Which axis describes rotation around the X-axis?

Explanation:
In CNC terminology, linear axes (X, Y, Z) handle straight-line motion, while rotational (or rotary) axes handle turning about those directions. Rotation around the X-axis is controlled by the axis that is designated to rotate about that same X direction. That rotational axis is the one associated with X, commonly called the A axis. So the axis description that matches rotation about X is the A axis. For contrast, rotation about Y uses the B axis, and rotation about Z uses the C axis.
