Abstract
A fugitive pattern of an article to be investment cast wherein the pattern includes a plurality of locator embossments disposed in an array to provide a datum reference system by which the pattern can be held and positioned by a manipulator, such as for example a gripper device to a computer controlled robotic device, for assembly with another component of the pattern assembly. The datum embossments are located on a portion of the pattern that will be removed from the final metallic casting made to replicate the pattern. The casting includes integral cast datum embossments thereon by which the casting can be held and positioned.
