In the shearing of thin tubular workpieces by an electromagnetic forming method, the effects of the shearing are investigated experimentally. The charged voltage of the condenser bank, the width of the shearing parts, the types of materials, and outer diameter thickness of the workpieces are used as experimental parameters. The shearing mechanism is such that the shearing parts are stretched and cut off with their bulging. The cut edges of the shearing have a small shearing droop and a large fracture surface. The rates of the shearing are very fast, and the forming method is excellent. The minimum charged voltages for the shearing increase with increasing the thickness of the workpieces and decreasing the diameter and the width of the shearing parts.
