| Abstract: | A mathematical model on the influence of three-dimensional locating upon machining accuracy is established. Matrix method is employed to calculate the locating error of a part. The locating errors of a machining part located in a fixture using 3 typical locating methods are presented. The locating error of a part located by the way of one plane-two pins is calculated as an example. The mathematical model can be employed to evaluate the machining accuracy for computer-aided fixture design. |
