See the following parameters for CYCLE86:
DTB (dwell time)
The dwell time to the final drilling depth (chip breakage) is programmed under DTB in seconds.
SDIR (direction of rotation)
With this parameter, you determine the direction of rotation with which boring is performed 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 not executed.
RPA (retraction path along the 1st axis)
Use this parameter to define a retraction motion along the 1st axis (abscissa), which is performed after reaching the final
drilling depth and oriented spindle stop.
RPAP (retraction path along the boring axis)
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 will be used to drill on the end face in the X-Y plane at position X20 Y20. 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 2 s. The top edge of the workpiece is positioned at Z10. In the cycle, the spindle is to rotate with M3 and to stop at 45
degrees.
