Although the output power has increased by a third compared to the 6kW laser, the energy consumption of the 9kW version is not significantly higher. By contrast, a similar increase in power in a CO2 laser would require significantly higher consumption levels. Another advantage: The AMADA fiber laser has a modular structure and its short wavelength means that there is no need for a deflecting mirror. Efficiency can be increased further through automation options such as the MPL (Sheet manipulator), the ASF (Sheet storage and manipulation) and even the TK system for individual part removal.

Machines are available in 2kW, 3kW, 4kW, 6kW and 9kW options.

Laser Technology: Platino Fiber Evo

Platino Fiber Evo is equipped with fiber laser sources (with 2, 3, 4, and 6 kW power) that provide the customer with high performance and, at the same time, great reliability.

One of the major innovations introduced is a new head for fiber laser cutting, which ensures significant benefits for the customer in terms of machine reliability, increased performance for reduced piercing times and increased cutting speeds, especially on thick material. Also, the new Platino Fiber Evo cabins increase the machine accessibility, reduce its overall dimensions and are easy to install. This version also features a new generation control, “Open”, produced by Prima Electro, that allows easy and complete management of the work programming and machine parameters.

In line with Prima Power tradition, the Platino Fiber Evo has been developed to maximize the customers’ competitiveness according to their applications. In fact, the machine is provided with different packages of options dedicated to the various production needs: Smart Cut, Max Cut and Night Cut.

New Head With Integrated Adaptive Collimator

The main innovation concerns the technological hub of laser machines, the cutting head. Platino Fiber Evo is equipped with the new cutting head with adaptive collimator designed and manufactured by Prima Power. It is a fiber laser cutting head with adaptive optics for automatic management of the focus position and focus radius diameter. Thanks to a quick, reactive and precise stand-off measurement, the new head is designed for excellent quality and dynamic cutting on all materials, but also for using maximum cutting pressures and resisting the most demanding environments. In line with Prima Power’s tradition, process reliability still provides important benefits thanks to the SIPS (Safe Impact Protection System), the lens case equipped with OPC (Optical Precision Control) quick alignment system and protection window case for easy inspection.

The head is equipped with a single focus lens, suitable for all production needs. The protection window is integrated into a dedicated case for easier inspection. The automatic adjustment of the focal position and the beam diameter provides excellent cutting flexibility of various thicknesses without manual intervention by the operator, ensuring maximum productivity.

The OPC (Optical Precision Control) can diagnose any differences between the real position and the theoretical position of the focusing beam and show them on the graphical user interface of the control system. Two knobs located at the front of the cutting head can be used to perform corrections that may be needed to center the lens in virtually no time.

A capacitive sensor keeps the distance between the nozzle and the sheet constant. The system is also equipped with a nozzle calibration and cleaning kit. After executing a predetermined number of holes or machined parts, the machine will automatically clean the nozzles and perform the sensor calibration cycle.

This translates to the customer in improved cutting performance, especially on thicker materials, reduced piercing times, and increased reliability of the entire machine.

New cabins

Another important new feature relates to the two new cabins available for Platino Fiber Evo, Lean and Open, which have been successfully introduced on the Laser Genius, another Prima Power 2D laser cutting machine. The Lean cabin is the best solution in terms of compactness, cost and easy installation.

With the Open cabin it is possible to utilize the good accessibility provided by cantilever structure of the machine. This cabin allows front, lateral and roof opening. The two lateral sliding doors can be completely opened to ensure excellent accessibility for the operator and allow easy loading and unloading of 1500 x 3000 mm sheets in any configuration, including automation. Next to the numerical control there is a manual opening sliding door that allows the operator to access the work area for lens replacement and routine maintenance operations.

New Open CNC Numerical Control

Platino Fiber Evo features the latest generation numeric control designed and manufactured by Prima Electro, a company of the Prima Industrie Group. It represents the intelligent and easy-to-use motor of Prima Power machines and provides the basic information to manage and monitor production. Its main functions include laser parameters monitoring and management, work programs editing and programming management with a complete preview function, also available in real time.

Dedicated Options For Every Production Need

The Smart Cut options suite is the ideal solution for fast processing of thin sheet metal (up to 6 mm thick) for which the nitrogen cutting technology can be used: a result obtained through technological solutions such as Smart Moves or Grid Cutting, which reduces unproductive times, such as the head positioning times. The result is a dramatic reduction in cycle times up to 30%.

To maximize productivity on parts made of medium and high thickness sheets (6 to 25 mm), the Max Cut options package was created. It is the integration of a customized database and of a series of technological options, achieved after many years of experience in the field of laser applications. It allows 40% cycle times reduction and a surprising 90% reduction of piercing time.

