Abstract

Aiming at the characteristics of high brittleness, low fracture toughness and difficulty in processing of raw materials for aspheric optical components, a new method of creating optical aspheric surfaces based on two-dimensional ultrasonic elliptical vibration abrasive belt grinding was proposed. In this paper, a new path planning algorithm for machining optical aspheric surfaces by abrasive belt grinding was designed, which took into account the radius compensation of abrasive belt grinding head and the micro displacement of the machining path excited by the ultrasonic vibration in Y and Z directions. And a typical aspheric surface, toric surface, was used to simulate the machining path planning, which proved the effectiveness and correctness of the proposed machining path planning algorithm. This technology will play a positive role in promoting the development of precision machining technology with ultrasonic vibration for aspheric surfaces.
