Which setting allows an operator to single step through a CNC program using the jog handle?

• A. Single Block mode
• B. Jog Handle setting
• C. Program Override
• D. Manual Control

Answer: (A)

The setting that enables an operator to single step through a CNC program using the jog handle is Single Block mode. This mode is specifically designed for testing and debugging CNC programs, allowing the operator to run the program one line or block at a time. When Single Block mode is engaged, the CNC machine pauses after executing each command, which gives the operator the opportunity to check for correct operation, adjust parameters, and ensure everything is functioning as intended before proceeding to the next command. This level of control is crucial for avoiding errors and ensuring the safety and precision of the machining process. In contrast, the Jog Handle setting typically allows the operator to manually move the machine's axis to different positions but does not provide the single-step functionality tied to program execution. Program Override would allow adjustments to the feed rate or speed during program execution but does not facilitate the step-through capability. Manual Control provides direct control over the machine’s movements but is not linked to executing the program step by step. Therefore, Single Block mode is the only setting that combines the aspects of program execution with the ability to pause and verify operations.
