| Abstract: | Based on Multi-body System Theory, a comprehensive error modeling method for five-axis machine center is presented here To verify its validity, a simulation was carried out to show the obvious improvement of CNC's machining accuracy once compensation process is performed, and the necessity to eliminate the thermal error in machining complex surface of high accuracy requirement |
| Keywords: | five-axis NC machine multi-body system theory thermal error software compensation parameters' identification |
