4.10.3.2 #001 – FEEDING ON M-CODE
Parameter #001 determines whether the barfeeder is to begin the feeding only at the
clamping device open or to wait to a special command sent from the lathe.
#001 Description
ON The barfeeder feeds to a special command (M-code) sent from the lathe.
The barfeeder begins to feed the bar after receipt of the M-code.
If the bar is moved to a stopper/to a set position, the barfeeder signs off the
M-code using the M-code end signal (M-fin), and continues to push the bar
to the stopper/remains in the position as long as the clamping device is
open in the lathe.
OFF
The barfeeder feeds only at the clamping device opened. The barfeeder
begins to feed as soon as the lathe opens the clamping device.
The barfeeder terminates the feeding, as soon as the lathe closes the
clamping device.
4.10.3.3 #002 – END OF BAR TIMING
Parameter #002 sets forth the method of sending the End of Bar signal to the lathe if there is
a short bar in the lathe.
#002 Description
Short End of Bar is only sent, if the clamping device is closed. This timing is the
most frequently used timing of the End of Bar signal.
Long End of Bar is sent to the lathe as soon as the barfeeder detects a short bar
in the lathe. The signal is reset by the leading edge of termination of the
second M-code (M-fin signal) at the bar replacement. Thus the signal is
active from the moment of detection of the end of bar to the moment of
completion of the bar replacement.
Mazak End of Bar is sent to the lathe only if the EOB M-code is active.
Standard End of Bar is sent to the lathe as soon as the barfeeder detects a short bar
in the lathe. The signal is reset by the leading edge of M-code for ejection.
Double End of Bar is only sent if the condition for sending of Long end of bar is
fulfilled and at the same time the M-fin signal is not sent. Long End of Bar
signal is thus interrupted if the M-fin signal is sent.
This signal is designed for the lathes which drop the M-code at absence of
the End of Bar signal. These lathes are not able to send the M-code, if the
barfeeder does not signal End of Bar. The barfeeder signs off the M-code by
interruption of the end of bar, and its restart enables the lathe to send the
second M-code at the bar replacement. In particular this can be true for
Boley lathes.
