Hi all, I work in a die casting company. My company implement SPC in our process.
But, we only use 2 rules of abnormal graph.
rules 1 : ( Point out of control limit )
rules 2 : ( 4 out of 5 point in a row on same side of centerline )
I want to explain to management that we should use all kinds of abnormal charts. I got this knowledge when in my old company. but I do not have a qualified journal as a reference to management.
please share with me if you have the journal. Thank you..
