螺纹环规的验收,应以校对量规旋合法检验为准,而双球量法测量螺纹中径,仅仅用作工艺分析,而且必须自制最佳钢球,并修正制造误差。本人在文章中,阐明了螺纹量值传递系统,以及螺纹量规的检验原则——泰勒原则。图6表1。
The acceptance of thread loop gauge shall be based on the proof test of proofing gauges, while the double-gauge method shall measure the thread diameter only for process analysis, and the best steel ball shall be made and the manufacturing error shall be corrected. In my article I elaborated on the thread delivery system and the principle of thread gauging - Taylor’s principle. Figure 6 Table 1.
