13.5Automatic Mode Restart with BLOCK RETURN Condition

the canned cycle restarted by means of condition BLOCK RETURN consists of 3 part

blocks:

1st part block: Positioning in the selected plane (GO X100 Y70)

2nd part block: Positioning to point R (G0 Z2)

3rd part block: Hole machining and retracting to initial level (G98) or to point R (G99).

At the end of all three part blocks the control stops in single block mode. If the canned cycle is programmed with repetition count L the above part blocks are repeated.

2nd case: Interrupting canned cycle and return in the course of positioning in the selected plane

If in the sample cycle the movement is interrupted during moving to position X=100, Y=70

and the interruption point is moved by means of the BLOCK RETURN condition the

movement may be led back to the 1st case, i.e., all axes move to the position valid when the interruption takes place.

3rd case: Interrupting canned cycle and return in the course of positioning to point R

If in the sample cycle the movement is interrupted during positioning to point R=2 in direction

Z and the interruption point is moved by means of BLOCK RETURN condition the movement may also be led back to the 1st case.

4th case: Interrupting and restarting canned cycle in the course of drilling If the canned cycle is interrupted during

hole machining and the process is re- started by means of condition BLOCK

RETURN the movement may also be led back to the 1st case.

Return to Interruption Point after Interrupting Machining in Offset Mode

The following cases refer to axes in the selected plane, when offset mode is on. For interrupt- ing and return axis movements outside the selected plane the cases of state G40 can be applied.
