Three-Axis Contouring With The Large Optical Generator

The Large Optical Generator (LOG) of the University of Arizona's Optical Sciences Center recently celebrated its second birthday.1,2 During these two years several projects have been completed with the LOG, the most important being the three molds for the Sub-Millimeter Telescope. The accuracies achieved with LOG are discussed as well as the work under way to shift machine operation to a three-axis mode of operation. The use of a toroidal cutting wheel is suggested for solving some problems presented by application of spherical wheels to upcoming work.
