Cycles 9.4 Drilling cycles The cycle creates the following sequence of motions: S Approach of the reference plane brought forward by the safety clearance by using G0 S Tapping to the final drilling depth S Dwell time at tapping depth (parameter DTB) S Retraction to the reference plane brought forward by the safety clearance S Retraction to the retraction plane with G0 X G4 G63 G0 RTP RFP RFP+SDIS DP=RFP- DPR SDR SDAC Z Fig. 9-9 Sequence of operations: Tapping with compensating chuck with encoder 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: S Approach of the reference plane brought forward by the safety clearance by using G0 S Tapping to the final drilling depth S Dwell time at thread depth (parameter DTB) S Retraction to the reference plane brought forward by the safety clearance S Retraction to the retraction plane with G0 SINUMERIK 802D, 802D base line 6FC5 698 - 2AA00- 0BP3 (11.03) (OP - T) 9-253
