What Is the Difference Between 3-Axis and 4-Axis CNC Machining?

4 views

In 3-axis CNC machining, the tool moves along straight X, Y, and Z axes. In 4-axis machining, a rotary A-axis is added, allowing the workpiece to rotate. This enables the machining of complex features on multiple sides without re-fixturing.

Related to What Is the Difference Between 3-Axis and 4-Axis CNC Machining?

Although the hourly machine rate is slightly higher, 4-axis machining typically reduces total costs by minimizing the number of setups. For complex multi-sided parts, 4-axis machining is often more cost-effective than multiple 3-axis setups.

4-axis machining adds rotational capability, allowing features on multiple faces to be machined in a single setup. This reduces clamping time, improves accuracy between faces, and enables the production of cylindrical profiles and continuous spiral geometries.
