4、minal dimension,the actual measurement is allowed to be,so a dimension could be stated as 40.0+/-0.3mm.指定公差的方法之一是极限公差。它决定了偏离公 称尺寸的多少，可允许的实际测量值，所以一个尺 寸可以表述为 40.0+/-0.3mm。,ToleranceandQualityControl公差与质量控制,If the variation can vary either side of the nominal dimension,the tolerance is called a bilater

5、al tolerance.For a unilateral tolerance,one tolerance is zero.如果变动在公称尺寸的两侧，称为双向公差；对 于单向公差，有一侧的公差为零。,ToleranceandQualityControl公差与质量控制,Most organizations have general tolerances that apply to dimensions when an explicit dimension is not specified on a drawing.,很多机构会采用通用公差，用于图样中没有明确 定义的尺寸。,Section1.,T
