CNC Milling (3-axis)

Capability bounds and precision manufacturing specifications for CNC Milling (3-axis).

Capability Bounds

CNC Milling (3-axis) capability specifications
Standard ToleranceTypically ±0.1 mm for the first 25 mm, plus ±0.002 mm for each additional mm. Tighter tolerances are achievable but significantly increase tooling and processing costs.
Min Feature SizeMinimum Draft Angle: 0.5° on highly polished surfaces (SPI-A1/A2); 1-2° is standard for most features; 3°+ for textured surfaces (e.g., VDI 3400).
