When I read APQP 2nd ed about CP, I got some confusions:
Chapter 6 Supplement A
Question 1
"No blemishes" is listed in product characteristic, and "Free of blemishes", "flowless" and "sink marks" listed in product/process/spec/tolerance of Method.
My question is why "No blemishes" is a product characteristic while "Free of blemishes", "flowless" and "sink marks" are not?
Question 2
in the same row, "1st piece buy-off" is listed in Evaluation/Measurement/Tech. of Method.
My question is why "1st piece buy-off" is not listed like this: "1st piece" in Size of Sample and "buy-off" in Freq. of Sample?
Question of Supplement B:
In the introduction, it says : The special Product Characteristc is measured 100% by checking electrically for continuity" Why such measurment is not in the CP?
Question of Supplement D1:
In the introduction, it says: The angles on the part are critical and two angles are marked as Special Characteristics. but cannot find the control method in the CP.
Supplement E :
"Lighting inspection code SPE J599 May '81" is in Prodcut/process/Spec./Tolerance of Methods, I think it should be in Evaluation/measurement/Tech.. While "Bubble position on the level to be centered" is in Evaluation/measurement/Tech. of Methods, I think it should be in Prodcut/process/Spec./Tolerance of Methods
Supplement G:
It is talking about preventive maintenance dominant process, but I cannot maintenance activities in the CP, why? Or in other words, how to presence the maintenance activities in a CP?
Supplement H:
"Raw material (pellet dryer) " is listed in Process characteristic. Why it not written as "humidity of raw material" ?
