平面是机械制造中的主要基面之一。但必须指出,在车间中对加工零件进行百分之百和非一次检验时,标准检验法的效率降低了。这是因为在计算标准测量基面-配合平面的偏差时,对测量结果的数学处理,标准方法太复杂而费力。因此,在生产中有时把测量各 Planes are one of the major foundations in machine construction. However, it must be pointed out that the efficiency of the standard test method is reduced when one hundred percent and non-one inspection of the machined parts is carried out in the workshop. This is because the standard method is too complicated and laborious to math the measurement results when calculating the deviation of the standard measurement base-mating plane. Therefore, in production sometimes measure each
