The cycle creates the following sequence of motions:
● Approaching the position of safety distance relative to the reference plane with G0
● Traversing to the final drilling depth with G1 and at the feedrate programmed under the parameter FFR
● Dwell time at final drilling depth
● Retracting to the position of safety distance relative to the reference plane with G1 and the retraction feedrate defined by
the parameter RFF
● Retracting to the retraction plane with G0
Explanation of the parameters
For an explanation of the parameters RTP, RFP, SDIS, DP, and DPR, see Section "Drilling, centering - CYCLE81
(Page 152)".
See the following parameters for CYCLE85:
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)
