This study evaluated the effect of three design factors on the dimensional accuracy of the cutting device. A) All coupons used the same gauge width and outer width. B) Coupon length was varied by increasing the gauge length. B) Neck curvature was varied by changing the aspect ratio between the inner and outer radius, where low neck curvatures have the most gradual slope near the gauge region. D) Razor clearance represents the fit between the curved regions of the caul and blade die, where a uniform razor clearance has a consistent gap between engineered parts to accommodate the exact thickness of the razor. All units are in mm.
