【摘要】 光栅刻划机被誉为“精密机械之王”,采用高精度的衍射光栅刻划机刻划依然是制作高质量母光栅最重要的手段 ,因此 ,对高精度的光电式光栅刻划机进行研究具有重要的现实意义。文中主要阐述了两类光电式刻划机的控制原理 ,并对其特点进行了比较更多还原

【Abstract】 A diffraction grating ruling engine is known of "the king of fine mechanics". It is still the most important means for the fabrication of master grating. Hence, it is valuable to study the high precision photoelectric ruling engine. The principles of two sorts of photoelectric ruling engines are described and the comparisons of the characteristics of them are given in this paper.更多还原
