High Speed Machining of Brittle Optical Material

Machinging Brittle Optical Material

Prof. Matt Davies recently demonstrated high speed machining of brittle optical material at 400 mm/min, 40,000 rpm, 100 micrometer step-over and 200 micrometer depth of cut. This translates to a material removal rate of 8 cubic millimeters per minute. Roughing parameters for milling are now comparable to that of turning in the same material.
