Programming and Operating Manual (Turning)

The feedrate value programmed under RFF is active when retracting from the hole to the reference plane + safety
clearance.
Programming example: First boring pass
CYCLE85 is called at Z70 X0. The drilling axis is the Z axis. The value for the final drilling depth in the cycle call is
programmed as a relative value; no dwell time is programmed. Z0 is on the surface of the workpiece.

Programming
CYCLE86 (RTP, RFP, SDIS, DP, DPR, DTB, SDIR, RPA, 0, RPAP, POSS)
Retraction plane (absolute)
Reference plane (absolute)
Safety clearance (enter without sign)
Final drilling depth (absolute)
Final drilling depth relative to the reference plane (enter without sign)
Dwell time at final drilling depth (chip breakage)
SDIR INT Direction of rotation
Values: 3 (for M3), 4 (for M4)
Retraction path along the 1st axis of the plane (incremental, enter with sign)
Internal parameter; only the default value 0 is possible
Retraction path in drilling axis (incremental, enter with sign)
Spindle position for oriented spindle stop in the cycle (in degrees)
The cycle supports boring of holes with a boring bar.
The tool drills at the programmed spindle speed and feedrate velocity up to the entered drilling depth.
With boring 2, oriented spindle stop is activated once the drilling depth has been reached. Then, the programmed retraction
positions are approached in rapid traverse, and from there the retraction plane is approached.
CYCLE86 can be applied on a turning machine only with TRANSMIT in the G17 plane and with a driven tool. Fore more
information about TRANSMIT function, see Section "Face milling on turned parts (TRANSMIT) (Page 138)" .
Sequence
Position reached prior to cycle start:
The drilling position is the position in the two axes of the selected plane.
The cycle creates the following sequence of motions:
● Approaching the position of safety distance relative to the reference plane with G0
● Traversing to final drilling depth with G1 and the feedrate programmed prior to the cycle call
● Dwell time to final drilling depth
● Oriented spindle stop at the spindle position programmed under POSS
● Traverse retraction path in up to three axes with G0
● Retracting in the boring axis to the position of safety distance relative to the reference plane with G0
● Retracting to the retraction plane with G0 (initial drilling position in both axes of the plane)
