OPERATION
538
The chuck–tailstock barrier function prevents damage to the machine by
checking whether the tool tip fouls either the chuck or tailstock.
Specify an area into which the tool may not enter (entry–inhibition area).
This is done using the special setting screen, according to the shapes of
the chuck and tailstock. If the tool tip should enter the set area during a
machining operation, this function stops the tool and outputs an alarm
message.
The tool can be cleared from the area only by retracting it in the direction
opposite to that in which the tool entered the area.
