RPAP REAL Retraction path along the drilling axis (incremental, enter with sign)
POSS REAL Spindle position for oriented spindle stop in the cycle (in degrees)
The cycle supports the 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 drilling 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.
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:
● Approach of the reference plane brought forward by the safety clearance by using 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
● Retraction in the drilling axis to the reference plane brought forward by the safety distance by using G0
● Retraction to the retraction plane with G0 (initial drilling position in both axes of the plane)
Explanation of the parameters
For the parameters RTP, RFP, SDIS, DP, DPR, refer to Section "Drilling, centering - CYCLE81 (Page 126)".
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.
