基于表面成形率的数控加工效率评价方法

Evaluation Method of NC Machining Efficiency Based on Surface Forming Rate

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。

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 effi- ciency 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.
