Thermal Error Modeling and Compensation for an INDEX-G200 Turning Center

摘要：

The purpose of this research is to fulfill thermal error modeling and compensation of an INDEX-G200 turning center. This paper presents the whole process of thermal error modeling and compensation by using back propagation neural networks. Results show that the BP model improves the prediction accuracy of thermal errors on the turning center and the thermal drift has been reduced from 39 μm to 11 μm after compensation.
