为了测量图1所示的球面配流盘球面至弧面高度H,我们研制了图2所示的简易测具。根据该零件特点,取垂直于轴线的φ64mm球冠平面为工艺基准。求出球冠高度h_1及弧面高度h_3,那么工艺尺寸h_2=H-h_1-h_2。使 In order to measure the spherical face plate to the arc height H shown in Figure 1, we developed a simple measuring tool shown in Figure 2. According to the characteristics of the part, take the plane perpendicular to the axis of φ64mm for the process of benchmarking. Find the crown height h_1 and arc height h_3, then the process size h_2 = H-h_1-h_2. Make
