基于逐次二点法三坐标测量机直线度运动误差的测量

摘要

分析了逐次二点法在三坐标测量机直线度运动误差测量方面的可行性,介绍了逐次二点法的测量原理,并定量分析了传感器及安装引起的误差.对现有的三坐标测量机进行测量,结果表明,采用逐次二点法对直线度运动误差测量实用可靠,可以满足测量的要求.%The feasibility of measurement of straightness motion error for CMM based on Sequential Two Points Method was researched, the principle of measurement of Sequential Two Points Method was introduced and errors from the misalignment and adjustment sensors were analyzed quantificationally. According to the straightness motion error for existing CMM, the results indicated that the method of Sequential Two Points to measure straightness motion error, which can content with the requirements of the measurement accaracy,is practical and reliable.
