在万工显上对图1所示的尺寸l进行测量时,因交点O难找而使看起来简单的测量变得非常棘手。这里介绍一种方法供大家参考。 1.将工件置于工作台上。调整工作台,使目镜中纵向米字线和AB边重合(如图2),记下读数x_1;再移动横向滑板,使目镜中纵 In all the work on the size shown in Figure l measurements, due to difficult to find the intersection point O makes the measurement looks simple is very tricky. Here’s a way for your reference. 1. Place the work piece on the workbench. Adjust the workbench so that the eyepiece vertical meter line coincides with the AB (Figure 2), write down the reading x_1; and then move the horizontal slide to make the eyepiece vertical
