To provide a cutting method and a cutting device for improving cutting accuracy by preventing deformation by preventing the push-down of a workpiece by an upper cutting blade at the time of cutting (full cut or half cut) of the upper cutting blade. The workpiece W inserted into a hole W1 opened in a sheet WH for a thin work holder is temporarily fastened to the sheet WH for the work holder by being located in a middle region of the thickness of the workpiece W not to be in contact with the upper and lower cutting blades C1 and C2 for the half cut. The workpiece W is half-cut by being shared over the whole width without cutting the sheet WH for the work holder by the upper and lower cutting blades C1 and C2 of required lengths which are longer than the whole width of the workpiece W and shorter than the sheet WH for the work holder. The push-down of the workpiece W by the upper cutting blade C1 at the time of the half-cut is prevented by a lower stripper ST2 fixedly provided in the table surface height of cutting machine 1. The push-up of the workpiece W by the lower cutting blade C2 is prevented by an upper stripper ST1. |
