例句与用法

1. Machining center ' s geometric accuracy is the key to guarantee the processing accuracy of machine tool . the testing of geometric accuracy is the base of testing machining center ' s straightness accuracy
   加工中心几何精度是确保机床加工精度的关键，其中直线运动精度的检测是几何精度检测的基础。
2. In new state standard < < machining center testing items - accuracy testing > > [ refering to iso / dis10791 ] , issued in 1999 , the test of straightness accuracy has been changed . now it becomes more scientific and reasonable . in old state standard , the testing of straightness accuracy of kinetic part only focus on vertical and " horizontal plane , and it only includes two linear errors ; but in new state standard , we not only measure those two linear errors , but also measure the errors of pitching , deflecting , and inclining of the kinetic part , so it includes two linear errors and three angle errors
   1999年公布的国标《加工中心检验条件?精度检验》 (参照iso dis10791订)中，直线度等项的检测做了更为科学的实质性更改，坐标移动的直线度以由只检测垂直面和水平面内的两个平移线值误差，改为用移动坐标方向之外的另两个坐标的平移线值误差和移动部件绕三个坐标轴的俯仰，偏摆和倾斜三个角值误差综合表征。
