Abstract
Spin testing testing of the integrated bladed rotors or blisks is being increasingly used for the better understanding and validation of life and integrity. The test is carried out in various steps and goes thorough rigorous monitoring and inspection during and after each set of testing cycles. The current paper gives an overview of the dimensional and geometrical verification on a Coordinate Measuring Machine (CMM) carried out at the pre-test and post-test levels. An overall measurement strategy and plan followed for the verification is explained. The measurement data obtained under the controlled conditions is analysed for deviations from the pretest values conditions for the validation.
