- Meet or exceed the strength and durability of the original weldment.
- Choose an alloy grade for sufficient toughness and ductility for
fatigue and impact resistance.
- Design the casting with the selected alloy grade to keep stresses below
the maximum design stress.
- Minimize machining steps and costs.
- Critical dimensional features are --
- the machined center hole in the hub,
- machined mounting holes in the triangular frame,
- as-cast locking holes on the
locking plate.
General tolerances = 30 mils. As-cast hole tolerances are 20 mils.
Machined tolerances are 5 mils.
The surface finish requirement is "clean and smooth" with no
visible surface defects or grinding marks
