PURPOSE:To know in advance an actual bending state of a work by displaying graphically a motion executed until a bend of a lumping die, a die, a punch, or a work is completed, prior to positioning in a numerical control device for a press brake. CONSTITUTION:A work to be worked 7 is bent between a punch 6 and a die under said punch, and worked to a shape of a bent work 8. In this case, first of all, a bending program is generated in the first process, subsequently, a motion of the work 7, the die or the punch 6 and a bumping die 9 is displayed by a graphic display of a bend of a process 5, and a bending to be executed subsequently is confirmed. Thereafter, in the same way as before, positioning of the bumping die 9 and a stopper of the punch 6 and the die is executed in the process 2. The unworked work 7 is moved until it hits against the bumping die 9 in a process 3, and thereafter, bent by the punch 6 in a process 4, and returned again to the process 5. |
