ABSTRACT:
A safety system for a machine tool, e.g. an EDM machine, having a multiplicity of different items of setting procedure to be attended to manually and inspected by the operator before the machine is actuated for performing a given machining operation, employs a loudspeaker associated with the machine. A control unit is used to produce a preselected sequence of multiple, time-spaced electrical signals corresponding to multiple verbal instructions prescribed for alerting the different setting items, respectively, and to apply these signals in that sequence to an electromechanical transducer in the loudspeaker. The transducer responsive to each of the electrical signals produces through the loudspeaker a corresponding unit of the multiple verbal instructions audible to the operator for a corresponding item of the setting procedure. A manual switch is provided so as to be actuated by the operator upon his checking of the item to produce an OK signal therefor, which is applied to the control unit to allow a next of the electrical signals in the prescribed sequence to be issued, thereby permitting the loudspeaker to emit a next corresponding unit of the multiple verbal instructions audible to the operator for a next corresponding item of the setting procedure.
