Paper Abstract

An automated aspheric polishing machine has been constructed using a readily available microcomputer, off-the-shelf servomotors and controllers, and other commercially available mechanical components. A computer model of the polishing process was developed and used to investigate the effect of various tool shapes and motions on the polishing process and the shape of the material removal profile. Suitable tool shapes and motions were determined from the model. A microcomputer controlled aspheric polishing machine was designed to produce these motions. Software was developed to control the servomotors, monitor the process, calculate material removal profiles, and interface with the user. Examples of precision aspheric surfaces fabricated using this process are presented. Other possible uses and future developments are also discussed.
