scope:

This standard specifies the safety requirements for the design, construction, operation and maintenance (including installation, dismantling, and transport) of machining centers and automatic numerically controlled milling, drilling and boring machines (see 3.1).

This standard is applicable to machines where the axes of travel is not greater than 1x1x1 m (39x39x39 in.).

Machining center

A machining center is a numerically controlled machine tool with automatic tool changing capability and work support means capable of multiple functions of drilling, milling, boring or any combination of these operations normally utilizing a rotating tool. This machine operates in a continuous sequence of movements under numerical control (NC).

NOTE - The terms machine and machinery as used throughout this standard mean machining center.
