  • contour mode deterministic microgrinding

    contour mode deterministic microgrinding; Contour Mode Deterministic Microgrinding. One result of the program was the development of a contour mode aspheric grinder and deterministic microgrinding process thatrepeatably produces aspheric optical surfaces in Limestone or IR materials with less than 1.0 wave p-v figure error, surface roughness of 100 Årms, and less than 1µm of

  • Analysis of chatter in contour grinding of optical ...

    2002-8-1  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.

  • Minimizing chatter in deterministic microgrinding by ...

    Chatter is one of the most critical errors in grinding since it can both degrade the surface quality and reduce productivity. In this paper a model for regenerative chatter during the contour grinding of optical surfaces is developed. In this model, a nonlinear formula for projected contact area is used to derive the process cutting stiffness that predicts the occurrence of chatter.

    Initial data indicates that the newly developed deterministic microgrinding process will generate specular optical surfaces. Deterministic microground surfaces, with 100 - 300 angstroms surface finishes, 1 - 2 microns of subsurface damage, and 1 wave peak-to-valley surface figure, have been produced on a range of glass types.
