Abstract: A processing machine for performing a bending operation on a workpiece includes a die, a punch movable in a first direction for pressing the workpiece against the die, a slide member movable in a second direction perpendicular to the first direction, a first cam device that moves the punch toward the die for deforming the workpiece when being actuated by movement of the slide member, a second cam device that moves the punch for pressing a surface of the workpiece when being actuated by movement of the slide member. The pressure angle of the second cam device is smaller than a pressure angle of the first cam device. The processing machine further includes a drive member configured to move the slide member such that the second cam device is actuated after the first cam device is actuated.
