Speeds and Feeds
Speeds and Feeds
Start conservative. Increase feed only after successful test cuts. Match RPM to material and bit diameter.
1.5kW spindle limit: Avoid bits larger than ~1.5" diameter — excess mass can fault the VFD.
Starter Values (Not Yet Shop-Verified)
Values below are placeholders derived from manufacturer guidance and Vectric defaults. They will be replaced after test cuts at the makerspace.
| Material | Bit type | Diameter | RPM | Feed (IPM) | Depth/cut | Notes |
|---|---|---|---|---|---|---|
| Hardwood | Up-cut end mill | 1/4" | TBD | TBD | TBD | From manual — verify at shop |
| Plywood | Up-cut end mill | 1/4" | TBD | TBD | TBD | From manual — verify at shop |
| MDF | Up-cut end mill | 1/4" | TBD | TBD | TBD | From manual — verify at shop |
| Plastic | Up-cut end mill | 1/4" | TBD | TBD | TBD | From manual — verify at shop |
TBD: Shop-verified speeds and feeds after test cuts. Rows will be tagged "shop-verified" when confirmed.
General Guidance
- Always confirm units (IPM vs mm/min) match your G-code post-processor
- Use VCarve's tool database as a starting point, then verify on scrap material
- Reduce depth per pass if you hear chattering or see poor chip evacuation
- Refer to bit manufacturer recommendations for your specific cutter
