This American National Standard specifies safety requirements for the design, construction, operation and maintenance (including installation, dismantling and transport) of manually controlled milling, drilling, and boring machines. This standard also applies to devices that are integral to the machine.

These machines may have automatic capability but may not be equipped with automatic tool changing or automatic part handling systems.

This standard applies to various sizes of machines intended to be mounted:

a) on the floor;

b) on a foundation; or

c) on a bench or machine stand.

This standard does not apply to NC milling, drilling and boring machines where manual control is used only to set the machine for automatic production.
