PRODUCT REVIEWS
At the EuroBLECH trade show in Hanover , TRUMPF is launching a new machine that automatically prepares components for welding . The TruLaser Series 3000 Bevel Cut Edition produces bevelled cutting edges ( chamfers ) on the top and bottom edge of the component while cutting . This is designed to ensure “ optimum preparation of the welding edges ” and saves an otherwise necessary downstream work step .
“ With the TruLaser Series 3000 Bevel Cut Edition , users get a particularly productive universal machine with which they are able to integrate downstream process steps into laser machining ,” said TRUMPF product manager , Patrick Schüle . The new TruLaser Series 3000 Bevel Cut Edition can apply chamfers to sheets of up to 25mm thick .
“ The machine can create chamfers of up to 50 degrees , depending upon the sheet thickness , which is more than the 45 degrees that were previously standard in the industry ,” explained Schüle . It can also handle complex bevel geometries . The solution is particularly suitable , said TRUMPF , for mild and stainless steel .
For 2D processing of components without bevels , users still have access to all TRUMPF laser-cutting functions such as Highspeed Eco for gas consumption reduction , FlexLine for the processing of different material grades and EdgeLine Bevel for rounding of the upper sheet edges .
Laser cutting and bevelling
The TruLaser Serie 3000 Bevel Cut Edition also produces complex bevel geometries and countersinks .
TRUMPF has equipped the cutting unit of the TruLaser Series 3000 Bevel Cut Edition with two additional rotary axes , particularly compact drive motors and a nozzle specially developed for bevel cutting . The cutting head can be tilted in all directions up to an angle of 50 degrees . The cutting unit regulates the distance to the sheet , minimizing the risk of collision despite the steep angle . The TruLaser Series 3000 Bevel Cut Edition is also equipped with TRUMPF collision protection .
“ Thanks to the high flexibility of the cutting unit , it is possible to create bevels in different geometries . In addition to the classic V and Y edges , edge geometries in which both sides of the component edge are provided with bevel cuts , DV and DY edges are also possible . This flexibility in the edge geometry is particularly

advantageous when complex components or groups of components are to be welded ,” continued TRUMPF .
To meet stringent demands placed on the preparation of complex bevel cuts , TRUMPF has developed a new , simple and intuitive programming system . It contains a preselection of all the processing strategies , which the user can adapt as required . There are also predefined cutting parameters for the special bevel cut nozzles .
“ This does not reduce the high productivity of the TruLaser Series 3000 ,” emphasised TRUMPF . It is launching this solution on its booth at EuroBLECH 2024 ( Hall 11 ). n

Simulation for significant output increase
With its new functions , Schuler ’ s ‘ DigiSim Unlmtd ’ software takes die simulation for transfer presses to a new level .
“ The simulation of the part flow in transfer presses offers many advantages . Because all motions relevant to freedom of movement , such as those of the slide and transfer , are included in the calculation , potential collisions can be identified in advance . As a result , the risk of failure is reduced and output increased by an average of 40 per cent . Our ‘ DigiSim ’ software can also be used to optimise die design . The latest version with the ‘ Unlmtd ’ addition is now suitable for forming systems from other manufacturers and offers a ‘ ViewOnly ’ function ,” stamping specialist , Schuler , told ISMR .
The freedom of movement simulation is also used to calculate the maximum stroke rates and setting data for the respective press . A collision check ensures the necessary safety distances between grippers and die .
“ This reduces downtimes and increases the overall system effectiveness because die , press and transfer are optimally coordinated ,”
explained Johannes Klein from Process Management at Schuler . The software can be used on all forming systems with two- and three-axis transfer systems .
Christof Kuchelmeister , from Schuler Process Management , explains how “ DigiSim ” helps with die design .
“ We receive initial information on the stroke rates during the part flow planning . This improves planning reliability during the quotation and project planning phase ,” he said . Movement curves and complete safety space ( the sweep volume ) of the grippers and components are also determined .
“ It ’ s almost impossible not to keep the necessary safety distance ,” he continued .
Tilting of components is also taken into account . Generated setting data can be transferred to the press , which speeds up the commissioning process . To ensure smooth communication between die design and production , the runable simulation files can be sent with the ‘ ViewOnly ’ software , which displays the clearance curves and allows measurements to be taken . This eliminates the need for time-consuming simulation reports .
“ In short , ‘ DigiSim Unlmtd ’ enables the design of higher quality dies at lower cost as well as shorter die commissioning with increased safety and increased output ,” summarised Klein and Kuchelmeister .
