Siemens sinumerik 808d Programming And Operating Manual page 137

You use this parameter to define a retraction movement along the drilling axis, which is
executed after the final drilling axis has been reached and oriented spindle stop has been
performed.
POSS (spindle position)
Use POSS to program the spindle position for the oriented spindle stop in degrees, which is
performed after the final drilling depth has been reached.
Note
It is possible to stop the active spindle with orientation. The angular value is programmed
using a transfer parameter.
Cycle CYCLE86 can be used if the spindle to be used for the boring operation is technically
able to go into position-controlled spindle operation.
Programming example: Second boring pass
CYCLE86 is called at position X70 Y50 in the XY plane. The drilling axis is the Z axis. The
final drilling depth is programmed as an absolute value; no safety clearance is specified. The
dwell time at the final drilling depth is two seconds. The top edge of the workpiece is
positioned at Z110. In the cycle, the spindle is to rotate with M3 and to stop at 45 degrees.
