CNC Machining Design Guidelines
| Feature | Description |
| Internal corner fillets | Design internal corner fillets to be 0.020” - 0.050” greater than a standard drill size for the radii. Follow a drill diameter to depth ratio of 1:6 (1:4 recommended) as a guideline for internal corner radii. |
| Floor fillets | Design floor fillets smaller than corner fillets to allow the same tool to clear material from the interior. |
| Undercuts | Always design undercuts to standard sizes and away from corners so they are accessible by the cutting tool. |
| Tapped/threaded hole depth | Provide tool clearance slightly beyond the tapped hole depth to ensure complete threads. |
| Complexity | Keep the number of small cuts to a minimum to reduce CNC machining costs; only design in the necessary features to balance function with aesthetic. |
CNC Machining Tolerances
| 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 | Tolerances on metals will be held to +/- 0.005" (+/- 0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics and composites will be +/- 0.010”. |
| Precision Tolerances | FCE can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts. |
| Minimum Feature Size | 0.020” (0.50 mm). This may vary depending on part geometry and chosen material. |
| Threads and Tapped Holes | FCE can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review. |
| Edge Condition | Sharp edges are broken and deburred by default |
| Surface Finish | The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote. |
