| Abstract: | On the basis of the large scale investigation and accumulation of data ,the load and the number of cycles of CNC lathe are analyzed. The distribution model of load spectrum is built by means of multiple regression method. In order to make the model of load spectrum precise and reliable, the synthesis percentage of goodness of fit is employed to evaluate the goodness of fit. This provides a foundation for reliability design of CNC lathe. |

| Keywords: | CNC lathe load spectrum multiple regression synthesis percentage of goodness of fit least square method |
