Function
A typical example should clarify the function of an interrupt routine:
The tool breaks during machining. This triggers a signal that stops the current machining
process and simultaneously starts a subprogram – the so-called interrupt routine. The
interrupt routine contains all the statements which are to be executed in this case.
When the interrupt routine execution has finished 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
