If the IR of the workpiece is 5X more than the thickness of the plate, then its position is in the center of the plate thickness. 1) The bending machine slider returns to the starting position and reduces the pressure value of the pressure gauge to the lowest value that just drives the slider movement. Air bending is always the preferred method of bending, but the angle tolerance and the required inside radius sometimes make it necessary to bottom-bend or coin. For the calculated bending force, please confirm: In the bending process, because the inside produces compression, and the outside produces stretching, there is a partial extension of the material, we call it elongation rate.
