一、现行检测方法及其存在问题 对于燕尾块尺寸的检测,一股推荐采用图1所示检测方法以及这样两个计算公式。实际应用时往往存在一些问题: 1)对于式(1),a必须通过其它手段事先量准,否则不能求解尺寸b。 2)如果要用式(2)来求a,则须先获取尺寸b。无论a角的顶点是否有退刀槽,要获得 First, the current detection methods and their problems For the detection of dovetail size, a recommended test method shown in Figure 1 and the two formulas. In practice, there are often some problems: 1) For equation (1), a must be measured by other means in advance, otherwise the dimension b can not be solved. 2) If you want to use equation (2) to find a, you must first get the size b. Regardless of whether there is an undercut in the a-vertex, it is necessary to obtain it
