  • Diamond turning method for high-precision metal mirror
    Patent number: 4561333
    Abstract: High-precision turning of a metal mirror is accomplished by causing a measuring beam to be reflected on a freshly turned area of the reflecting surface to be formed in a metal blank being turned to produce a metal mirror and, at the same time, causing reference beams to be reflected on areas turned prior to the aforementioned freshly turned area, measuring the positions of incidence of the resultant reflected beams on a position detection device thereby performing the Hartmann test on the aforementioned turned areas of the reflecting surface and, based on the results of the measurement, controlling the nose position of the cutting tool now being used in turning the reflecting surface.
