本文运用寿命周期费用（ＬＣＣ）分析方法，对ＣＮＣ机床的使用过程进行了研究，建立下一个数学模型，得出一些有意义的结论。这将有助于对ＣＮＣ机床的前期和后期管理以及设备的投资决策。
In this paper, the life cycle cost (LCC) analysis method is used to study the process of using CNC machine tools. The next mathematical model is established and some meaningful conclusions are drawn. This will help with the early and late management of CNC machine tools and equipment investment decisions.
