Abstract

Opticians and machinists employ opposing techniques to achieve precision in their work. The optician relies on a subtle biasing of repeated loosely controlled tool motions and statistical averaging to produce polished surfaces with relatively simple geometrical configurations and extremely small surface errors. The machinist, on the other hand, relies on precisely controlled tool motions to produce complex shapes in a single pass. If we are to succeed in single-point turning optics we must design and build machine tools capable of controlling spindle and tool motions to optical tolerances. We will discuss machine tools for single-point turning of aspheric optical surfaces in terms of overall design philosophy, choice of materials, alternate approaches to the implementation, monitoring and control of tool and spindle motions. We will demonstrate, with numerical examples, the magnitude of the problems associated with the construction of these machines.
