Parameters
Parameter Data type Description
RTP REAL Retraction plane (absolute)
RFP REAL Reference plane (absolute)
SDIS REAL Safety clearance (enter without sign)
DP REAL Final drilling depth (absolute)
DPR REAL Final drilling depth relative to the reference plane (enter without
sign)
DTB REAL Dwell time at final drilling depth (chip breakage)
FFR REAL Feedrate
RFF REAL Retraction feedrate
Function
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.
This cycle can be used for reaming of bore holes.
