Understanding 5-Axis CNC Machining
What is 5-Axis CNC Machining?
5-axis CNC machining refers to the capability of a CNC machine to move a cutting tool or workpiece along five distinct axes simultaneously. This advanced technology enables the production of intricate parts with high accuracy. Unlike traditional 3-axis machines, which operate only along the X, Y, and Z axes, 5-axis machines introduce two additional rotational axes—commonly referred to as A and B axes.
How 5-Axis Machining Works
5-axis machining operates by utilizing a combination of linear and rotary movements. The cutting tool can approach the workpiece from virtually any angle, allowing for complex machining operations. This flexibility reduces the need for repositioning the workpiece, minimizing errors and enhancing efficiency.
