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 paper discusses COM’s recent manufacturing technology advances and ...

2002-8-1 In this article, a model for chatter occurring during contour deterministic microgrinding is developed based on classic chatter theory. Experimental methods developed to measure factors that affect the grinding process stability, including the machine frequency response function (FRF) and the Preston coefficient, are described.

2011-4-22 Deterministic microgrinding (two-body abrasion) causes lower SSD values than other grinding methods that use similarly sized abrasives (for example, loose abrasive or three-body abrasion). Finally, it is possible to estimate the range of SSD from the average abrasive size in terms of an upper and lower bound.

2019-6-18 The process of machining hard and brittle materials in such a mode is called ductile-regime machining. When the undeformed chip thickness is larger than t c, however, cracks are generated, forming fractured cutting chips. These two different machining regimes are schematically shown in figure 2 . The brittle-ductile transition is originated ...
