| Abstract: | The effect of machining accuracy caused by thermal error of NC machine tool and the key factors which lead to thermal error are analyzed.The thermal error of NC machine tool predicted by neural network is lucubrated in this paper.A dynamic feedback neural network model is presented.The establishment of this model,some key technical problems in this system are discussed.Finally,the model was tested by a set of experimental data.The results testify it is efficient that this model predicts and compensates NC machine tool thermal error. |
