Abstract: A tool for shaping an abradable liner of a turbofan engine is disclosed. The turbofan engine includes a shaft to support a fan rotatable about a rotation axis. The abradable liner is configured to surround the fan and has an axial length in the direction of the rotation axis. The tool includes a support configured to be mounted to the shaft and rotatable about the rotation axis. The shaping head is mounted to the support for rotation about the rotation axis and configured to shape the abradable liner by removing material from the abradable liner. A radial position of the shaping head is adjustable relative to the rotation axis. The shaping head may sized to extend substantially across the axial length of the abradable liner.
