Moldwise SPC analysis


My requirement is to capture Diameter of a product during in-process inspection. Product is manufactured in different moulds, its glass manufacturing industry. Client requirement is to mould wise study of SPC for characteristic "Diameter" during in-process inspection.

How can we maintain master data for this.

1-option) If I go each mould as SPC characteristic with spec of Diameter, I can generate Control chart for mould wise.

But collection of master data for each mold wise will be very huge for each charecteristic.

2-option) Inspection point and maintaining Mold number as inspection point indentifier, In this case client can record Diameter for all running moulds by mentioning mould number in Inspection point identifier, but my control chart generated will not be for Mould wise data but for characteristic "Diameter" only.

Is there any other way to capture mould wise data.

Thanks in advance.
