摘要：

The inherent vibration in a precision diamond turning machine at the natural frequency of the slide cannot be compensated for by the slide drive. In order to provide in-process error correction a higher bandwidth actuator such as a tool servo proved to be an efficient way to prevent these vibrations of the machine from being transferred into the surface of diamond turned parts. This study investigates the sources of small amplitude vibration errors that are translated into the precision finished parts and proposes an efficient method of eliminating those types of errors. The error correction process includes real time monitoring and compensation of the disturbances that improves the final surface quality. This method could theoretically be useful in correcting less precise machines for use as precision finishing machines. © 1990.
