HI there.
We work with plastic injection, and each mould as 2 to 8 cavitys, i was reviewing our Control charts, to make them more easy for the operators, and i run with a problem.
Literature says that for our case we should use Xbar & R charts, my doubt is:
Should i plot the limits (UCL and LCL) for each cavity (and then the chart will be very confusing)
or is there a way for me to find the limits for the group of cavitys?
Thanks.
