What does the AUTO ALL AXES key do in zero return mode?

• A. Initiates a tool change
• B. Returns and initializes all axes to machine zero
• C. Performs a diagnostic check
• D. Sets the work coordinate system

Answer: (B)

The function of the AUTO ALL AXES key in zero return mode is to return and initialize all axes to machine zero. This process is critical in CNC operations as it allows the machine to recognize its reference point, ensuring that subsequent movements and operations are based on a known starting position. When the machine is reset to zero, it helps maintain accuracy and repeatability during machining processes by ensuring that all dimensions are referenced from this established point. This operation is often used at the beginning of a machining cycle to establish a clear baseline for further tool paths and operations.
