What function does the FEED HOLD button serve on a CNC machine?

• A. To stop spindle movement
• B. To pause tool feed while keeping spindle active
• C. To shut down the entire machine
• D. To resume previous operations

Answer: (B)

The FEED HOLD button on a CNC machine is designed to temporarily pause the tool's movement along its programmed path while keeping the spindle active. This function is crucial for scenarios where the operator may need to inspect the workpiece without interrupting the spindle's rotation, which is essential for maintaining consistent cutting conditions and tool engagement. By utilizing the FEED HOLD feature, operators can halt the feed rate precisely while still allowing the spindle to continue running, facilitating quick checks and corrections without losing programmed movement settings. This capability is particularly useful for ensuring that the CNC operation can be adjusted dynamically without a complete stop of the machining process. The ability to pause the feed can also assist in troubleshooting or adjusting parameters, thus enhancing operational efficiency.
