Abstract
本发明属于精度补偿加工技术领域，具体为一种机床热变形实时监测的动态精度补偿加工方法，包括采集工况状态数据与多点温度监测数据，预测基准热误差并确定当前机床热变形稳定状态。依据热变形稳定状态设定误差补偿刷新频率机制，结合加工环境数据进行调整，得到补偿频率自适应调整机制。分析动态耦合误差分析数据对基准热误差进行修正，得到最终动态热补偿量。根据补偿频率自适应调整机制对各类数据进行补偿执行轨迹控制优化，生成动态补偿加工指令以控制机床执行加工，同时依据轴向工况三维坐标索引方法构建热误差状态索引表，对全流程数据进行关联存储；本发明能显著提升整体补偿精度，改善系统利用资源率，保障机床运行稳定性。
