Part 1:What Is 4-Axis CNC Machining?
4-axis CNC machining is an advanced manufacturing process that builds upon the capabilities of 3-axis machines by adding a rotational axis, typically designated as the A-axis (rotating around the X-axis) or B-axis (rotating around the Y-axis). This additional axis allows the workpiece or the cutting tool to rotate, enabling the creation of more complex geometries and features that would be impossible with 3-axis machining.
The X, Y, and Z axes represent the linear movements of the cutting tool, while the A-axis introduces rotational movement around the X-axis. This setup allows the machine to access multiple sides of a workpiece without manual repositioning, significantly reducing setup time and improving precision.
Comparison with 3-Axis and 5-Axis Machining
3-Axis Machining
