This paper presents an industrial application of optical 3-D sensing based on the principle of light sectioning. The presented project aims at an in-process measurement of the bending angle in a commercial bending machine. Air bending is a valuable manufacturing method in a flexible and computer integrated manufacturing system, because it allows forming of sheet metals with a great variety of b...

Abstract In this study, a new test method using protruding punch was proposed, that can separate bending and stretching deformations. test, the blank makes simultaneous contact with head shoulder to ensure constant angle during test. After contact, increasing stroke increases amount of stretch deformation without changing deformation. addition, control inflow materials by controlling BHF, it is...

This research presents a new flexible bending machine and its practical applications. The proposed machine uses a new method. When tubes are fed into the fixed and mobile dies, they are bent by shifting the relative position of the mobile die. The bending radius is controlled by the relative distance and orientation between the mobile die and the tube. The bending angle is controlled by the len...

Springback and longitudinal bow are two major shape defects in gradual forming processes like chain-die roll forming. In this study, the springback of AHSS hat U profiles investigated through experiment finite element simulation. The disparity along direction signifies complex deformation during Based on simulation forming, process realized by sequential die blocks causes bending reverse-bendin...

Probabilistic atlas has broad applications in medical image segmentation and registration. The most common problem building a probabilistic atlas is picking a target image upon which to map the rest of the training images. Here we present a method to choose a target image that is the closest to the mean geometry of the population under consideration as determined by bending energy. Our approach...
