| Abstract: | The reliability of NC system of NC machine tool was very important to the quality of NC machine tool.For its data was little ,how to use a little data to forecast its future became very useful in theory and in practice.Grey System was a theory which studied poor information specially,and possessed wide suitability.Center approach optimum Grey GM(1,1) model was introduced.An example was given in NC system fault prediction of NC machine tool.So a high precision model for it and a good method were established.It can be widely used. |
