Euler’s equation grinding track, microgrinding mechanism, and process research of space optical crystal materials

Abstract: In microdiameter precision grinding of the YAG (Y₃Al₅O₁₂) optical crystal material, centerless precision grinding is the necessary process of the preparation method to obtain surface finish. To further obtain the optical crystal devices in optical field, the tiny diameter of the optical crystal material is the key element. However, the process to generate the grinding ratio of the grinding a_p forms part of precise control of the actual mathematical calculation for the ceramic base grinding wheel. In this work, we propose a satisfying precision grinding models for engineering applications and a theory to explain the grinding process of the microdiameter YAG optical crystal materials. A ceramic base of the grinding wheel axis is designed, and the wheel axis experimental parameters are regulated from controllable clearance and eccentricity for the e by the grinding depth and surface finish quality. The resultant parameters keep constant during the precision grinding and self-adaption dressing process to avoid the deviation caused by centrifugal force. In the process of self-adaption dressing of ceramic base grinding, wheel rotation direction is controlled by critical parameters such as the grinding wheel axis (-), and the regulating wheel axis (-) is the critical parameters to determine the final appearance of the grinding wheel. The value range of the feed location region is [0.022, 1.007]. Grinding wheel axis speed and regulating wheel axis speed are 35~60 RPM. Thus, the process challenges and technical issues of YAG optical crystal material microdiameter precision grinding can be solved. Graphical Abstract: [Figure not available: see fulltext.]
