Mistake proofing
Mistake proofing
(OP)
We are a commercial heat treating plant who is currently undergoing our QS9000 registration. I am having trouble defining mistake proofing. None of he manuals that we have give a specific definition, only that verification by an operator ( visual ) is not enough. Any information on mistake proofing would be appreciated.
Thanks





RE: Mistake proofing
- Using locating holes and pins to orient a part in the correct position.
- Designing a fixture so that an incorrect size part won't fit.
- Designing tooling so that it cannot physically make a defective part.
The main focus should be (1) don't make a bad part, and (2) parts and assemblies should be "self-inspecting".
Hope this helps!
