文摘

In the aeronautic field, parts go through many phases of machining and joining before completion. We propose to apply analysis line method to manufacturing transfer. This method enables both the analysis and the synthesis of production specifications. The major contribution is a set of rules which facilitates the calculation of a three-dimensional transfer in the case of braze welding operations. The resulting transfer relations are linear inequations in terms of the manufacturing tolerances, from blank parts to finished part. These relations enable the specification of blank parts, machining phases and braze welding phases. The method is applied to a part from Snecma.
