DTD (dwell time at final drilling depth)
The dwell time at final drilling depth can be entered in seconds or revolutions.
DIS1 (programmable limit distance for VARI=1)
The limit distance after re-insertion in the hole can be programmed.
The limit distance is calculated within the cycle as follows:
●
Up to a drilling depth of 30 mm, the value is set to 0.6 mm.
●
For larger drilling depths, the limit distance is the result of
(RFP + SDIS – current depth) / 50. If this calculated value >7, a limit of 7 mm, maximum, is applied.
Programming example1: Deep-hole drilling
This program executes the cycle CYCLE83 at the positions X80 Y120 and X80 Y60 in the XY plane. The first drill hole is
drilled with a dwell time zero and machining type chip breaking. The final drilling depth and the first drilling depth are entered
as absolute values. In the second cycle call, a dwell time of 1 s is programmed. Machining type chip removal is selected, the
final drilling depth is relative to the reference plane. The drilling axis in both cases is the Z axis.
