OSTI ID:6787659
Single point diamond crushing of glass was originally developed by Dr. R.E. Reason of Taylor and Hobson in England 34 years ago as a means of shaping glass aspheres prior to polishing. It has recently been tried at LLNL. A surface finish of 50 microinches peak-to-valley with occasional deeper pits has been achieved on Zerodur and BK-7 glass. A depth of cut of 0.008 inch or more can be taken at a surface speed of 900 feet per minute. Tool wear is on the order of 10 microinches after removal of one cubic inch of Zerodur. The tool's cost is $5.45 each.
