Abstract

We describe the project management procedure applied to the manufacture of 8.2 m Zerodur blanks. Such a complex, challenging task needs detailed organization from planning via implementation to realization. Some examples of inspection and handling procedures are presented in detail. The excellent performance of all four 8.2 m Zerodur blanks is demonstrated with some characteristic properties like geometrical dimensions, internal quality and coefficient of thermal expansion. The delivery of the fourth blank in 1996 represents the culmination of a decade long development and production project.
