摘要
在分析微细铣削成形条件和加工要求的基础上,开发了一套微型铣床系统.研究了机床主轴激励、频响函数及其振动性能,并通过增加阻尼和改变支撑部件刚度等方法探讨了提高系统动力学性能的方法,大大减小了机床系统的振动.通过对具有复杂介观尺度特征的零件加工,表明了采用微型机床开展介观尺度铣削的加工精度和加工能力.
This paper carried out experimental studies on meso milling process with miniaturized machine tool. First, a high precision meso scale machine tool system was developed for meso machining research. Then, experiments were performed to examine and improve the dynamic performances of the meso scale machine tool. Finally, some performance tests were carried out to evaluate the capability of the machine tool. Meso scale milling process is fully proved to be feasible for the fabrication of meso scale parts.
