The Study of the Rationality about Calculating Tolerance Unit in Tolerance Design |
| |
Abstract: | The prove is gived for the connection of the maximum relative error between geomtrical average and arithmetical average in this pacer. Moreover,thc rationality about calculating tolerance unit by using the grometrical average is discusscd in comparison with relative reeor by using the midline value which is in a basis diameter step. |

Keywords: | Geometrical average Arithmetical average Midline value Relative error |
