<p><P>PROBLEM TO BE SOLVED: To provide improved casting method for a three-dimensional component having intricate internal voids, in relation to a manufacturing process in general, more specifically, casting. <P>SOLUTION: A synthetic model 28 of a component 10 is created from a three-dimensional numerical model 26 thereof. A core is then cast inside the synthetic model 28. The synthetic model 28 can then be removed from the cast core, and then the cast core is used for casting an authentic component therearound. The core is removed from inside the authentic component, which authentic component preciously matches the synthetic model 28 therefor. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
