Explanation of the parameters
For the parameters RTP, RFP, SDIS, DP, DPR, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
SDIR (direction of rotation)
This parameter determines the direction of rotation with which the drilling operation is carried out in the cycle.
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: Third drilling
CYCLE87 is called at position X70 Y50 in the XY plane. The drilling axis is the Z axis. The final drilling depth is specified as
an absolute value. The safety clearance is 2 mm.
