摘要
对目前常用的无瞬心包络法螺杆加工数控程序中产生误差的原因进行了分析研究，提出了一种校验数控程序精度的分析方法，为改进数控程序提供了理论依据。
This article discussed the causes of errors in NC program of machining screw using non instant center envelope method.An analytical method to check the accuracy of NC program has been given,thus the theory basis of improving NC program has been provided in this article.
