Most CNC Users Don’t Know This Fence Trick

Описание: If you’ve ever struggled to accurately position odd-shaped parts in your CNC, this trick will save you hours.

In this video, we walk through how to design custom fences directly inside your CAD/CAM software so your parts locate perfectly every time inside your CNC vertical workstation.

This technique was used in our Bar Stool Project where we needed to machine precise joinery on curved components that were originally cut flat.

By creating a custom MDF fence based on the exact shape of the part, we can guarantee:

✔ Perfect alignment
✔ Repeatable setups
✔ Accurate joinery
✔ Faster machining workflows

You'll also learn how to:

Rotate parts accurately in CAD

Use your original part geometry to design fixtures

Add cutter clearance for internal corners

Match hole patterns to CNC vertical plates

Create clamp clearance pockets

This simple workflow dramatically expands what you can do with your CNC machine.
