Precision grinding and facing of copper-beryllium alloys ...

Oct 01, 1999  Lack of a nanometric reference made it difficult to calibrate the measuring equipment. Although repeatability of a technique was well within 10%, a 500% difference was seen when measuring surface finish with either a contact-type profilometer, a semicontact-type SPM, or a noncontact-type PSI . The stylus of a profilometer left a visible scanning mark on the surface of a sample when viewed by
