What function does the JOG LOCK serve in CNC operation?

• A. To initiate emergency stop
• B. To move an axis continuously without holding the key
• C. To reset the machine
• D. To pause the program

Answer: (B)

The JOG LOCK function is critical in CNC operation, as it enables the continuous movement of an axis without requiring the operator to hold down the key. This is particularly useful for making incremental adjustments or repositioning the tool or workpiece while minimizing operator fatigue. When the JOG LOCK is activated, it allows for hands-free movement, making it easier to execute precise movements over an extended period. In contrast, options such as initiating an emergency stop or resetting the machine pertain to safety and recovery procedures rather than facilitating continuous movement. Similarly, pausing the program is about halting operations temporarily, which does not align with the purpose of the JOG LOCK, designed for seamless, uninterrupted movement. Hence, the JOG LOCK's role is fundamentally about providing more control and convenience during the operation of CNC machinery.
