A Study on the Three Dimensional Measurement of Internal Cavity by Using X-Ray NDT Method

The three dimensional measuring method with minimizing operational errors for the arbitrary shaped-internal cavity based on the information of the X-ray nondestructive test is presented. Two experimental tests using artificial cavities were considered in order to verify the availity of PEVACA. In these test, X-ray NDT was conducted for detecting cavities, and the comparion between the calculating values from PEVACA and the real values from measuring the cavities was performed. As a result of this study, three dimensional cavities information using PEVACA are in good agreement with the real measured values within . The computer code, "PEVACA", contributes not only to improvement of data accuracy but also to saving of the work time and data documentation.
