| Abstract: | Based on multi-body system theory,for a precision machining center with table station,the space synthesis error model was established.The error transfer problems resulted in movement error of the exchangeable table to synthesis error were analyzed and solved,and the synthesis error modeling method of thermal drift error of each axis was improved.The machining precision of machining center can be effectively improved by using of the error model for real-time compensation. |
