| Abstract: | The measurement principle of rotary accuracy of hydrostatic rotary table using laser interference method is introduced,and main factors and inducements of errors of the laser interferometer in measuring the precision of rotational axis are analyzed.A curve of sine approximate error in angle measure is devised,a mathematical model of the measurement error is presented.Thus it provides data for the motion precision machine error compensation.This program was simple and effective through the field test verification. |
