Abstract
After a free-form surface is machined on an elongated materialwith a projectionand a blade rootheld, the holding of the projectionis released to release strain generated during machining. Upon release of the holding, the entire elongated materialdeforms, and the projectionmoves 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 materialdue to the weight of the elongated materialis determined, and the projectionis held again at the re-holding position C for further machining the free-form surface on the elongated material
