In the aeronautic field, parts need many phases of machining and joining. The presentation proposes to apply analysis line method on manufacturing transfer. This method realizes both specification synthesis and tolerance analysis. The major contribution is a set of rules which make possible to calculate a three-dimensional transfer in the case of braze welding operations. For each functional requirement, the conditions are expressed as sets of linear relations on production deviations, from blank parts to finished part. These relations allow specification of blank parts, machining phases and braze welding phases. The method is applied on a part from Snecma.
