What term describes words written in numerical data to control tool motion?

• A. G-code
• B. M-code
• C. T-code
• D. S-code

Answer: (A)

Movement commands in a CNC program are issued using a language that encodes coordinates, speeds, and path instructions. This language is G-code. It consists of words and numerical values that tell the machine exactly how to move the tool, such as a command like G1 X10 Y5 F120, which moves in a straight line to X=10 and Y=5 at a feed rate of 120. This is distinct from other codes that handle non-movement functions: M-code handles auxiliary machine actions (like spindle or coolant control), S-code sets spindle speed, and T-code selects tools. So the term describing words written in numerical data to control tool motion is G-code.
