Abstract: The present invention relates to shearing apparatus, and method of operating the same. The apparatus (10) may include a plurality of spring clamping members (81-88) positioned longitudinally along a first die shoe (502), the clamping members (81-88) positioned in raised stepped sequence from a centerline (800) perpendicular to longitudinal sides of the die shoe (502) to sequentially contact with the sheet material (40). The shearing apparatus (10) may include a die assembly (500) having linear bearings (27) and guide rails (26) for guiding movement of the die shoe (502), and gas springs (28) which return the die shoe (502) to the open position. The shearing apparatus (10) provides straight cuts with a maximum cut-edge tolerance of 0.0015 inch. The shearing apparatus (10) may include a second die shoe (504) having an angled blade (50) to allow a higher shear to break ratio.
