Two
production options were considered for the production of the lever arm
-- casting and forging.
- The
production requirement is 2.5 million lever arms per year with requirements for precision
tolerances,
controlled cost, and minimal machining. (The steel alloy is
very hard with
limited machinability.)
- With
those requirements casting is the production method of
choice.
- Casting
produces a near-net shape component with the minimal amount of
additional machining.
