After the metal sheet is grooved, the bending springback will be greatly reduced, but it still exists. Therefore, when planing V-shaped grooves, we must flexibly groove according to the bending angle of the workpiece.
When the metal plate passes through the groove, the bend bounce is greatly reduced, but it still exists. Therefore, when cutting the V-shaped groove, we have to be flexible grooving according to the bend angle of the work piece.
After grooving, the springback of sheet metal will be greatly reduced, but it still exists. Therefore, when planing the V-shaped groove, we should flexibly slot according to the bending angle of the workpiece.<br>
