Explanation of the parameters
For the parameters RTP, RFP, SDIS, DP, DPR, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
DTB (dwell time)
The dwell time to the final drilling depth (chip breakage) is programmed under DTB in seconds.
SDIR (direction of rotation)
The programmed direction of rotation is active for the distance to be traversed to the final drilling depth.
If values other than 3 or 4 (M3/M4) are generated, alarm 61102 "No spindle direction programmed" is generated and the
cycle is aborted.
Programming example: Fourth drilling
CYCLE88 is called at position X80 Y90 in the XY plane. The drilling axis is the Z axis. The safety clearance is programmed
with 3 mm; the final drilling depth is specified relative to the reference plane.
M4 is active in the cycle.