In case of intensive production, Prima Power has developed the Night Cut options package, which maximizes productivity and provides better process monitoring. This is made possible by devices that control the machining process status and intervene in case of errors restarting the operation or informing the operator remotely. The LPM (Laser Piercing Monitor) controls the piercing operations, the Plasma and TipTouch Restart monitor the cut, while the email Dispatching prompts the operator in case of problems.

Laser Technology: Unique Products Thanks To Laser Texturing

 

With the innovative LASERTEC Shape technology, DMG MORI has set new standards in the mould making sector.

The laser texturing of geometrically defined surface structures is more environmentally friendly than conventional etching and provides significant design freedom with at the same time highest reproducibility. Furthermore, the surface properties can be influenced in this procedure in a targeted way. Tool and mould makers benefit from this in almost all industries, where products also set themselves apart from the competition with individually designed surfaces: Fittings in the automotive industry, mobile phone cases, jewellery or drinks bottles. The LASERTEC Shape series from DMG MORI provides suitable production solutions. With the LASERTEC 45 Shape, the LASERTEC 75 Shape as well as the large models LASERTEC 125 Shape and LASERTEC 210 Shape, the machine tool manufacturer covers practically all component sizes.

With the innovative LASERTEC Shape technology, DMG Mori has set new standards in the mould making sector – representation of a glove compartment cover with combined honeycomb/leather structure.

The introduction of the LASERTEC Shape technology was a big step for tool and mould makers. Particularly in automotive engineering, there has since been a futureoriented alternative to conventional etching. Other industries benefit from the significantly higher precision compared to conventional milling. Blow moulds for PET bottles, or for example watch faces in the watch-making industry can be equipped with finest structures, but also lettering and engravings.

LASERTEC 75 Shape – state-of-the-art laser and future-oriented software

DMG MORI is prepared for this development and has only recently integrated the compact LASERTEC 75 Shape in its portfolio for laser texturing, which is already fully equipped for Industrie 4.0. With a footprint of < 8 mÇ, it is the ideal complement even in tightest production environments. Its ergonomic design with a door opening of 1,310mm provides perfect access to the generously dimensioned work area. Workpieces weighing up to 600kg (with the optional tandem drive up to 1,000kg) with diameters of max. ø 840mm and heights of 520mm find sufficient space here. The traverse paths are 750mm x 650mm x 560mm in the X, Y and Z axes.

The core elements of the LASERTEC 75 Shape are the powerfully pulsed 100 W fibre laser and the 3D processing optics. These are responsible for the material removal by 3D laser in layers and in combination with the NC swivel rotary table, provide contourparallel laser shaping. This enables fast and smooth laser texturing also for 3D free-forms.

When it comes to the control system, DMG MORI relies on a SIEMENS 840 D solutionline for the LASERTEC 75 Shape. Combined with CELOS, the machine can also be optimally integrated into the company organization. User-friendly and applicationrelated LASERSOFT software features ensure simple and productive operation of the LASERTEC 75 Shape.

Laser Technology: TRUMPF – Laser Welding Saves Time And Money

One of TRUMPF’s goals at the Schweißen und Schneiden welding trade fair in Düsseldorf was to demonstrate how lasers can facilitate the welding process.

“Laser welding may not be able to replace every MAG weld seam, but it offers plenty of advantages in the cases where it can,” says Thomas Rupp, Head of Sheet Metal Laser Welding at TRUMPF. The ongoing trend towards greater product customization poses a challenge to companies as they seek ways to produce small batches more efficiently. Cost per part is a key factor – and one way to reduce it is by minimizing throughput time. Joining is one of the steps that offers particular potential in this regard. Depending on the quality requirements in each case, parts often require several minutes of finishing work to grind down beads on conventional weld seams. That’s where laser welding can make a real difference: whatever the batch size, a laser can reduce the need for post-processing and accelerate the joining process. Investments in this technology quickly pay for themselves, even with small batch sizes. “In many cases you can cut costs by 50 percent or more,” says Rupp.

Less finishing work required

Deciding which laser welding method is the most economical choice depends on the type of part you are processing. Heat conduction welding joins together thin-walled parts and produces seams of very high surface quality. In many cases, this eliminates the need for any subsequent grinding and polishing of the joint, which is why this method is particularly suitable for parts that need an aesthetically superior finish. Another advantage of heat conduction welding is its low heat input, which means that less heat enters the part during machining. This reduces deformation and cuts the cost of subsequent straightening. Overall, this method requires considerably less post-processing, which significantly reduces the cost per part. In the case of a hood made from mild steel 1.5 millimeters thick, for example, the use of a laser has been shown to reduce machining time by 90 percent for a weld seam 122 centimeters long.

