测量装置介绍本装置用于测试加工方法的精度是否适合于零件图纸给定的精度。即对工艺过程进行测试,确定出加工样本的极差W,算术平均值X和样本标准差S,并以6S作为随机误差的分散范围。选择加工方法时,零件要求的尺寸公差T应略小于加工方法的6S值。本装置由TP801型单板机,DGB-4型电感测微仪,BCT-5C型测微台架及接口电路组
Introduction to the measuring device The device is used to test whether the accuracy of the machining method is suitable for the given accuracy of the part drawing. That is, the process is tested to determine the processing of the sample W, arithmetic mean X and sample standard deviation S, and 6S as a random error dispersion range. When selecting the machining method, the dimensional tolerance T required by the part should be slightly smaller than the 6S value of the machining method. The device consists of TP801 single board machine, DGB-4-type inductance micrometer, BCT-5C-type micrometer and interface circuit group
