Final answer:
Metal chips and dirt should be cleaned from a lathe using a brush to ensure safety and protect the machinery, not with bare hands.
Explanation:
Accumulated metal chips and dirt are cleaned from the lathe with a brush, never with your hands. This is important for safety reasons as well as to preserve the integrity and cleanliness of the machinery's parts. When cleaning sensitive equipment such as optical components, a specific cleaning process is used where a wet cloth is utilized only once to prevent the previously collected debris from scratching the surface.
