Designing an Adjustable Mounting Tube in myPIPE — TubeCNC YouTube Channel
In “Designing an Adjustable Mounting Tube in myPIPE,” we walk through designing a practical mounting tube in myPIPE CAD/CAM — using circular mounting holes and elongated adjustment slots as cutouts positioned directly on the tube.
The result is a component that could be used for machine frames, equipment mounts, brackets, and other fabrication applications where an adjustable mounting point is useful.
What Happens in This Tutorial
- 1Open a tube part in myPIPE CAD3D and add cutouts from the part’s Cutouts list.
- 2Position each cutout along the tube using the Position X and Offset From Center fields, so it lands exactly where the mounting point is needed.
- 3Set up a circular mounting hole by entering its diameter and connection angle.
- 4Choose how the cutout is cut through the tube wall using the Contour Base (external, internal, or union) and Depth options.
- 5Add a second cutout shaped as an elongated adjustment slot alongside the round mounting holes.
- 6Review the finished tube, with its mounting holes and slot positioned on the part, directly in the 3D viewport.
What You’ll Learn
In this tutorial, we demonstrate:
- How to add and position cutouts on a tube in myPIPE CAD/CAM
- How to create circular mounting holes with a specific diameter and placement
- How to add elongated adjustment slots alongside round mounting holes
- How Position X and Offset From Center control exactly where a cutout lands on the tube
- How to preview the finished part in 3D before cutting
Why This Is Useful
Mounting points that combine a fixed round hole with an elongated slot give a part some built-in adjustability — useful whenever a bracket, mount, or frame member needs to be positioned slightly differently during assembly rather than requiring an exact fit.
Because the cutouts are positioned directly on the tube in CAD3D, the mounting geometry is designed and cut as part of the same tube profile — instead of being added as a separate drilling or slotting step after the tube is cut.
Using This in Real Tube-Cutting Workflows
This approach applies directly to parts like machine frames, equipment mounts, and brackets, where TubeCNC notes this type of component could be used. Designing the mounting holes and adjustment slots into the tube profile up front means the finished part comes off the machine ready to mount, without extra manual fabrication steps.
