Press brake bending is a commonly used process for sheet metal part fabrication. It has been observed that the final bend angle, which is the angle achieved upon removal of the punch, is smaller than the initial bend angle. This springback is due . A kind of U type 90°or V type 90°bending springback testing die was set up to discuss the bending springback . The springback of material can be masteried through setting up of bending springback adjusting test die without prior calculation . In order to adjust the bending angle , the T type slide seat and bending press plate were used and the adjusting of bending . Springback is the geometric change made to a part at the end of the forming process when the part has been released from the forces of the forming tool. . Upon completion of sheet metal, deep-drawn and stretch-drawn parts spring back and thereby affect the dimensional accuracy of a finished part. . When the force that caused the bend is . A model is proposed for analysis of the unloading springback of sheet metal foils in micro-bending process based on the surface layer model. FEM simulation based on the proposed model is conducted. The grain size and geometry effects in micro-bending are studied. How the size effects affect the springback of sheet metal in micro-bending is revealed.

The springback prediction of bending operation using FEA has been employed by many in the past. For instance, Cho et al. [2] carried out numerical investigation on springback characteristics in plane strain ‘U’ bending process by thermo-elastoplastic FEA. Li et al. [5] mainly dealt with material hardening and modulus to analyze ‘V’ bending by simulation and showed .Eventually the material reaches its yield point and permanent deformation of the metal will occur. Zone 2 shows that as the work exerted on the sheet metal increases the metal begins to bend, however in this region it will return slightly. The amount that it returns is a property of the metal as well as the tooling used to bend it.An example is to reduce sidewall curl by replacing sheet metal flowing through draw beads and over a die radius with a simple 90 degree bending operation. . The rail cross section in sketch A of Figure 13 does not allow the use of over-bending for springback compensation in the forming die. In addition, this design likely leads to severe .

In sheet metal stamping, springback manifests as a discrepancy between the final part geometry and the intended shape defined by the stamping die’s working surface. This deviation often results in parts falling outside specified tolerance ranges, potentially compromising the assembly precision and overall quality of the final product.

Sheet-metal bending can be used for manufacturing automobile body panels, steel furniture, fridges, electronic casings, and brackets.
