Sinumerik CYCLE82 Format

CYCLE82 (RTP, RFP, SDIS, DP, DPR, DTB)

RTP  Retraction plane (absolute)
RFP  Reference plane (absolute)
SDIS Safety distance (enter without sign)
DP    Final drilling depth (absolute)
DPR  Final drilling depth relative to reference plane (enter without sign)
DTB  Dwell time at final depth (chip breaking)

Sinumerik CYCLE82 Drilling Counterboring Cycle

The tool drills at the programmed spindle speed and feedrate to the entered final drilling depth (DP or DPR). A dwell time (DTB) can be allowed to elapse when the final drilling depth has been reached.

Sinumerik CYCLE82 Working

1: the drill will rapidly reach the start point (RFP + SDIS).
2: with given feed-rate will complete final drilling depth or hole depth (DP or DPR).
3: dwell for specified time (DTB) at bottom of hole.
4 : the tool will retract rapidly to Return plane (RTP)
