Key points of CNC design

1、Cavities and pockets: Recommended cavity depth: 4 times cavity width. End mill tools have a limited cutting length (typically 3–4 times their diameter). Deep cavity milling: Cavities with depths greater than six times the tool diameter are considered deep. A tool diameter-to-cavity depth ratio of up to 30:1 is possible using specialized tooling (maximum depth: 35 cm with a 1-inch diameter end mill tool).

2、Internal edges: Vertical corner radius,Recommended: ⅓ times cavity depth (or larger). Using the recommended value for internal corner radii ensures that a suitable diameter tool can be used and aligns with guidelines for the recommended cavity depth. Floor radius,Recommended: 0.5  mm, 1  mm or no radius.

3、Thin-wall: Minimum wall thickness, recommended: 0.8 mm (metals), 1.5 mm (plastics)

Feasible: 0.5 mm (metals), 1.0 mm (plastics).

4、Holes: Diameter, recommended: standard drill bit,Feasible: any diameter larger than 1 mm. Maximum depth, recommended: 4 times nominal diameter,typical: 10 times nominal diameter, Feasible: 40 times nominal diameter.

5、Threads：Thread size，minimum: M1 (and lower, in some cases)，recommended: M6 or larger. Thread length,Minimum: 1.5 times nominal diameter, recommended: 3 times nominal diameter.

6、Tolerances：Typical: +-0.1 mm，Feasible: +-0.02 mm.
