Actual AQL Calculation after inspection for a inspection lot

Hi Experts

We have a requirement where we are maintaining different material code based on different barrier and visual AQL level.

Lowest barrier and visual AQL combination material is considered as Lead material and production orders are created against this lead material. (A sample table given below for example)

We are using 04 inspection type and inspecting the inspection lot coming out of order confirmation.

We already have two characteristics for barrier and visual in inspection plan. Sampling procedure S111214L is being used for both the characteristics.

Based on the defect and actual result of characteristics for inspection lot, we want to determine the actual barrier and visual AQL for inspection lot and update the value in some other characteristics.

    Is there an actual question here?

    It appears you need 5 inspection plans. One for each AQL.

    Then assign the two relevant materials to the plan.

    For the barrier spec, one spec is set as the normal spec, the second material spec is set up with a dependent spec.

    • Ok.. so if understand this.. you make material A and inspect it with a barrier spec value of .65 and use a sampling AQL of 1.5. That would be set up with say inspection plan 89.

      You inspect it and if necessary "regrade" the material to a new material of either B thru J. This material is posted to unrestricted inventory.

      I understand the barrier spec, but what I don't understand is the visual AQL. Typically AQL is used to determine the quantity of material to inspect to assure a typical quality level. So are you manually deciding to visually inspect more items when you inspect material A and then recording the AQL value as a test result??

      Then when you regrade the material to a new material, you want the results from the barrier test and the recorded AQL to be available as a result for the material/batch it is regraded too?

      Is this the process you are looking for? If so, those values should all be readily available in batch characteristics if you've linked your MIC's to general characteristics. That would be standard.
