National Aeronautics and Space Administration (NASA). This Technical Handbook approved by NASA 12-03-2013. Superseding NASA-NDBK-6007. 22 p. The purpose of this Handbook is to cover recommended material removal processes (i.e., machining or grinding) for advanced ceramics. It is applicable to both test specimens and components, hereafter referred to as specimens. This 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.
