What is CNC Machining?
CNC, or computer numerical control machining, is a widely used manufacturing process that uses automated, high-speed cutting tools to form designs from metal or plastic stock. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers.
Skilled machinists operate CNC machines by programming tool paths based on the geometry of the final machined parts. The part geometry information is provided by a CAD (computer-aided design) model. CNC machines can cut almost any metal alloy and rigid plastic with high precision and repeatability.
Artemis 3D provides CNC services and offers custom CNC quotes on over 50 materials ranging from commodity aluminum and acetal to advanced titanium and engineered plastics like PEEK and Teflon.

CNC Machining Tolerances
Precision machining with tight tolerances for demanding applications
| Feature | Description |
|---|---|
| Maximum Part Size | Milled parts up to 80" x 48" x 24" (2,032 x 1,219 x 610 mm). Lathe parts up to 62" (1,575 mm) length and 32" (813 mm) diameter. |
| Standard Lead Time | 3 business days |
| General Tolerances | Metals: +/- 0.005" (+/- 0.127 mm) per ISO 2768. Plastics and composites: +/- 0.010". |
| Precision Tolerances | Sub +/- 0.001" tolerances available per drawing specifications and GD&T callouts. |
| Minimum Feature Size | 0.020" (0.50 mm). May vary depending on part geometry and material. |

CNC Machining Design Guidelines
Optimize your designs for manufacturability and cost
| Feature | Guideline |
|---|---|
| Internal Corner Fillets | Design to be 0.020" - 0.050" greater than standard drill size. Follow 1:6 depth ratio (1:4 recommended). |
| Floor Fillets | Design smaller than corner fillets to allow same tool to clear material. |
| Undercuts | Always design to standard sizes and away from corners for tool accessibility. |
| Threaded Hole Depth | Provide tool clearance slightly beyond tapped depth for complete threads. |
| Complexity | Minimize small cuts to reduce cost. Balance function with aesthetics. |
