| 摘 要： | 以平面圆轨这上各点空间与几何的关系为基础，提出了一种测量三和何误差的新使用Ｒｅｎｉｓｈａｗ检查规测量ＸＹ，ＹＺ、ＸＺ平面内特定圆周上各点的空间误差，通过最小二乘法，可分同所有２１项几何误差，这种方法操作方便、精度高，仅用２ｈ即可完成全部２１项误差的测量，为通过补偿提高坐标测量机的精度提供了有效手段。

| Abstract: | Based on the relationship between volumetric errors and geometric errors of CMM,a new method of measuring the geometric errors is developed in this paper.Through the measurement of volumetric errors on some specific circles in XY,YZ,XZ planes with a Renishaw Checking Gauge all the 21 geometric errors can be obtained by means of the least square method.The new method is accurae and easy to use.The time required for data acquisition is less than two hours.It is an effective method to improve the CMM precision by error compensation. |
