Chamfer
A chamfer cuts an angled bevel along the top edge of a path using a V-bit. It runs as a single pass at the depth you set; the bevel width is determined by the tool's geometry, not entered separately.
Depth and width
You set the chamfer depth. The bevel width that results is
calculated from the V-bit's tip diameter d and included angle a:
chamferWidth = d + 2 * chamferDepth * tan(a / 2)
A wider chamfer needs either more depth or a flatter (larger-angle)
V-bit. To plan the other way around — pick a target width and solve
for depth — use chamferDepth = (chamferWidth - d) / (2 * tan(a / 2)).
Cut side
- Outside — the bevel is cut on the outside of the path. Useful for chamfering the top edge of a part you're cutting out of stock.
- Inside — the bevel is cut on the inside of the path. Useful for chamfering the rim of a pocket or a hole.
Settings
| Setting | Description |
|---|---|
| Chamfer Depth | Depth of the angled cut, in mm. |
| Chamfer Side | Outside or inside of the path. |
Feed rate, plunge rate, and spindle speed come from the assigned tool preset and don't need to be set per-operation.
Tool requirement
A tapered tool with a defined included angle (a V-bit). Flat endmills, ball endmills, and laser tools won't appear in the tool selector for chamfer operations.
When to use
- Decorative bevels on the top edge of a cut-out part
- Easing the rim of a pocket or pour-fill area
- Rounding sharp edges before assembly or finishing
