So what happens is that the recurring set up operations of the machines technical parameters are less and less in charge of the operator and more and more an automated mechanism of information transmission from ERP to the machine. From this view, the role of the operator changes and grows qualitatively: the operator is not a person in front of a machine to carry out tasks now taken over by robotics, but an operator extremely competent on that machine: he has always its parameters under control in order to optimize quality and repeatability of the process.
