Title:
MACHINE TOOL AND METHOD FOR SETTING PRESSURIZING FORCE
Document Type and Number:
WIPO Patent Application WO/2024/095430
Kind Code:
A1
Abstract:
The machine tool (10) comprises: a pair of center members (20, 21) that support both end portions of the workpiece (W); a pressing device (36) for applying a pressurizing force to the workpiece (W) by making the pair of center members (20, 21) approach each other in the axial direction (CD); a data acquisition device (32) that acquires basic shape data (DA) about the basic shape of the workpiece (W) or buckling flexure shape data (DB) about the buckling flexure shape of the workpiece (W) in a state in which buckling flexure has occurred as a result of the workpiece W being supported by the center members (20, 21); a calculation device (33) for calculating an optimum pressurizing force (FE) on the basis of the basic shape data (DA) or buckling flexure shape data (DB) and a program (37) for calculating the optimum pressurizing force (FE); and a control device (35) that by controlling the pressing device (36), adjusts the pressurizing force applied to the workpiece W on the basis of the optimum value (FE) for the pressurizing force calculated by the calculation device (33).
