FACE MILLING (Cycle 233, DIN/ISO: G233) 5.9

Please note while programming:

Pre-position the tool in the machining plane to the
starting position with radius compensation R0. Keep
in mind the machining direction.
The TNC automatically pre-positions the tool in
the tool axis. Pay attention to Q204 2ND SET-UP
CLEARANCE.
Enter Q204 2ND SET-UP CLEARANCE so that no
collision with the workpiece or the fixtures can occur.
If Q227 STARTNG PNT 3RD AXIS and Q386 END
POINT 3RD AXIS are entered as equal values, the
TNC does not run the cycle (depth = 0 has been
programmed).
Danger of collision!
Enter in machine parameter displayDepthErr
whether the TNC should output an error message
(on) or not (off) if a positive depth is entered.
Keep in mind that the TNC reverses the calculation
for pre-positioning if the starting point is less than
the end point. This means that the tool moves at
rapid traverse in the tool axis to set-up clearance
below the workpiece surface!
