Function
Example: The tool breaks during machining. This
triggers a signal that stops the current machining
process and simultaneously starts a subprogram this
subprogram – is called an interrupt routine. The
interrupt routine contains all the instructions which
are to be executed in this case.
When the interrupt routine has finished being
executed and the machine is ready to continue
operation, the control jumps back to the main
program and continues machining at the point of
interruption – depending on the REPOS command.
For further information on REPOS, see Chapter 9,
Path Traversing Behavior, Repositioning.
