本标准规定了冲压剪切下料未注公差尺寸的极限偏差的精度等级和剪切下料公差的标注方法。
本标准适用于龙门式和开式剪板机，剪切厚度为12 mm以下、剪切宽度≥90 mm，剪切长度与宽度之比≤5的金属板件或供冲压用板坯。

Scope

This standard specifies the accuracy level of the limit deviation of the untoleranced dimensions of stamping shear blanking and the marking method of shear blanking tolerance. This standard is applicable to gantry-type and open-type shearing machines, which can cut metal plates or blanks for stamping with a shearing thickness of less than 12 mm, a shearing width of ≥90 mm, and a shearing length-to-width ratio of ≤5.
