Research of Displacement Self-Apperceive Micro-Feed Tool Carrier Based on GMM

The Micro-feed tool carrier drived by GMM has lots of merits such as large feed force, high displacement resolution, wide displacement range and connected with machine tool rapidly, it surmounts the shortcoming of the PZT driver such as PZT's excursion of the PZT's terrace structure and the intricate PZT's avoiding creepage structure for the PZT working in high voltage situation, when the magnetic field changed, nano-metric displacement output is realized by the Micro-feed tool carrier, for the function of Micro-displacement self-apperceiving of the Micro-feed tool carrier, it is easy to realize the Micro-displacement automatic compensating, the application foreground for the Micro-feed tool carrier drived by GMM used in the field of Super-precision manufacturing is extensive.
