New Feature (V-Groove Cut) Added to Our myPIPE CAD/CAM — TubeCNC YouTube Channel
Published August 25, 2026 · TubeCNC Blog · Software Update
TubeCNC has posted a short preview on YouTube, “New feature (V-Groove cut) added to our myPIPE CAD/CAM,” showing a new V-groove cut option for tube parts in the CAD/CAM software.
The clip is a quick, close-up look rather than a full walkthrough, so this article focuses on what the V-groove cut option is and what it’s for, based on what’s shown on screen.
A V-Groove Cut Option for Tube Joints
- 1Start with a tube part modeled in the CAD/CAM software, alongside its mating fitting.
- 2Open the new V-groove cut option and set it up using its parameter panel.
- 3Apply the cut, which shows as a V-shaped notch cut partway through the tube wall.
- 4View the tube split into two segments at the notch, showing the V-shaped joint clearly.
- 5Fold the two segments together at the V-groove so they meet at an angle, forming a mitered joint.
- 6Carry the finished part through to the myCNC controller, where the cutting toolpath is simulated on the tube.
What You’ll Learn
From this preview, here’s what the V-groove cut option covers:
- Where the V-groove cut option lives in the tube CAD/CAM workflow
- How a V-groove cut is applied to a tube as a V-shaped notch
- How the notch allows two tube segments to fold together at an angle
- How the resulting joint looks once the segments are brought together
- How the V-groove cut carries through to a cutting toolpath in the myCNC controller
Why This Is Useful
Joining two tube segments at an angle — for a corner, elbow, or angled frame member — usually means cutting a precise notch so the pieces meet cleanly before welding. Working that cut profile out by hand for every angle is slow and easy to get wrong.
A dedicated V-groove cut option gives a more direct way to define that notch in the CAD/CAM software and see the resulting joint before it’s cut.
Using This in Real Tube-Cutting Workflows
V-groove joints come up anywhere tube segments need to meet at an angle rather than run straight through — structural frames, angled brackets, and corner or elbow joints in a weldment are common examples. Being able to define the notch on the tube itself, and check the resulting angle in the 3D view, can make that joint more repeatable across a production run compared with working it out manually for each part.
