Hello to all,
I have some doubts regarding how some control methods should be declared in PFMEA.
Here is the context example as stated in the PFMEA:
- Failure mode:
Tube bent out of specification
- Cause of failure:
Tube placed incorrectly in Bending machine (incorrect position)
- Preventive control
Tube position sensor in bending machine.
- Detection control
Process gage with correct route after Bending process.
In order to validate that the sensor in question is working correctly, I have a Master dummy part that should be detected as NOK position.
So the question is:
In the PFMEA, in the same failure mode "Tube bent out of specification", should I add another cause of failure row stating "Position sensor not working properly" and input the Master dummy part validation as both Prevention/Detection controls?
Because in the control plan, I want to input both controls: the position sensor and it's validation method (Master dummy part).
Thanks in advance for any of your opinions/feedback.