Fast welding, new opportunities

Deep penetration welding produces deep, narrow, high-strength weld seams. It can be used with both thin and thick-walled metal sheets, and it gets the job done fast. For example, the 600 centimeters of seams  required to weld together a water tank made from stainless steel three millimeters thick can be handled by a laser at welding speeds of up to 5.4 meters a minute. At that rate, it takes less than 2.5 minutes to weld together the entire tank. Processing times as short as these drive down part costs. What’s more, lasers enable users to open up new avenues of business. This flexible tool can handle a multitude of new joint types and geometries, even if the area to be welded is only accessible from one side. Examples of the challenges lasers can tackle include lap seams, concealed T-joints and even materials of different thicknesses.

Welding together a hood made from mild steel 1.5 millimeters thick using a laser has been shown to reduce machining time by 90 percent for a weld seam that is 122 centimeters long.

Heat conduction and deep penetration methods offer the best quality when it comes to laser welding, though to achieve this the part should normally be subject to the tightest possible tolerance levels. The new FusionLine joining technique can be used to join parts, even when this involves the bridging of gaps. It smooths out any unevenness during the welding process and closes gaps up to one millimeter wide. That makes it possible to use the laser on many parts that were originally designed for conventional welding methods. As a result, FusionLine provides an easy introduction to the world of laser welding, enabling users to boost the capacity of their machines. The system can easily switch between FusionLine and other laser welding methods without retooling, even when it is halfway through processing a part.

Thanks to deep penetration welding, the 600 centimeters of weld seams required to produce a water tank can be processed in less than 2.5 minutes.

The plug-and-play integration of the TruLaser Weld 5000

The TruLaser Weld 5000 machine is designed for sheet metal manufacturers who are keen to enter the realm of laser welding. This automated laser welding system can handle heat conduction welding, deep penetration welding and the FusionLine process. The system offers a range of loading and unloading solutions, including the possibility to load the next parts while welding is still taking place. The TRUMPF LaserNetwork system gives sheet metal manufacturers an economical way to gain a foothold in this new technology. It allows the welding machine to use a beam source from an existing machine, eliminating the price of the laser from the investment in the new system.

Autonomous 3D Scanner Supports Individual Manufacturing Processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part.

But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time.

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or stops working in the vehicle, however, this special status quickly becomes a problem, as spare parts are no longer manufactured either. With the advent of Industrie 4.0, this is set to change: manufacturing is turning toward batch sizes of one and individualized production. This is sometimes also referred to as highly customized mass production.

New scanner works autonomously and in real time

Although this kind of individual manufacturing is still some way off, researchers at the Fraunhofer Institute for Computer Graphics Research IGD are taking the vision of batch sizes of one a big step closer to reality, with a new type of 3D scanning system. “The special thing about our system is that it scans components autonomously and in real time,” says Pedro Santos, department head at Fraunhofer IGD. For the owners of vintage cars with a broken part, this means that the defective component is glued together and placed on a turntable, which is situated beneath a robot arm with the scanner. Everything else happens automatically. The robot arm moves the scanner around the component so that it can register the complete geometry with the minimum number of passes. Depending on the size and complexity of the component, this takes anything from a few seconds to a few minutes. Already while the scan is running, intelligent algorithms create a three-dimensional image of the object in the background. Then a material simulation of the 3D image checks whether a 3D print satisfies the relevant stability requirements. In a final step, the component is printed using a 3D printer and is then ready to be fitted in the vintage car.

No need for protracted learning process

Santos emphasizes that the real achievement here is not so much the scanner itself, but the combination of the scanner with view planning to form an autonomous system. This view planning technology was also created by Fraunhofer IGD. During an initial scan, algorithms calculate what further scans are necessary so that the object can be recorded with as few scans as possible. Thanks to this method, the system is able to quickly and independently measure objects that are entirely unknown to it. This is a unique selling point, because previous scanners either had to be taught how to do this, or else you had to have the CAD model of the component, making it possible to recognize the position of the object relative to the scanner. If you had taught the scanner to scan a car seat for quality control (TARGETACTUAL comparison), then it would be able to scan the next 200 car seats, because they would be largely identical in mass production conditions. But conventional scanners are not suited to the task of handling batch sizes of one. “By contrast, our scan system is able to measure any component, irrespective of its design – and you don’t have to teach it,” explains Santos. “Also, you don’t need information about CAD models or templates – in other words, the specifications of standard forms that a component usually has.”

