“…Three roll push bending (TRPB), shown diagrammatically in Figure 13 , has been widely used for manufacturing curved hollow profiles [ 56 ]. A push carriage which can rotate around its longitudinal axis is used to grip and move the profile.…”

“…The pressure rollers support the straight part of the profile to avoid premature deflection and the forming roller, which can translate and rotate with respect to the bending roller, controls the final profile curvature. The TRPB process can be controlled to respond to springback, and an in-line approach for real-time evaluation and correction of the springback of bent profiles during the TRPB process was developed based on inertial measurement techniques [ 56 ]. As shown in Figure 13 , a novel mandrel, made of individual rings, was developed to monitor profile curvature after springback.…”

Curved profiles/sections have been widely used for manufacturing lightweight structures with high stiffness and strength due to aerodynamics, structural properties, and design reasons. Structural components fabricated using curved aluminum profiles satisfy the increasing demands for products used in many high-technology industries such as aerospace, shipbuilding, high-speed rail train, and automobile, which possess the characteristics of lightweight, high strength/stiffness relative to weight, superior aerodynamics performance, and aesthetics. In this paper, the advances and trends in forming techniques of curved extrusion profiles of metal alloys have been reviewed. The curved profile forming techniques are classified into three major categories: conventional cold bending technique, stress/moment superposed cold bending technique, and extrusion-bending integrated forming technique. Processes for innovative development in the field of forming curved profiles are identified; the extrusion-bending integrated technique which can directly form the billets into curved profiles by one single extrusion operation possesses the full potential for further innovation. Due to the nature of the research to date, much of the work referred to relates to hollow circular and rectangular tube cross-sections.

“…The collaborations of the procedure parameters and non-straight networks are used to prepare the NN calculation. (Ghiotti et al, 2017) investigated that in an L twisting procedure, the neural systems are utilized to predict the spring-back of a perforated plate or perforated sheets. There are some information parameters used in the neural system such as the proposition of kick the bucket leeway to sheet thickness, clear holder force, pass on, opening size, punch range, and material sort.…”

An ANN or Artificial Neural Network is prototypical that is employed to connect the variety of parameter space. The air bend contains curve force and spring-back. These are predicted through the numerical and semi-logical model. A number of researchers examine these models. A collection of information is fitted by Artificial Neural Network which has high flexibility, the capacity to delineate non-straight connections and parallel usage, collaborations of process parameters, Vigor and the adaptation to non-critical failure are the main characteristics of ANN. Due to these characteristics, and the device of ANN successfully monitors the problems. The significant quality of ANN is that the "U" shaped profile of bending among the information that is involved in the associations of parameters and mind-boggling and the sheet metals bend researchers.
