摘要
提出一种基于频域分析的两自由度工件表面位置误差预测方法。在铣削加工过程中强迫振动的条件下,结合刀具和工件之间的相对位移对铣刀路径进行定义,建立铣削过程中x向和y向的切削力模型。根据实验要求建立了两自由度可调谐柔性平台,对工件系统和刀具系统频响函数进行测量,并结合稳定性图表选择合适的主轴转速进行实验。
A prediction method of surface location error of two degree of freedom workpiece based on frequency domain analysis is proposed. Based on the forced vibration in the process, the cutter path is defined by the relative displacement between the tool and the workpiece, and the cutting force model of x and y directions are established. According to the experimental requirements, a flexible platform with two degrees of freedom is established. The frequency response function of the workpiece system and the cutting tool system is measured, and the proper rotation speed of the spindle is selected according to the stability chart.
