Modeling of tool shape evolution in conformal (raster)

CNC grinding relies on accurate control of the tool shape and position relative to the workpiece. However, tool wear can significantly alter tool shape, potentially producing figure errors. This problem can be particularly important in conformal grinding applications which require the grinding of large areas to optical tolerances and/or the use In the limit of small abrasive size (ductile-mode grinding), the maximum surface compressive stress achieved is near the yield stress of the glass, in agreement with finite-element simulations of indentation in elastic-plastic solids. and deterministic microgrinding experiments (at a fixed infeed rate) conducted at the Center for OpticsTwyman effect mechanics in grinding and microgrinding.

Chatter simulation and stability predictions for contour

Chatter marks from 0.1 µm to 2 µm in depth have been observed on glass surfaces that have been deterministically microground in the contouring mode. A model for regenerative chatter during the contour grinding of optical glasses is developed and will be used to identify process parameter combinations that decrease the likelihood of chatter. Abstract. We report a series of microgrinding and polishing experiments on glass–ceramics. Microgrinding includes deterministic microgrinding (two-body abrasion at fixed infeed rate) and looseDeterministic Microgrinding, Lapping, and Polishing of
