摘要：随着数控技术的发展，在飞机结构件的制造中，高效的数控加工技术成为衡量飞机结构件制造水平的重要指标，而传统方法不能有效地评价或预估零件的加工效率。本文提出了一种基于表面成形率的数控零件加工效率评价方法，并根据实际工程形成了效率基准评价原则，构建了效率基准样本库。结果表明：该方法对项目的成本控制、加工排产准备和承接报价等方面具有指导意义。

Abstract:With the development of NC technique，the manufactory of aircraft structure pays more attention on how to manufact part in a highly efficient way.However，the traditional method on efficiency evaluation can not evaluation parts processing′s efficiency accurately.This paper advances a theory based on surface forming rate and sets up critertion of efficiency and sample library of efficiency.The application results show that the method of efficiency evaluation which based on surface forming rate is absolutely remarkable and takes a good guiding significance.
