Cycles
2.4 Drilling cycles
Explanation of the parameters
For an explanation of the parameters RTP, RFP, SDIS, DP, and DPR, refer to the topic
"Drilling, centering - CYCLE81 (Page 112)".
DTB (dwell time)
The dwell time to the final drilling depth (chip breakage) is programmed under DTB in
seconds.
Programming example1: Boring_counterboring
The program machines a single hole of a depth of 20 mm at position X0 with cycle
CYCLE82.
The dwell time programmed is 3 s, the safety clearance in the drilling axis Z is 2.4 mm.
