留磨燕尾导轨尺寸的计算较为繁琐。通常采用圆棒法测量,由工人(或工艺卡片上已给出的)根据圆棒d的大小,计算出测量尺寸L的变化范围,来控制工件的尺寸L_工,此方法一般用于单件、小批加工凸形燕尾导轨(留磨或不留磨)的尺寸测量,但是,它不能正确地反映出角度β的变化。第二种方法是角铁法如图1,同样,它也是由工人根据角铁L_1、L_2实 Grind dovetail rail size calculation is more complicated. Usually measured by the round bar method, the worker (or process card has been given) according to the size of the round bar d, calculate the range of measurement size L to control the size of the workpiece L_ 工, this method is generally used for single However, it does not correctly reflect the change in angle β. The second method is the angle iron method shown in Figure 1, the same, it is also based on angle iron workers L_1, L_2
