In a set made of tubing, repeating holes and preparing joints can occupy a considerable part of the work. Laser tube cutting allows for the execution of geometries that are part of these connections, provided that the design and equipment capacity are adequate for the request.

For those preparing a structure or component, the advantage begins with the possibility of thinking of the tube as a piece ready for the next phase. This requires defining the openings, the orientation of the faces, and how each element fits into the assembly.

Start with the section and wall thickness.

Indicate whether the tube is round, square, rectangular, or of another profile. Include the external dimension, wall thickness, material, and length. When there is a specification from the supplier or project, send that document as well.

The advertised sheet metal cutting capabilities should not be used to draw conclusions about the tube. The section, length, and geometry of the work need to be confirmed with the workshop.

Holes on different faces need a common reference.

In a square tube, a hole on the wrong face can render the component unusable even if the diameter is correct. Show the orientation of the part in the assembly and identify the faces consistently in the drawing.

Define where the positions are measured from. If several elements need to align with each other, highlight this relationship. Photographs of an existing assembly can help, but they do not replace the elevations needed for manufacturing.

Tube junctions deserve to be drawn.

Cutouts at the ends can prepare connections between parts and aid in positioning. TRUMPF documentation on tubular part design. presents examples of connections and positioning aids designed for this process.

The specific application must be evaluated as a whole. A fitting that facilitates assembly does not eliminate the need for dimensioning the connection, welding, or fasteners. In structures with technical requirements, share the design and acceptance criteria.

Identifying parts facilitates delivery to assembly.

When there are similar tubes, assign a reference to each element. Include a list with the quantities and an assembly view. Ask that the proposal clarify how the parts will be grouped or identified upon delivery.

If the work includes several revisions, confirm which is the final version. This discipline is especially useful in a series where a small change affects only a few components.

What to prepare to request laser cutting of a tube.

Send the drawing of the part and the assembly, material, section, thickness, lengths, and quantities. Mark the critical areas and explain what will be done after cutting. If you need bending, welding, or finishing, include these steps.

Lumiinox offers sheet and tube cutting in its workshop services. Share the drawings for analysis and confirm the capabilities applicable to your profile before closing the order. You can also consult general information about laser cutting.
