CNC Machining Design Guidelines
Optimize your designs for manufacturability with our comprehensive guidelines. Our engineering experts provide detailed feedback on your custom machined parts to ensure optimal CNC machining results.
| Radii | In CNC machining, sharp internal corners on a workpiece will naturally form rounded corners (radii). The depth must not exceed 12 times the diameter of the drill. For end mills, the depth must not exceed 10 times the diameter of the tool. |
| Threads and Tapped Holes | Diameter Φ 1.5-5 mm, depth: 3 times the diameter. Diameter Φ 5 mm or larger, depth: 4-6 times the diameter. Seaforest can produce threads of any specification and size as required by the customer. |
| Undercuts | Square profiles, full radius, dovetail profiles. |
| Text | CNC Milling: Minimum width of 0.5 mm and depth of 0.1 mm. CNC Turning: Seaforest can use laser marking to create standard text for CNC turned parts. Seaforest can create standard text via CNC engraving or laser engraving as per customer requirements. |
