Abstract:
Plastic lenses are very fragile and scratch easily. Therefore, to remove the plastic lens from the door without causing any damage, a precise base bracket is required. This article describes a method for separating plastic lenses using a 15 KHz ultrasonic horn. In this case, EDM and servo motors are used to make micro on the base holder by adjusting the gap voltage, pulse on time, pulse off-time, and outlet water pressure. To check longitudinal vibration at 15 KHz frequencies for ultrasonic horns, perform harmonic analysis by providing 15KHz frequency as the input value. The experimental results demonstrated that the average error of machining micro-holes is 0.01025 mm by EDM. The ultrasonic horn is designed to fit with 15 KHz, after tuning the ultrasonic vibration, the total machining time is 1.25 seconds, and all the plastic lenses on the workpiece gate can break within one cycle. The quality accuracy of the plastic lens is 90.83%.
