| Abstract: | The sources and causes of major errors in ultra-precision CNC machine tool are described according to the basic demands of ultra-precision machining. The effects of nonlinear factors in feed system on the dynamic performance, static performance and machining accuracy are analyzed as well. This paper reviews the current research status of nonlinear control strategies in feed system and total error compensation methods, together with the research achievements of this period. As to the future research fields and some key issues, the authors make some prospects. Finally, it is proposed that accuracy of this kind should be improved by combining advanced controlling technology with total error compensation technology. |
