Fu n ction
The tool drills at the programmed spindle speed and feedrate velocity to the entered final drilling depth.
The inward and outward movement is performed at the feedrate assigned to FFR and RFF respectively.
Se quence
Po sition reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
Th e 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 a 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 more information about the parameters RTP, RFP, SDIS, DP, DPR, see Section "Drilling, centering - CYCLE81
