Abstract: The invention relates to a method for straightening non-straight bar-shaped material (1) by determining a target plastic deformation (s_soll) at a forming position (12) of the bar-shaped material (1), moving a straightening hammer (8) with integrated measuring probe (7) to the forming position (12), a first forming stroke (h_1) of the straightening hammer (8) is carried out, an actual plastic deformation (s_ist) caused by the first forming stroke (h_1) is determined by means of the integrated measuring probe (7), a second forming stroke (h_2) is determined from the actual plastic deformation (s_ist) caused by the first forming stroke (h_1) and the target plastic deformation (s_soll).
