The traditional grinding machine can not be used to polish optical fiber ferrules. In the early day, planetary polisher was proposed for polishing the optical fiber ferrule. However, this conventional planetary grinding device just can only polish one optical fiber ferrule at one time. 2008, Hsieh proposed a planetary polisher for polishing many optical fiber ferrules at the same time. Based on the research of Hsieh et al., the complete planetary optical fiber polisher is proposed, in which three position pins (A, B and C) are sitting on the three planet gears and grinding disk is positioned by these three position pins. Hence, the three points of A, B and C have the same donut traces, all points on the grinding disk will have the same donut polishing traces and have same polishing qualities. According to kinematic equations, we derive the equations of polishing trace and velocity of planetary optical fiber polisher. Then, based on the polishing velocity, velocity deviation percentage (V_(dp)) is calculated, which is an important design parameter. Area ratio (A_R) is defined as polishing area divided by grinding pad area. The area ratio (A_R) is another important design parameter for designing planetary optical fiber polishers. For the fixed value of AR (for example A_R =88.36%), according to design constraints and requirements, the optical fiber polisher with suitable velocity deviation percentage (V_(dp)) is synthesized. This paper provides an application experience in the design of planetary optical fiber polishers.
