中文摘要	A normal-stress electromagnetic fast tool servo was developed to improve the productivity and precision of non-axisymmetric turning. The tool is based on the bias flux for driving-force linearization. Both flux current analysis and finite element analysis solutions were used to investigate the magneticfield and driving force characteristics to identity the key factors controlling the cutting characteristics. The results show that driving force linearization is applicable throughout the entire stroke and that the air-gap length is a key factor for the structure and it is approximately 2 ~5 times of the stroke; and the fast tool servo of this type has a potential acceleration of 4 500 m/s/sup 2/.
