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.
