Title:
WORKPIECE BENDING METHOD AND WORKPIECE BENDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/134970
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a workpiece bending method and a workpiece bending apparatus which enable appropriate setting of a trajectory of a bending implement on the basis of a pre-processed shape of a workpiece and an intended post-processed shape of the workpiece. This workpiece bending method is for conducting bending on a flange WF of a workpiece Wa by means of a processing roller 10, the method comprising: a step for obtaining a pre-processed angle θ0 of the flange WF before processing and a flange length L of the portion of the flange WF to be bent; a trajectory determination step for determining a path (trajectory) of the processing roller 10 on the basis of the pre-processed angle θ0, an intended angle Ψ after processing, and the flange length L; and a processing step for moving the processing roller 10 in a prescribed direction in accordance with the path determined in the trajectory determination step and then bending the flange WF until the intended angle Ψ is achieved.
