What is the safest procedure for measuring a part on the milling machine?

The safest procedure for measuring a part on the milling machine involves stopping the machine, deburring, brushing chips clear, and then checking the dimension. This approach emphasizes maintaining a safe working environment while ensuring accurate measurements.

Stopping the machine eliminates the risk of injury from moving parts, providing a safe platform to work on. Additionally, deburring the part removes sharp edges that could cause cuts or injuries. Clearing away chips is essential because it prevents any accumulation of debris that could interfere with the measurement or potentially lead to inaccuracies. By measuring after these safety protocols are followed, the operator can ensure precision without compromising their safety or the integrity of the part being measured.

In contrast, taking the part out and measuring it removes the context of accuracy in relation to the setup, while raising the table without stopping the machine could lead to unsafe conditions. Measuring while the machine is running poses a significant risk because of the potential for accidents if the operator's hands are too close to moving components. Thus, the selected method prioritizes both safety and precision.
