  • Mirror grinding Hacker News

    2017-03-10  The center of the mirror is the most likely to be contacted by any motion, so it is abraded more frequently and becomes the deepest point, while the edges are worn less. The distribution between "less" and "more" is spherical. I can at least understand the process of grinding or lapping a surface flat. Here are a couple examples:

  • Study on a 5-axis precision and mirror grinding of glass ...

    The precision freeform grinding depends on the on-machine truing of diamond wheel, leading to the inefficiency of grinding system. Hence, a virtual ball-end algorithm along with a fixed tool posture angle is proposed for the 5-axis grinding of glass by using a self-dressing diamond wheel.
