测量丝锥几何角度,除了要求检测人员作乘除运算,还要查函数表,既费时间又易出错。这里介绍一种根据已知数据直接查表的方法。如图1所示△—M—γ图表:设已测得丝锥前面与中心的偏位△,从图3中可得公式:sinγ=△/(d/2)或△=d/2sinγ,在丝锥新国标中前 Measuring tap geometric angle, in addition to requiring inspection staff for multiplication and division operations, but also check the function table, both time-consuming and error-prone. Here is a method based on known data directly look-up table. As shown in Figure 1 △ -M-γFigure: Suppose the tap has been measured in front of the center deviation △, available from Figure 3 formula: sinγ = △ / (d / 2) or △ = d / 2sinγ, in the Taps new national standard in the former
