| Abstract: | Machine manufacturing accuracy is an important norm to evaluate product quality. To improve the quality of a machined product, the dynamic distributions of machining errors related to the process of the product manufacturing procedures and its variation characteristics must be well understood. There exits a lot of factors influencing manufacturing accuracy, some of them are known, however, there are still some ones unknown. So a machine manufacturing process is a typical gray process. This paper established a mathematical model for the dynamic distributions of dimension errors in bearing grinding process by means of the gray systematic theory. On the basis of the model, the dynamic distributions of machining errors at present and in the future were analyzed and predicted. The research results showed that the model had a high accuracy and the predicted values from the model were well agreed with the measured data. |
