What is 5-Axis CNC Machining?

Sage Metal Parts > Blog > What is 5-Axis CNC Machining?

A 5-axis CNC machining process is also a lot like a 3-axis CNC machining process. However, it comes with some very important features that provide those two extra axes and a great deal more cutting flexibility.

On a 5-axis CNC machining, the spindle and cutting tool moves along three axes. However, there are other rotations about the X-axis (called the A-axis), Y-axis (called the B-axis), and the Z-axis (called the C-axis). 5-axis machines can utilize any two of these rotational axes, depending on their configuration.

5-axis CNC machining is employed in different capacities based on this feature. It can perform milling, turning, etc. Therefore, you only need a single machine to work on several parts.

5-axis CNC machining is important in many scenarios related to product manufacturing. Based on the one you want, it is useful in creating molds with deep cavities, creating complex 3D shapes, and machining on tilted surfaces of a part without compromising precision. 5-axis CNC machining can be used for a wide variety of parts. For example, it has become particularly dominant in the production of parts like impellers and turbine blades, which have contoured surfaces unsuitable to 3-axis machining.
