The purpose of this NASA Technical Handbook is to cover recommended material removal processes (i.e., machining or grinding) for advanced ceramics and glasses, which are referred to as "ceramics" in this NASA Technical Handbook. It is applicable to both test specimens and components, hereafter referred to as "specimens." This NASA Technical Handbook is not intended to replace or supersede customary (e.g., internally accepted or proprietary) or application-matched machining/grinding practices. Instead, it is intended to provide recommended material removal procedures developed from experience and testing, and thereby ensure consistent test specimen and component performance. Geometries addressed in this NASA Technical Handbook include prismatic sections, flat plates (disks and square plates), and cylindrical rods. Grinding parameters, including diamond (abrasive)-grit size and material removal rates, are addressed in addition to cutting fluid type and conditions. Appendix A, Recommended Polishing Specifications for Ceramic Windows, provides a specific application example. NASA Endorsed. OCE.
