What is the primary purpose of the Jog mode on a CNC machine?

The primary purpose of the Jog mode on a CNC machine is to manually move the machine axes. Jog mode allows operators to control the movement of the machine in specific directions and precise increments, which is essential for tasks such as positioning a workpiece, setting tool offsets, and aligning the machine axis with features on the workpiece.

This mode enables operators to have more hands-on control over the machine, which is particularly useful during setup and troubleshooting when precise positioning is required. Operators can move the CNC axes in a controlled manner without executing a full program, which offers flexibility during the setup phase.

In contrast to other functions, such as executing a program run or changing tool settings, the Jog mode focuses specifically on movement and positioning rather than automated processes or adjustments.
