Question

Which of the following codes is used to rotate the spindle of the CNC machine tool in clockwise direction?

• A. M04
• B. G03
• C. G04
• D. M03

Hint:

Always check the correct M-code for spindle rotation direction in CNC programming to ensure proper tool operation.

Answer 1

The Correct Option is A

In CNC programming, the code M04 is used to rotate the spindle in a clockwise direction. M codes are generally used to control auxiliary machine functions such as spindle rotation, coolant activation, and tool changes. G codes like G03 and G04 are used for different functions in the CNC program, with G03 specifically being used for counterclockwise circular motion.
