Abstract: A technology of two-coordinate dual-servo (TCDS) is proposed. Using
this technology which is based on error compensation, workpieces
of higher contour accuracy could be turned on ultra-precision
machine tool with poor dynamic performances. The principle,
constitute and operation of a TCDS system are described.
Mathematical proof and experiments are achieved in addition.
Key words: Ultra-precision
manufacturing Dual-servo Contour error
