What is the function of the M30 command in CNC programming?

• A. End of Program
• B. Optional Stop
• C. Start of Program
• D. Pause Program

Answer: (A)

The M30 command in CNC programming is used to signal the end of a program. When this command is executed, it instructs the CNC machine to finish the current program's operation and reset for the next cycle. In practical terms, it not only marks the conclusion of the program but also typically includes a return to the beginning of the program preparation state. Understanding the role of the M30 command is essential for programming CNC machines effectively, as it ensures that the machine is ready for subsequent operations, maintaining efficient workflow. Other commands, such as those for optional stops or program pauses, serve different functions that do not include ending the program. Recognizing these differences can help in troubleshooting and optimizing CNC operations.
