PROBLEM TO BE SOLVED: To provide a metal plate working machine which can effectively carries out a cut piece by eliminating galling of a cutting hole of a workpiece with the cut piece.SOLUTION: A metal plate working machine includes: a workpiece working position 17 where working is performed so that a cut piece WP is cut and separated from a workpiece on a work tables 3, 7L, 7R; a workpiece moving/positioning means for freely moving and positioning the workpiece in an X- and a Y-axes with respect to the workpiece working position 17; a plurality of workpiece supporting members 29 which are freely advanceable and retractable with respect to a pass line on the top surface of the worktable and can support the workpiece freely movably; a workpiece chuter 21 which is provided closely to the workpiece working position 17 and vertically movably in order to carry out the cut piece WP which has been cut and separated from the workpiece in the workpiece working position 17 from the top surface of the worktable; a carrying-out detector 35 for detecting the carrying-out of the cut piece when the workpiece chuter 21 is lowered; and a controller 37 for performing control for moving the workpiece supporting member 29 vertically and imparting vertical vibration to the workpiece when the carrying-out detector 35 does not detect the carrying-out of the cut piece though the workpiece chuter 21 has been lowered. |
