Design Guidelines for CNC Machining
Optimize your designs for manufacturability using our expert guidelines. Our team offers valuable feedback on your custom machined parts to ensure the best results in CNC machining.
| Description | |
| 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. Arapidtools can produce threads of any specification and size as required by the customer. |
