| 摘 要： | 利用高精密步距规对坐标测量机运动误差的分析进行了研究,建立了误差分离的数学模型,通过将步距规按一定规则在空间内摆放并进行测量,可以得出坐标测量机的定位误差、角摆误差、直线度误差和垂直度误差.该方法也可以应用在数控机床、加工中心等领域的误差分析.

| Abstract: | A method of geometric error correction in coordinate measurement ( CMM ) with step gauge is presented. The step gauge is placed in different positions. According to the relation of volumetric error and geometric error, the mathematical model of straightness error is built. The geometric error such as position, pitch, straightness, squareness can be obtained. This method also can be used for error analysis of linear motion guide. |
