Abstract
A decoring method and system is provided. The method includes the steps of providing the casting having a core material disposed in the internal passage; providing the decoring apparatus configured to selectively oscillate the casting and selectively rotate the casting; securing the casting in the decoring apparatus; introducing a quantity of shot into the internal passage of the casting; oscillating the casting; and rotating the casting. A decoring apparatus configured to selectively oscillate the casting along a first axis, rotate the casting about a second axis, and rotate the casting about a third axis, is also provided.
Claims6
A decoring apparatus for a casting having an internal passage, the decoring apparatus comprising:
- a stationary base with a frame disposed thereon;
- a rotor rotatably coupled to the frame;
- a clamping assembly coupled to the rotor for securely holding the casting;
- a first motor coupled to the clamping assembly and configured to selectively oscillate the casting along a first axis;
- a second motor coupled to the rotor and configured to selectively rotate the casting about a second axis;
- and
- a third motor disposed directly on the clamping assembly and configured to selectively rotate the casting about a third axis, the third axis having an orientation different from the second axis.
