scope:

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

Manual milling, drilling and boring machines These machines utilize manually initiated steps to produce a part by moving a rotating cutter against a workpiece to remove metal and other materials in milling, drilling and boring operations.
