Getting the Most Out of Tube Profile Laser Cut

Tube, pipe and profile laser cutting offers fabricators greater flexibility than flat sheet metal laser cutters when it comes to design and production.tube profile laser cut The machines can handle a variety of shapes, sizes, and thicknesses. But getting the most out of these machines requires a thoughtful approach to the material and design.

A few key considerations can make the difference between an excellent result and a frustrating one.tube profile laser cut

For starters, the kerf that's created by the concentrated beam during cutting needs to be accounted for in the design file.tube profile laser cut This seemingly minor detail becomes critical when pieces have to fit together precisely.

To avoid oversized gaps, fabricators can minimize wasted material by designing tabs, slots, and joints that interlock with mating parts. This can simplify assembly and, in some cases, eliminate secondary processes. For example, a tab positioned to align with a slot on a matching part can allow the two to be welded together without the need for complex welding jigs.

Another important factor is to consider the tolerances that are associated with the stock material. For instance, when cutting stainless steel or titanium, stock tolerances are often looser than they are with carbon steel. That's why it's best to avoid dimensioning features from the outside edges of the stock and instead reference them from the centerline, as shown in the image below.

In addition, laser cutters require the part to be normalized to the surface on which it will be cut. The reason is that lubricants used in upstream cutting and forming operations can remain on the surface of a tube or pipe, so they must be removed before the machine cuts it. In some cases, these contaminants can interfere with the laser's ability to produce sharp and accurate cuts, especially with thicker-walled materials.

A final point to keep in mind is that tube-cutting machines typically operate at lower speeds than flat laser cutters. This is because they have to accommodate a shorter working length. That means that the parts need to be loaded and unloaded more quickly. In addition, the machines need to take more frequent measurements to ensure that they are performing properly.

While there are solutions for these issues, fabricators should be aware of them when preparing their designs and materials for laser-cutting. By addressing these and other factors, fabricators can achieve the best results from their tube and pipe laser cutting.

The backbone of commercial and industrial buildings, 'I' or 'H' beams distribute weight evenly to support massive structures. They are manufactured from a variety of alloys, including carbon steel, stainless steel, and aluminum. For each, there are specific grades that meet commercial standards set by organizations like the American Society of Testing and Materials, the American Iron and Steel Institute, and the Society of Automotive Engineers. For fabricators, ensuring that their design files accurately reflect the properties of these alloys can improve production efficiency and yield better quality. To help maximize the benefits of their tube and pipe laser cutting, Top Tubes recommends that they use a 3D model with STEP as an output format. This will allow their systems to more effectively account for the kerf, which is particularly important when cutting nonround tubing.
