双电主轴双刀车削车铣复合中心的切削振动特征分析

摘要

The method of turn-milling center on slender shaft turning is double-spindle clamping and symmetric double-tool cutting.Through the turning testing on turn-milling center, can get rotation characteristics of two motorized spindles and turning characteristics with one tool and two symmetric tools.It can offer reference to the decision of cutting parameters and improvement of machining accuracy by learning vibration characteristics of tools and workpiece in turning.%由于车铣复合中心对细长轴的车削加工方法采用的是双电主轴夹持,双刀对置车削.通过对车铣复合中心的切削测试,得出车锐复合中心双电主轴的旋转特性,单刀车削加工特征以及双刀对置加工特性.测试加工状态下的刀具和工件的振动特性,为加工参数的确定以及机床精度的调整和改善提供参考.
