SPC could be used to controlling the process for APS

Thanks for the response Gordon.
I would like to understand how SPC could be used to controlling the process. By utilising run charts to assess performance, it should be possible to identify potential problems before they become problems and enable you to avert a non-conforming coating before it is too late. Just as an example ~ wear on nozzles. How often should nozzles be changed? How can you monitor their wear such that they are replaced before they degrade and start affecting / contaminating a coating? What techniques do people use to detect wear etc etc. In a shop floor environment, not all factors can be watched by an operator, (maybe possible in a lab environment) so if only three (for the sake of argument) can be monitored, what three 'key process variables' would be best to monitor.
Any help from anyone greatly received.
