答案：The amount of material required for the bend must be determined to assure that the final dimensions wilt be correct. Bending a strip of metal compresses the material on the inside of the curve, and stretches the material on the outside of the curve. However, in the approximate center between these two extremes is a space that is neither stretched nor compressed which is called the neutral axis. When making a bend to exact dimensions the length of the neutral line must be calculated so enough material can be allowed for the bend. Bend allowance depends on four factors: (l)the degree of bend, (2) the radius of the bend, (3) the thickness of the metal, and (4) the type of metal used. To save time in calculation of bend allowance, formulas and charts for various angles, radii of bends, material thickness and other factors have been established.必须确定弯板所需的材料量，以确保最终尺寸正确。弯曲金属条会压缩曲线内侧的材质，并拉伸曲线外侧的材质。然而，在这两个极端之间的近似中心是一个既不拉伸也不压缩的空间，称为中性轴。在进行精确尺寸的弯曲时，必须计算中性线的长度，以便能够为弯曲提供足够的材料。弯曲裕度取决于四个因素：（1）弯曲程度，（2）弯曲半径，（3）金属厚度，和（4）所用金属类型。为节省弯板余量计算时间，建立了各种角度、弯板半径、材料厚度等因素的计算公式和图表。
