Paper Abstract

In this paper the equations that describe off-axis conic surfaces for a four axis approach to non-axisymmetric surface generation are derived. In addition considerations that minimize the fourth axis range of motion are reviewed. An example using a well known segmented astronomical mirror is used to illustrate these considerations.
