When a program interruption occurs, the immediate need is to retract the tool reliably. If you then wish to continue machining, you acknowledge an NC stop with the “manual traverse” soft key. In this way you make sure that the program continues to be referenced and that in the control, for example, the current condition of cycles remains saved. You then simply withdraw the tool using the axis direction key for the tool axis.
An example: If an interruption has taken place during tapping, then simply retract the tool with the press of a button, reliably and completely without problems, because the TNC suitably interpolates the motion of the spindle.
Machining continues: You then bring the tool back to the position before program interruption with the “approach position” soft key.
If the program run does not continue after an interruption, confirm the NC stop with the “Internal stop” soft key. You can then change the operating mode and retract for example in MANUAL MODE—but without the convenient support of the control. Automatic re-approach is then at first no longer possible.
