摘要
A strategy for machining ceramic (silicon carbide) mirrors is described. By taking advantage of the relative ductility of ceramics compared with that of glass, ft is shown that fixed-abrasive, ultraprecision grinding is a viable fabrication process for high-performance aspheric mirrors. Also, it is shown that ductile grinding of ceramic substrates can produce optical quality surfaces, particularly in infrared applications. Laboratory-scale ductile-regime grinding of chemically vapor deposited silicon carbide is described, as is a scale-up of the technology to a commercially available ultraprecision machine tool that has been retrofitted for grinding aspheric ceramic components.
