TRUMPF will be highlighting its laser expertise at Lasys 2014

Added to MTDCNC by TRUMPF on 19 May 2014

In its exhibit at the Lasys 2014 trade show in Stuttgart, TRUMPF will be demonstrating its competence as a partner to manufacturers of laser systems. Beginning with beam source and guidance, continuing to optics and sensors – even including software, everything needed is available from a single source. Not only does that save time and money. It also ensures trouble-free interplay of all the components involved – making for perfect results.

The Power of Choice: Broadening the extensive product portfolio

In Stuttgart, TRUMPF will be highlighting its expertise in questions of integration with two world premieres – the TruMark 5010 and the new generation of diode lasers built around the TruDiode 4506. The TruMark 5010, based on the fiber laser, has been designed as an “all-in-one” solution for marking. It brings together – in a single housing – the fiber laser, the scanner, the controls and an internal focal position control. No separate supply unit is required. Its space-saving design, the high availability of the interfaces, and the efficient air cooling system predestine the TruMark 5010 for integration into production systems. The same holds true for the new TruDiode 4506. With its small footprint, compact construction, and modular design makes it easy integrating the unit into existing manufacturing lines. The new generation of direct diode lasers delivers excellent seam quality in both heat conduction welding and deep welding and offers high repeatability of the results. This generation is distinguished by its good efficiency level, at up to 40 percent, and includes ideal lasers for energy-efficient industrial manufacturing in multi-shift operations.

Everything on hand for successful integration

No matter whether beam source, beam guidance, optics or sensors are needed – the TRUMPF technology portfolio offers a wealth of accessories optimized to match the existing process. All components – including the controls, interfaces, and software – are perfectly matched one to another and can, in every respect, satisfy the highest demands. That makes TRUMPF laser technology superbly prepared for integration into larger systems. Laser applications are many and varied and every application involves its own very special requirements. What beam source can be combined with which optical equipment to create the best configuration for a specific need? With its broad spectrum of technology and decades of experience, TRUMPF offers consulting and solutions for virtually every application.

A basic prerequisite: Expertise in interfaces and software

The interfaces are decisive to successful integration of a laser into a machine or a manufacturing line. Solid-state lasers by TRUMPF are very flexible in such situations since they are compatible with all the field bus systems commonly found in industry. The clear advantage here is that the user profits from a uniform control architecture. TruControl software represents the hub of the entire laser system. This software is what the operator uses to write laser control programs, to and archive parameters, and to optimize processes. The software also makes possible remote services, records data relevant to quality, and monitors threshold values.

Using flexible beam guidance to achieve goals

The laser beam makes its way from its source to the workpiece either through free beam guidances or laser light cables. With its own solutions and components, TRUMPF is able to set up ideal, flexible systems. At the Lasys 2014, the company will be showing a number of beam guidances and switches that can divert the laser beam to any of a number of workstations. The details of the application will determine whether the laser power is split again at the workstations or is available alternately through certain periods of time. Especially fast beam switches take only 30 milliseconds to divert the beam, making the system significantly more efficient, economical and profitable. In addition to the time-tested laser light cables for a variety of beam qualities, fiber profiles are available, matched to special requirements. Examples are the rectangular and square fibers needed to process large surface areas. A very special design is the TRUMPF 2-in-1 laser light cable. Here the user, with just a single cable, can switch between two different core diameters. This will result in two different focal diameters, so that the user can both cut and weld at a single station, without having to change out the laser light cable.

The right optics make the laser work
 
The laser beam actually become a useful tool only after the appropriate optical elements have been added. Those optics shape and focus the beam and deliver supplementary substances like the gas required for cutting or welding. No matter whether static or scanner designs are required: TRUMPF develops high-performance, superbly flexible optics for a wide variety of applications. With the introduction of the second generation of programmable focusing optics (PFO), the company is underscoring at this year’s Lasys its leading position in both classical laser remote processing and on-the-fly machining. In addition to improved dynamics and precision, innovative functions distinguish the new optical systems. Thus it is possible, for example, to measure the mirror position exactly and to correct it, if needed – regardless of the prevailing temperature and humidity. In this context, TRUMPF will be demonstrating the new PFO SmartTeach App at the LASYS. With this app the user can set up the PFO program directly at the workpiece, with all the convenience of the tablet computer, by way of live image transmission. This brings about considerable time savings.

Keeping an eye on all the processes
 
Camera-based solutions are a proven medium in process monitoring. TRUMPF offers several cameras and sensors for welding and cutting with solid-state lasers. They can readily be integrated into the optics, so as to observe the process. The same cameras can also be used for the so-called offline position control. Should workpieces be misaligned, this will be recognized by the image processing software, which corrects the laser control program accordingly. The feature recognition function even makes it possible to align the welded seam along circular openings or edges. In addition, the image processing system can read out and store quality data. The seamless integration of the image processing at the laser control interfaces gives rise to a finely tuned solution which can easily be integrated into existing systems. In laser marking, too, and thanks to the Observer camera system specific to the TruMark, a variety of functions is made available. It is possible to detect the position of the workpiece and to correct the marking procedure accordingly – and to read barcodes and automatically set the focal position.
