Operator and crew procedures: the small habits that double die life
Ten shop-floor habits, grouped into four routines, that separate a 40K-hit shop from a 120K-hit shop on the same die. None of them require new equipment. All of them require that the crew actually do them, every shift, and log the result.

A shop runs the same H13 forge die on three shifts. Day shift averages 110K hits per die. Night shift averages 65K hits per die on the same job, same press, same drawing. The dies, the lube drum, the spray bar, and the preheat oven are identical across shifts. The metallurgy on the failed dies looks no different from the metallurgy on the dies that lasted. Name three operator-controlled habits, from the ten in this lesson, that most likely account for the 45K-hit spread, and state what document the shop should build to close it.
