Error compensation for pentagonal prism
-
摘要: 由于五角棱镜两B棱的投影夹角对第二光学平行差影响倍率较大且加工过程中无法测量该夹角，从而导致棱镜加工合格率较低。通过分析侧面垂直度误差及45对五角棱镜光学平行差的影响，提出一种新的五角棱镜加工工艺方法：利用最后一个加工面对前3个已加工面存在的角度误差进行一次性补偿，从而降低了对各加工面的加工误差要求。实践证明：该方法能够有效地提高五角棱镜加工的合格率和生产效率，减小加工难度，并能显著降低对加工和检测设备的精度要求。Abstract: The projection angle of two B-edges of pentagonal prism has a great effect on the second optical parallelism; however, it cannot be measured during on line processing, which results in low qualification rate. By analyzing the impact of perpendicular error of the side face and angle error of 45 on the optical parallelism of pentagonal prism, this paper provides a new process for producing pentagonal prism, which modified the angle error of the last face to compensate the angle errors of three processed faces so as to release the strict requirements for process error of these surfaces. By using this process, qualification rate and productivity was raised, the complexity of the process was reduced, and the strict requirements for the machine and measurement equipments were released.
