Study on the Turing of Toric Spectacle Lens by Use of Slow Tool Servo Method

Abstract:

To solve the difficulties in machining toric spectacle lens, the turning method with slow tool servo was discussed. First, the experimental setup was developed, which have X-axis, Z-axis and C-axis, and the movement of the three axes can be simultaneously controlled by numerical control system. Then, the mathematical model of toric was established, and its machining model was analyzed and simulated. Finally, the machining experiments were carried in the experimental setup. The experiments showed that the turning method based on slow tool servo can meet the requirements for machining the toric spectacle lens.
