Abstract:
A method, process, system, and apparatus for straightening of thin tubular shapes. A method of straightening of thin tubular shapes includes: supporting a tubular product between a plurality of first support members and a plurality of second support members of a bending apparatus; applying loads to the tubular product at respective locations along a length of the tubular product using a plurality of actuators of the bending apparatus; and using a recipe-based program to calculate the loads at the respective locations and control the plurality of actuators to apply the loads.
