摘　　要：以一台重型卧式车床为例,基于刚体运动学原理建立了机床几何误差模型,得到了各轴线几何误差源与加工误差之间的映射关系,而后采用激光干涉仪、水平仪等测量仪器获取了机床部分几何误差源的误差数据,并进而预估出机床全工作空间内的加工误差变化规律,可用于指导机床的误差补偿等工作,以提高机床的精度性能。This paper taking a heavy-duty horizontal lathe as an example,based on the principle of rigid body kinematics,established the geometric error model of the machine tool,obtained the mapping relationship between the geometric error source of each axis and machining error.Then,obtained the error data of some geometric error sources of the machine tool are by using laser interferometer,level instrument and other measuring instruments,and predicted the variation of the machining error in the whole working space of the machine tool.The datas can be used to guide the error compensation of machine tools,so as to improve the accuracy performance of machine tools.
