如何排除导轨的基准误差不被带入被测元素形状中,本文就根据误差分离技术的反向消隙法来试探分析其可行性。1.测量步骤(1)测量前准备首先将要被检测的平尺做好测量前准备,并按将要检测的采样点数等距标记在平尺两侧,将被测平尺放于直线度检测仪上(见图1),在平尺的长度方向的2/9处放等高垫铁支撑,移动测微 How to rule out the rail reference error is not included in the shape of the measured element, this article based on the error backlash anti-backlash method to test its feasibility. 1. Measurement steps (1) Preparation of measurement First of all, to be tested flat feet do a good job of measurement preparation, and according to the sampling points to be tested at equal distance markers on both sides of the flat feet, will be measured flat rulers placed in the straightness detector (See Figure 1), in the horizontal length of 2/9 at the same place put high horn support, moving micrometer
