Which part of the control keypad allows movement of a selected axis?

• A. Jog keys
• B. Program edit key
• C. Cycle start key
• D. Home key

Answer: (A)

The jog keys are specifically designed to facilitate the manual movement of the selected axis on a CNC machine. When an operator wants to position the tool or workpiece accurately, the jog keys provide precise control over the movement in defined increments. This allows for fine adjustments and positioning during setup or while making changes in the program. In contrast, the program edit key is used for modifying or entering CNC programs, which does not directly impact physical movement. The cycle start key initiates the programmed machinery cycle, meaning it starts the automated processes already defined in the CNC program rather than providing manual control. The home key, while important for returning the machine to a predefined origin point, does not provide the same level of precise control for positioning that the jog keys do. Hence, the jog keys are the correct choice for enabling movement of a selected axis.
