CNC Wood Router With Rotary Axis

CNC machining is the process of removing material from a workpiece until the desired shape is configured. These machines have at least a 3 axes and operate along an XYZ plane: X axis (vertical), Y axis (horizontal), and a Z axis (depth).As the name implies, they operate on three axes: the X-axis, which moves left-to-right; the Y-axis, which moves front-to-back; and the Z-axis, which moves up-and-down.In a four-axis CNC router, there is an additional rotary axis (A-axis) that allows you to do rotary cutting and indexing for making cylindrical/round parts. A typical CNC router only has three axes and moves the cutting tool in the X, Y, and Z axes to remove material from the stock.
