| Abstract: | Compensation and control of errors is an important method to improve precision of NC machine tool. As precondition, the error modeling and analysis are important too. The basic information, origin, modeling and parameter identification of geometric error, thermal error, error of cutting force and control error were expatiated. Study status for errors was summarized, and capable study for the future was brought forward. Control strategy of reducing error and software compensation of comprehensive error were discussed, reasonable method for improving precision of machine tools was put forward. |
