All, I work for a manufacturing company that is divided up into three areas one of which is a Workshop; producing metal parts from plates measuring from 3mm up to 80mm (CNC: Waterjet + Horizontal Boring & Milling). We are trying to come up with the best sampling scheme for the parts being produced. Some of the parts have characteritics requiring 100% inspection but we also have many smaller parts (ribs/sections needed for welded parts) that are produced in lots (up to 80 at a time) affected significantly (in terms of cutting quality) by the waterjet. Can the ISO 2859 and 3951 sampling schemes be used for such an operation?(even if parts aren't technically being 'submitted' as a continuing series of lots).
