| Abstract: | The linear relationship between the volume and size tolerance of upsetting piecesis derived.The origin of size tolerance and the transition relationship between the weight tol-erance and size tolerance are revealed. The algorithm and onedimensional linear regressionmethod for establishiy the practical size tolerance are also given. |
