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)
SDIR INT Direction of rotation
Values: 3 (for M3), 4 (for M4)
Function
The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth.
During drilling 3, a spindle stop without orientation M5 is generated after reaching the final drilling depth, followed by a
programmed stop M0. Pressing the following key continues the retraction movement at rapid traverse until the retraction
plane is reached:
Sequence
Position reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
The cycle creates the following sequence of motions:
● Approach of the reference plane brought forward by the safety clearance by using G0
● Traversing to final drilling depth with G1 and the feedrate programmed prior to the cycle call
● Spindle stop with M5
● Press the following key:
● Retraction to the retraction plane with G0
