针对高速铣削加工中心设计并进行了静态模态实验、动态空转实验和铣削实验,分别在不同工况下的静态实验、主轴空转不铣削实验、不同铣削参数铣削实验下测得振动信号和动态铣削力。通过对各项实测数据的对比分析,得出各铣削参数与高速铣削系统动态特性的关系,识别特定加工条件下的稳定性铣削极限,为探讨适合高速铣削特点的实验测试及其动态特性优化方法提供依据。
For the high-speed milling machining center, static modal test, dynamic idle test and milling test are designed. The static test under different working conditions, the spindle idle milling test, the vibration signal and dynamic milling measured under different milling parameters force. Through the comparative analysis of the measured data, the relationship between each milling parameter and the dynamic characteristics of high-speed milling system was obtained, and the stability milling limit under specific processing conditions was identified. In order to explore the experimental testing and dynamic optimization method suitable for high-speed milling Provide evidence.
