Contour Mode Deterministic Microgrinding aspe.net. of the program was the development of a contour mode aspheric grinder and deterministic microgrinding process thatrepeatably produces aspheric optical surfaces in glass or IR materials with less than 1.0 wave pv figure error, surface roughness of 100 Årms, and less than 1µm of subsurface ...
OSA | Contour Mode Deterministic Microgrinding
The development of next generation asphere manufacturing technology is being finalized at the Center for Optics Manufacturing (COM). The Nanotech™ 150AG aspheric grinder produces optical surfaces with less than 1.0 wave p-v figure error, surface roughness of 100 Å rms, and less than 1 pm of sub-surface damage. This stone discusses COM’s recent manufacturing technology advances and ...

Analysis of chatter in contour grinding of optical …
Chatter that limits ground surface finish has been observed in the deterministic microgrinding of brittle optical materials. In this article, the classical single degree of freedom model for chatter, accounting for both work and tool regenerative effects, is adapted for contour grinding optical surfaces. A linearized expression for the cutting stiffness is developed for the contour grinding ...

Microgrinding | 4m-association.org
Microgrinding is also applied to surface finish thermally sprayed hard coatings [8]. However, considerably high values of compressive biaxial subsurface stresses are generated, with a large gradient in the thickness direction. One of the technological problems is the fact that the tool must be made up of an abrasive and a matrix. When the tool size is very small, the stone size cannot be ...
