Optimal Design of Polishing Trace for Link-Type Optical Fiber Polisher

Abstract:

Mike Buzzetti proposes an optical fiber polisher which is a link-type mechanism with double flats in 1999. Buzzetti’s optical fiber polisher produce 8-shaped grinding traces to polish the end face of optical fiber connector. The purpose of this paper is to design the optimal polishing traces of single-plate optical fiber polisher to avoid the patent of Buzzetti’s mechanism. First, a link-type single-plate optical fiber polisher, which is consist 7 links and 8 joints, is proposed. Then, analyze the polishing trace, velocity, and acceleration of Buzzetti’s mechanism and new mechanism. Finally, we take the curvature scope percentage (_sp) and the velocity deviation percentage (V_dp) as the objective functions, and use global search to achieve optimized design so that the double- crank single-plate optical fiber polisher will produce the optimum polishing trace which is like the digit “8”. The results of this paper are: (1) The velocity deviation percentage of double-crank single-flat optical fiber polisher (V_dp= 61.8241%) is lower then the original mechanism (V_dp= 76.8652%). And, (2) The maximum acceleration of double-crank single-flat optical fiber polisher (a_max = 1231 cm/s²) is lower then the original mechanism (a_max= 2323.0 cm/sec²). The result indicates that the polishing effect of the double-crank single-flat optical fiber polisher is better then original mechanism.
