2.6.3 Glossary of Terms
Common (From Lathe) – This is the 24v DC supply voltage from the lathe for signal sent to the
bar feeder control. The voltage cannot be mixed with the bar feeder power supply.
Cycle start (bar change end, program start) – Typically a normally open circuit controlled by
the bar feeder Cycle Start/M-Code Finish relay. Voltage is supplied by the lathe. This circuit lets
the lathe know bar change is completed and to resume the program.
Automatic mode (Automatic mode ON, Bar feeder ready for work, spindle interlock) –
Typically a normally open circuit controlled by the bar feeder. Voltage is supplied by the lathe.
This supplies the lathe with the bar feed automatic signal. If bar feed safety circuit is open bar
feed will not go into auto mode.
End of bar (bar end, block delete, program stop) – Typically a normally open circuit
controlled by the bar feeder end of bar relay. Voltage is supplied by the lathe. This circuit is
closed once the bar feeder has determined the current bar is too short to produce anymore
parts.
Bar feeder on – Typically a normally open circuit controlled by the bar feeder alarm relay.
Voltage is supplied by the lathe.
Lathe Emergency stop (MC ready) – Voltage is supplied by the bar feeder and control is
performed by the lathe. When this circuit is opened it will stop bar feeder operation.
Common (From Bar feeder) – This is the 24v DC supply voltage from the bar feeder used for
signals sent to the lathe control. The voltage cannot be mixed with the lathe power supply.
Lathe manual/auto – Typically a normally open circuit controlled by the lathe. Voltage is
supplied by the bar feed. This circuit can be bypassed if necessary.
Bar change (End of Cycle) – Typically a normally open circuit controlled by the lathe. Voltage
is supplied by the bar feed. This circuit is closed once the lathe has received the end of bar
signal from the bar feed and lathe is machining the last part from the current bar.
Chuck/collet open – Typically a normally open circuit controlled by the lathe. Voltage is
supplied by the bar feed common.
Feed/torque stop- Typically a normally open circuit controlled by the lathe. Voltage is supplied
by the bar feed common.
