Boring - Cycle86 - Siemens SINUMERIK 808D ADVANCED Programming And Operating Manual

DTB (dwell time)
The dwell time to the final drilling depth is programmed under DTB in seconds.
FFR (feedrate)
The feedrate value programmed under FFR is active in drilling.
RFF (retraction feedrate)
The feedrate value programmed under RFF is active when retracting from the hole to the reference plane + safety
clearance.
Programming example: First drilling
CYCLE85 is called at position Z70 X50 in the ZX plane. The drilling axis is the Y axis. The value for the final drilling depth in
the cycle call is programmed as a relative value; no dwell time is programmed. The workpiece upper edge is at Y102.
