摘要
本文基于所建立的描述切削过程动态稳定性的一个非线性理论模型,研究了机床主轴转速、进给量、切削宽度以及刀具前角和后角对系统动态稳定性的影响规律,并用计算机数字仿真分析了在线调整这些切削参数抑制颤振的效果.
Based on a nonlinear theoretical model developed by the authors for describing cutting dynamic stability, the effects of cutting parameters such as the spindle speed, feed rate, cutting depth, rake angle and clearance angle of cutting tool on the stability are discussed. The effectiveness of on-line adjustment of these parameters for the suppression of chatter is studied by computer-aided digital simulation.
