G69. Drilling canned cycle with variable peck
9.6.1 Basic operation
1. If the spindle was previously running, it maintains the turning direction. If it was not in movement,
it will start by turning clockwise (M03).
2. Rapid movement of the longitudinal axis from the initial plane to the reference plane.
3. First drilling operation. The drilling axis moves in G01 to the programmed incremental depth "B
+ D".
4. Drilling loop. The following steps will be repeated until the programmed machining depth "I" is
reached.
·1· Dwell K, in hundredths of a second, if it has been programmed.
·2· Withdrawal of the longitudinal axis in rapid (G00) as far as the reference plane, if the number
of drillings programmed in J were made, otherwise it withdraws the distance programmed
in "H".
·3· Rapid approach (G00) of the longitudinal axis to a "C" distance from the next peck.
·4· New drilling step. G1 move of the longitudinal axis to the next incremental depth "B and R".
This movement will be carried out either in G07 or G50 depending on the value assigned
to the longitudinal axis "INPOSW2(P51)"
If P51=0, in G7 (square corner). If P51=1, in G50 (controlled round corner).
5. Dwell K, in hundredths of a second, if it has been programmed.
6. Withdrawal at rapid feedrate (G00) of the longitudinal axis to the initial or reference plane,
depending on whether G98 or G99 has been programmed.
