摘　　要：为解决金属手机外壳加工行业内的机床主轴轴向热误差问题,提出了一种基于时间序列算法的主轴轴向热误差建模方法,对一台钻攻中心建立了主轴轴向热误差实时补偿模型。实践结果表明:通过该模型实时补偿,机床的主轴轴向热误差由原来62μm补偿到7μm,加工工件尺寸控制在10μm左右。To solve the problem of the axial thermal error of spindle in metal mobile phone shell processing industry,this paper proposes an thermal error modeling method based on the time series spindle axial. The spindle axial thermal error modeling is established on a bench drilling tapping center. The practice results show that the axial thermal error of machine tool spindle is compensated from 62 μm to 7 μm through the model real-time compensation,the size of part is controlled at about 10 μm.

关 键 词：时间序列 主轴轴向热误差 实时补偿
