What Is the Cost Difference Between 3-Axis and 5-Axis CNC Milling for the Same Part?
Core Cost Differences
For the same part, 5-axis CNC milling typically costs 1.5 to 3 times more per hour than 3-axis milling, due to advanced equipment, higher programming complexity, and operator skill requirements. However, this hourly rate difference can be offset by fewer setups, better accuracy, and reduced overall machining time for complex geometries.
Feature | 3-Axis CNC | 5-Axis CNC |
|---|---|---|
Hourly Rate (typical) | $40–$70 | $100–$200 |
Setup Complexity | Simple | Advanced (multi-face access, fewer setups) |
Machining Time for Complex Parts | Longer (requires multiple setups) | Shorter (machined in one setup) |
Precision and Geometry Access | Limited | Excellent (simultaneous multi-axis positioning) |
Best For | Flat or prismatic parts | Complex 3D surfaces, undercuts, turbine parts |
When 5-Axis Is More Cost-Effective
While the base hourly rate is higher, 5-axis machining reduces total cost in many cases by eliminating multiple setups, improving geometric accuracy, and reducing fixture costs. For example:
A part with features on five faces may take 3 setups in 3-axis, but only 1 setup in 5-axis.
Critical tolerances involving angular features or curved surfaces are easier to maintain in one clamping.
Aerospace, medical, and automotive industries benefit significantly from the precision and efficiency of 5-axis CNC.
Example Scenario
A complex aluminum bracket requiring contouring and hole drilling on three faces:
3-Axis Cost: $300 (3 setups × $60/hr × ~1.7 hours + inspection)
5-Axis Cost: $250 (1 setup × $140/hr × ~1.5 hours, tighter tolerances, less rework)
Even though the hourly rate is higher, 5-axis results in lower total cost for complex parts due to reduced handling and machining time.
