摘要
通过模态实验测试技术和颤振稳定域仿真分析,研究了"机床-刀具"系统中某些不确定因素对颤振稳定域的影响。研究得出:刀具螺旋槽长度、刀具悬伸量、刀齿数等是影响颤振稳定性的主要刀具几何因素;应根据实际需要严格控制刀具的悬伸量,选择合理的刀具几何参数,以保持系统的高刚性,并合理地选择刀齿数,从而进行高效无颤振加工。通过实例对获得的结论进行了工程应用研究。
Through experimental modal analysis and chatter stability lobes simulation, some uncertain factors of machine tool system affecting chatter stability lobes were studied. The research obtained： the cutter flute length, the cutter overhang, the cutter tooth number etc. were main cutter geometry factors affecting the chatter stability; according to actual requirements, cutter overhang should be strictly controlled and cutter parameters should be chosen properly in order to make the system remain high rigidity and cutter tooth number should be chosen reasonably which results in high performance stable milling process. The conclusion obtained has been verified through the industrial example.
