利用专用的工作台,在测角仪或自准式测角比较仪上将被检定的角度块与标准角度块进行比较以确定被检定的角度块的角值,是目前角度量值传递的主要方法。但是,在检定过程中,往往由于角度块在工作台上的定位情况不良,直接影响检定结果的可靠性。因为角度块在工作台上的位置,是根据定位销钉来确定的。当我们用镊子将角度块的工作面向定位销钉贴紧时,可能会由于所
Using a dedicated workbench to compare the angle block to be verified with a standard angle block on a goniometer or a self-aligning goniometer to determine the angular value of the angle block being inspected is the primary measure of angle magnitude transfer method. However, in the verification process, the positioning of the angle block on the workbench is often unfavorable, which directly affects the reliability of the verification result. Because the position of the angle block on the workbench is determined by the positioning pin. When we use tweezers to angle the work piece face positioning pin close, it may be due to
