Problem with "failure mode” interpretation in PFMEA (Process FMEA)
I have a problem with "failure mode” interpretation in PFMEA.
For me “failure mode” is a problem with the product after operation. For my friend “failure mode” is a problem with the operation.
For example:
In material cutting operation blunt/damaged tool irregularly cuts material.
1.For me:
-Cause: blunt/damaged tool in machine
-Failure mode: irregularly cut material (product out of specification)
-Effect: scrap, customer complaint, customer line stop
2.For my friend:
-Cause: incorrect tool change period, lack of tool check during setup
-Failure mode: blunt/damaged tool in machine
-Effect: irregularly cut material (product out of specification)
My questions:
A.Which way is better?
B.Which way is correct?
C.Is it possible - both ways are correct?
