Which data format is primarily used to program tool motion in CNC systems?

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

Answer: (A)

Tool motion in CNC programming is driven by G-code, a set of standardized commands that specify how the tool moves, where it moves to, and at what speed. G-codes cover modes like rapid travel, linear motion, and circular interpolation, and they carry coordinates (X, Y, Z) and feed rates (F) to define precise toolpaths. This language is built to describe geometry and motion directly. M-code handles auxiliary actions such as turning the spindle on or off and controlling coolant, rather than defining the motion itself. T-code is typically used to indicate a tool number or tool change in a program, not the format for motion commands. N-code usually refers to line numbers in the program, not movement instructions. So, the data format primarily used to program tool motion is G-code.
