Subject: QS 9000: 4.20 - s.p.c
Date: Wed, 20 Sep 2000 10:48:39 -0400
Is using s.p.c. for economic reasons (savings in material usage ), as opposed to product / specification control reasons required to meet a 1.33 CpK minimum?
Specifically, our processes are component-dominant ( if the molds are manufactured correctly all produced parts produced meet spec. ) and set-up dominant ( 1st part meets spec. = all meet spec. ). We monitor part thickness on an X bar / R chart, with a goal of producing parts that are not too thick / heavy. Is this control subject to QS 9000 requirements? Thanks!
