Development of a New 3D Tube Bending Machine Using Parallel Mechanism (The Second Report)

Abstract

A new flexible bending machine for tubes and profiles has been invented. The machine uses a new (MOS) method. When tubes are fed into a guide cylinder and bending die, they are bend by shifting the relative position of tube. The bending radius is controlled by the relative distance between the die and the tube .The bending angle is controlled by the length of fed tube. The relative distance and the fed length are controlled by a parallel kinematic structure using AC servo motors and a CNC. Making use of the parallel kinematic mechanism serves not only to achieve a complete motion along six axes and to manufacture at high productivity, but also to obtain a high dynamical motion of the bending machine. In this report, CNC and CAM system of the flexible bending machine are explained.
