Which term describes the rotational movement of a workpiece around the X axis?

• A. A axis
• B. B axis
• C. X axis rotation
• D. Y axis rotation

Answer: (A)

Rotary axes in CNC are named after the axis they rotate about. The axis that turns around the X-axis is called the A axis. This standard (A around X, B around Y, C around Z) gives a concise way to describe multi-axis motion. So describing the rotational movement of a workpiece around the X axis as A axis rotation is the precise, widely used term. Rotation around the Y axis would be B axis, and rotation around the Z axis would be C axis. The phrase “X axis rotation” is descriptive, but the formal name for that motion is A axis rotation.
