Abstract:
1. A bending machine for bending a workpiece by cooperation of an upper bending mold and a lower bending mold which are relatively movable in a vertical direction, comprising: an upper table which has an upper mold attachment part which attaches the upper bending mold on a bottom side thereof and extends in a horizontal direction; a lower table which is opposed to the upper table in the vertical direction, has a lower mold attachment part which attaches the lower bending mold on a top side thereof and extends in the horizontal direction; an input part which inputs product information; a bending order determiner that determines a bending order of the workpiece; a mold determiner that determines a mold necessary for bending the workpiece; a layout determiner that determines a layout of the mold; a positioning information calculator that calculates a position of the workpiece with respect to the mold determined by the layout determiner as work position information; and a navigating member which navigates a position of the workpiece to a operator by movement in the horizontal direction on the basis of the work position information calculated by the positioning information calculator.
