Here’s the technology you need for optimal cutting of a broad range of tubular materials and shapes. Article by Trumpf.
Because of their diverse shapes and materials, tubes and profiles can be used with great flexibility—from fitness equipment to furniture to agricultural machinery.
Conventional tube fabricators uses a variety of methods like sawing, lathe cutting, rotary cutting, supported shear cutting, and milling to cut tubes from long lengths into shorter pieces for variable parts and welded together for the final fabrication. No single method is optimal for cutting the broad range of tubular materials and shapes produced by this industry.
The most important areas of application:
The laser cutting of tubes offers you new tube design possibilities, which would not have been possible with conventional methods. Because of this, the following production steps are also reduced. Using the laser, you simplify welding fixtures and, therefore, lower the welding costs. Positioning aids with tabs and holes make component assembly easier and coding aids prevent assembly errors.
Advantages include product cost reduction, new product design, process simplification, lower organizational effort, shorter response times, simplification and optimization of parts, and reduction of downstream working steps.
Simple tube designs for connections reduce your work because the parts can be optimally cut for the subsequent joining processes, even without the bevel cut.
Advantages include optimal material utilization/saving, e.g. using the common cut; simplified joining; and less work, because of optimal cutting for the subsequent joining process.
Thanks to the high-quality bevel cut up to 45 deg, besides getting optimal material utilization and a reduction of work when cutting corner connections, you also get a greater part spectrum and aesthetic benefits in production and processing. Scribing of the material is often no longer necessary.

TRUMPF has developed a new programming software for laser tube cutting machines called “Programming Tube”. The software executes many work steps automatically, so that for many finished parts, no additional programming effort is required. The intuitive way of working ensures that users get used to the system quickly.
Programming Tube supports files in all common formats and enables the upload and construction of tubes and complete assemblies. When it comes to assemblies, the software programs bent connections at the touch of a button. These connections replace constructions that normally consist of several individual tubes. Connection and positioning aids between the tubes can also be implemented at the touch of a button. These aids help to simplify subsequent production steps, e.g. assembly or welding, prevent errors and save costs.
Programming Tube provides an extremely rapid method of programming tubes in 3D. Once the design process is complete, the software performs the programming process automatically. The software makes life easier for programmers by automatically determining how the laser tube cutting machine should eject parts and tap threads. Programming Tube creates the NC program from the thread parameters, including the necessary tools and the correct processing sequence. The way of working is intuitive. Instead of typing parameters into a dialogue field, they can now be adjusted directly on the 3D simulated part by simply using the mouse—which is less complicated. Users can also move the approach position of the laser with the help of the mouse. Additional modifications can be incorporated in the 3D simulation of the machining process if necessary.
