| Abstract: | The model of the failure probability distribution was obtained by applying total failure time method for the numerical control punch. Through the graphic and analytic method, its model of fitting was verified qualitatively and quantitatively. The optimum distribution model was determined as Weibull distribution, providing a theoretical basis for the failure analysis and prediction, and reliability enhancement of the numerical control machine tools. |

| Keywords: | numerical control punch total failure time method failure probability distribution model |
