Which procedure is considered safe during a milling operation?

In a milling operation, safety is paramount, and the proper procedure is to adjust the workpiece only when the cutter is completely stopped. This practice is crucial because it eliminates the risk of accidental injury that could occur if an operator were to reach for the workpiece while the cutter is in motion. A moving cutter can cause severe lacerations or other injuries, so ensuring the cutter is stationary before making any adjustments helps create a safer working environment.

Other procedures, such as adjusting the work while the cutter is moving, removing chips with hands, or using a rag to wipe the cutter, pose significant risks. These actions can lead to dangerous interactions with the equipment and increase the likelihood of accidents. Hence, the emphasis on stopping the cutter before adjustments is a fundamental safety practice within milling operations.
