Ultra Precision Machining.

Abstract

Our work focuses on various aspects of ultra-precision manufacturing. The development of optical sensing techniques initially applied to the non-straightness of ways and the application of shear interferometry in measuring this characteristic machine tool imperfection. In actuation we have been principally interested in hydraulics. The ability of the working fluid to carry away the heat of inefficiency provides promise for improved thermal performance in actuation. Hydraulics, however, have historically operated in flow regimes which introduced vibrations and seismic disturbances. So we have worked primarily on quiet hydraulics. Out of this some work on spindle metrology, vibration isolation evaluation, and some inovative techniques for machine tool operation have developed in addition to the actuation along the ways that were the initial thrust. Finally, the control environment for machines working at ultra high precision involves many considerations besides the immediate feedback control of axis motion. Imbedding this mixture of requirements in a computational environment provides a number of opportunities to improve the accessability and the friendliness of information to the operator. These areas are summarized below in this order with sensing, actuation, and computational environment as their subheadings.
