【摘要】：为了研究综合考虑机床主轴运动误差、刀柄与弹簧夹头安装误差等因素的切削仿真,将机床主轴的角接触轴承、刀柄、弹簧夹头的安装与制造误差作为影响铣削刀具轴线运动的主要因素,建立了铣削刀具轴线的运动数学模型。将SPN 300型主轴动态误差分析仪金属标准球的运动轨迹作为反映铣削刀具轴线的运动轨迹,对模型进行了实验验证。考虑到粒子群算法对不同复杂约束条件下的多目标优化问题具有较强的适用性与简便性,使用粒子群算法标定模型中的未知参数。实验结果显示,所建立模型与实际测量结果相符,且所提标定方法具有较强适应性。
[Abstract]:In order to study the cutting simulation of machine tool spindle motion error, tool handle and spring chuck installation error, angle contact bearing and tool handle of machine tool spindle are studied. The installation and manufacture error of spring chuck is the main factor that affects the movement of milling tool axis. The mathematical model of the milling tool axis is established. The movement track of the metal standard ball of the SPN 300 spindle dynamic error analyzer is used to reflect the movement track of the milling tool axis. The model is verified by experiments. Considering the applicability and simplicity of particle swarm optimization algorithm for multi-objective optimization problems with different complex constraints, the unknown parameters in the model are calibrated using particle swarm optimization algorithm. The experimental results show that, The model is in agreement with the actual measurement results, and the proposed calibration method has strong adaptability.
