    I’v got e headache from not have any good ideas.
     
    Problem.
     
    A machine produces items (16 up in each operation/takt). There is a suspicion that one operation may sometimes produce bad parts (1 or more of the 16). The frequency for inspection are 16/750 parts and the test are “GO/NO GO”. It may also be that the failure sometimes are temporary and missed in inspection. Approximately failure has been detected after 3000-5000 pcs.
    (cleaning of tool needed)
     
    The question, from what given above, how to make a good measurement. What are proven by the tests done.
     
    What I am looking for are to minimize the test and give some recommendation for preventive maintenance. I’m thinking in terms of MTTR, MTTF.
     
    Any suggestions or ideas to get my brain going would be helpful =)
