Abstract:
1. A method of manufacturing an elongate component comprising: providing a punching apparatus configured to apply a differential contact three point bending load to the elongate component by advancing a punch by a punch travel dpunch at a punch location between two discrete supports by a punch distance, calculating the punch travel dpunch based on a second moment of inertia Ixx of the elongate component at the punch location, the location of the neutral axis Y of the elongate component at the punch location, and a desired plastic deformation dplastic of the component at the punch location, wherein second moment of inertia Ixx, the neutral axis Y and the desired plastic deformation dplastic are related as follows: wherein Bi is calculated based on the following relationship: where BBij are constants, delastic is an elastic punch limit of the elongate component.
