Which term communicates the location for tool movement along an axis to a CNC machine?

• A. Coordinate code
• B. Address
• C. N code
• D. G code

Answer: (A)

Coordinates convey the tool’s position along each axis, so the term that communicates that location to the CNC is coordinate code. In practice, motion blocks in CNC programs use coordinates (like X, Y, Z) to specify exactly where the tool should move, and those numeric values tell the machine the destination along each axis. G-code is the language that performs the motion using those coordinates, but the specific idea of conveying the location along an axis is captured by the coordinates themselves, i.e., the coordinate information. The other terms don’t directly refer to transmitting axis positions: an address is a general locator, N code is a line-number label, and G code is the broader motion-control language that uses coordinates to move.
