ABSTRACT:
There is disclosed a protective system for preventing damages to a tool and a work or tool changing mechanism component parts due to any interference between the tool and the work during the tool changing operation by an automatic tool changing apparatus in a numerical control machine tool such as a machining center.
The protective system monitors the load current of a driving motor for the automatic tool changing apparatus, whereby when the load current reaches an abnormally high current value during the operating period excluding the motor starting period, the operation of the automatic tool changing apparatus is reversed and then stopped.
