In order to achieve the optimal layout of ceramic core locators, improve turbine blade casting ceramic core positioning accuracy and high yield investment casting parts, the ceramic core locator optimization is proposed and studied by Greedy algorithm and Interchange algorithm. Based on ceramic core positioning error transfer chain, the optimal layout of ceramic core locators is solved by using greedy algorithm and Interchange algorithm. At the same time, computation accuracy and computation time is compared and studied. The result shows that the computation accuracy of Greedy algorithm is better and the computation time of Interchange algorithm is better. The study is of great importance to achieve the optimal layout of ceramic core locators in engineering practice.
