| 摘 要： | 作为五轴数控机床的关键零部件,数控回转工作台能够实现C轴和A轴的回转进给与定位,其精度在很大程度上决定了数控机床的加工精度。以此为研究背景,建立了回转工作台的空间误差模型,对回转工作台的几何误差进行测量,并建立了误差补偿的数学模型,为最终进行机床的误差补偿提供依据,从而实现数控加工中心加工精度的提高。

| Abstract: | As one of the key components in five-axis CNC machine tool,rotary table enables the rotating feed and allocation between A and C axis,and precision of the machine tools is determined by that of the rotary table. Based on this research background,the volumetric error model of the rotary table of CNC mahine tools is established.The geometric error is measured,and the mathematical model of error compensation is presented, the basis for error compensation of machine tools is provided,in order to achieve the improvement of machining accuracy. |
