A study on the electrolytic in-process dressing (ELID) for silica glass in a ductile mode

It is important to develop a new grinding technique with higher efficiency for hard and brittle materials. As a requirement of optical transmission, the electrolytic in-process dressing (ELID) is used to manufacture high quality silica glass with ultra-precision. This technology has many virtues, such as high efficiency and high precision. Atomic force microscope results have been used to optimize grinding parameters and achieve a ductile mode during the manufacturing process. With a low feed rate and an appropriate speed, silica glass surfaces with a good quality have been obtained.
