<p>A synthetic model (28) of a component (10) is created from a 3-D numeric al model (26) thereof. A core (42) is then cast inside the synthetic model (28) . The synthetic model (28) may then be removed from the cast core (42), and then t he cast core (42) is used for casting an authentic component (10) therearound. The core (42) is removed from inside the authentic component (10), which authentic component precisely matches the original synthetic model (28) therefor.</p> |
