Carveco Tutorial: Creating Chamfers and Grooves

In this tutorial, you'll learn how to use profile toolpaths in Carveco to create both chamfers and decorative grooves. These finishing touches can add detail, depth, and polish to your machined projects using V-bits, ball nose tools, or other form tools.

🔹 Creating a Chamfered Edge

Turn on your vectors and select the outer edge of your shape.
Go to Toolpaths > Profile Toolpath.
Set the path to follow Along the vector rather than Outside/Inside.
Enter a Finish Depth (e.g. 0.1") depending on how deep you want the chamfer.
Select a 90° V-bit to achieve a 45° chamfer.
Click Calculate and then Simulate the toolpath.

🔹 Adjusting Chamfer Depth

If the chamfer is too shallow, double-click the toolpath and increase the finish depth (e.g., from 0.05" to 0.1").
Recalculate and re-simulate to view the updated result.

🔹 Creating Grooves Along Vectors

Select inner vector paths where grooves are needed.
Create a Profile Toolpath set to follow Along the vector.
Use a small Finish Depth like 0.04".
Select any V-bit or form tool based on the shape of groove you want.
Click Calculate and simulate the toolpath.

🔹 Using Other Tools for Grooves

You can experiment with tools like a Ball Nose, Round-Over, or even a flat End Mill.
Choose based on the profile you want to carve and simulate to preview it accurately.

✔️ Key Takeaways

Use Along vector profile paths for chamfers and grooves.
90° V-bits produce classic 45° chamfers when used with symmetrical depth.
Grooves can be cut with any form tool, not just V-bits.
Adjust finish depth to control width and depth of cuts.
Always simulate toolpaths to preview results before machining.

🔧 Advanced Techniques

Use trigonometry to calculate exact chamfer width and depth when using custom angled tools.
Combine chamfers and grooves in layered toolpaths for ornate signage or decorative inlays.
Create custom groove paths using curves or imported vector artwork.

🛠️ Troubleshooting

Problem: Chamfer doesn’t appear deep enough.
Solution: Increase the finish depth and re-calculate.
Problem: Grooves appear uneven.
Solution: Check tool size and ensure toolpath follows Along the vector.
Problem: Toolpath cuts outside your model.
Solution: Confirm path type is set to “Along” the vector, not “Outside” or “Inside.”
