Method for machining free-form surface on elongated material

After a free-form surface is machined on an elongated material 1 with a projection 3 and a blade root 4 held, the holding of the projection 3 is released to release strain generated during machining. Upon release of the holding, the entire elongated material 1 deforms, and the projection 3 moves fro...

Zusammenfassung:	After a free-form surface is machined on an elongated material 1 with a projection 3 and a blade root 4 held, the holding of the projection 3 is released to release strain generated during machining. Upon release of the holding, the entire elongated material 1 deforms, and the projection 3 moves from a holding position A to a strain-released position B. A re-holding position C obtained by correcting the position B by the deformation amount of the elongated material 1 due to the weight of the elongated material 1 is determined, and the projection 3 is held again at the re-holding position C for further machining the free-form surface on the elongated material 1.
