建立了DMU-70V五轴数控高速加工中心主轴-夹具-刀具系统的有限元模型，并利用动态测试的方法对有限元计算结果进行验证；
The FEM(finite element method) of the main shaftclamping apparatus-cutter system for DMU-70V NC high speed machining was built, and the results of the FEM were validated using dynamic test.
由于加工中心的辅助时间已经压缩得很短，配套夹具的装卸不能占用太多时间。
Because the assistant time of machining center has compressed very short, and the supporting fixture of loading and unloading can't takes too much time.
加工中心机床是机床中自动化程度较高、工序较为集中的机床之一，应用传统的夹具使加工中心的优越性很难发挥。
Machining center is one type of machine tools having high automation and preforming more operations. But it is difficult to bring the advantage of machining center into play with traditional fixture.
