  Material removal and surface generation mechanisms in …

  202418 · High-efficiency precision grinding can shorten the machining cycle of aspheric optical elements by a factor of 2–10. To achieve this objective, ultrasonic vibration (UV)–assisted grinding (UVG) has been increasingly applied to manufacture aspheric optics. However, the mechanisms of material removal and surface formation in UV-assisted …

  Study on Precision Grinding of Micro Aspherical Surface ...

  Authors have successfully developed the 45 degrees tilted grinding method, and ultra-precision micro aspherical shape has been obtained. The improvement of the form accuracy will be required because the specifications of micro lenses become more and more strict in future. However, the shape correction cannot be done satisfactorily, because the ...