Manufacturing assistant for Industrie 4.0

Thanks to this USP, the autonomous scanner enables completely new kinds of applications. For example, it can be used as a manufacturing assistant and improve cooperation between humans and machines. This interaction is the focus of the EU-funded Autoware project, which involves the assembly of cylinders including the various pistons, casings and seals. Before now, the cylinders were assembled manually and the subsequent quality control was carried out using a printed checklist and manual measurements. “Our 3D scanning system now enables robots —via comparisons with the database — to recognize what component it has in front of it and also to determine which component its human colleague needs next for assembly of the cylinder,” explains Santos. In addition, the machine carries out the final quality control, scanning the cylinder to check whether the dimensions are accurate. As part of further projects, the Fraunhofer IGD researchers are also testing the entire chain from recording and visualizing up to 3D reproduction.

The researchers will be presenting their autonomous scanning system at Hannover Messe Preview on February 6 and at Hannover Messe from April 23 to 27. Visitors will get the opportunity to place various objects under the laser scanner and view the results live on a monitor. Upon request, they can also scan their own objects. This will allow them to see for themselves how the system actually captures the precise geometry of three-dimensional objects autonomously and in real time.

Efficient Use Of Resources In Manufacture Of Metal Components

Additive Manufacturing has established itself in many industrial sectors as a method for making plastic parts.

The 3D printing of metals is on the road to becoming a similar success story. In the newly opened 3D-Printing Lab for Metals and Structural Materials at the Fraunhofer Institute for High- Speed Dynamics, Ernst-Mach-Institut, EMI, researchers have investigated how resource-efficient the manufacturing process is when lightweight aluminium components are manufactured using additive methods. They discovered that even marginal reductions in the material and resources used per component yield high cost savings in series manufacturing.

The 3D-Printing Lab for Metals and Structural Materials at Fraunhofer EMI in Freiburg houses one of the largest commercially available 3D printers for metal currently in existence. In the research sector, an apparatus of this size is unique. Using the selective laser melting technique metal structures with dimensions of up to 40 centimeters can be made by additive manufacturing. 3D printing offers completely new ways of designing components with highly complex shapes and optimizing their weight. But it is only by combining Additive Manufacturing and intelligent lightweight design that you can maximize resource efficiency in manufacturing. Fraunhofer researchers in the 3D-Printing Lab have investigated just how economical the manufacturing process is in terms of resources and whether material and operating costs can be minimized compared to conventional industrial methods. To do this, they took a practical, widespread component for their tests: a wheel carrier such as might be used in a lightweight vehicle. “We were able to quantify the effect lightweight construction – and specifically the use of structural optimization methods – has on the resources used in the SLM manufacturing process,” says Klaus Hoschke, scientist and group leader at Fraunhofer EMI. The focus was on energy and material consumption, the manufacturing time and the CO2 emissions that arise during the small-scale production of twelve wheel bearings.

Resource efficiency of a small manufacturing run

After the researchers had used the numerical finite element method (FEM) to simulate and analyze a draft design and determine the right geometric shape with structural optimization methods, they constructed the wheel bearing in an optimized lightweight design.

The result was a wheel bearing designed for the defined load scenarios and offering maximum performance. Because of their geometric complexity, structures produced in this way cannot be manufactured by conventional methods such as milling or turning. “With the lighter model, we were able to save hugely on resources during production, as less material has to be produced per component. If you multiply this by the number of units in a small-scale run, then you require less time, material and energy for manufacturing. Reducing volume through the use of higher-strength materials offers the greatest potential for energy savings here,” says the researcher. Using the numerically optimized version of the wheel bearing, 15 percent less energy was required for the additive process than for the conventional method: Twelve kilowatt hours of electricity were needed for the conventional design, whereas only ten kilowatt hours were needed for the numerically optimized design. (In each case, the measured value refers to a series-manufactured component.) Manufacturing time was cut by 14 percent and CO2 emissions by 19 percent. And where material consumption was concerned, it could be significantly reduced by 28 percent.

Additive Manufacturing – the method of choice

Although structure-optimizing algorithms and numerical optimization simulations are already being employed in the 3D printing of components today, they are only used when the component must be extremely lightweight, such as aircraft parts designed to reduce fuel consumption during operation. Components that lack these implications as regards structural optimization are still generally manufactured using conventional industrial methods. The results of the smallscale series production of the wheel bearing suggest that additive manufacturing can also be useful when a component does not have to be structurally optimized as such. “A heat exchanger or a tool mold, for example, do not have to be lightweight to improve their functionality. Nevertheless, it makes sense to design them with reduced weight and volume when manufacturing them additively, because this way you can bring down manufacturing costs,” explains Hoschke.

Forecasts on what effect the Additive Manufacturing of metals will have on global production vary widely. But everyone agrees on one thing: for many industries – such as aerospace, automotive engineering, medical engineering and toolmaking – it is a game changer. “Our positive results for resource efficiency in the manufacturing process should reinforce this,” says the scientist. In the future, Hoschke and his team want to research the extent to which other design heights, series sizes and materials such as titanium affect the resource efficiency of the manufacturing process.
