A method of machining an attachment flange of an aircraft turbomachine case, the method also including a system to machine the two opposite surfaces of the flange, and including a shape follower machining module, this module being designed to follow the shape of the flange and including a first structure equipped with a first machining tool, and a second structure equipped with a second machining tool, the flange fitting between the structures such that its two opposite surfaces are machined by tools, the module also including shape follower elements carried by the structures; and a device to drive movement of the machining module along a circumferential direction of the flange.

A machining device, including: a cart, for carrying a master-piece and a work-piece; a rail, for allowing manual sliding of the cart along the rail thereabove; a first vice for securing the master-piece, the first vice being fixed to the movable cart; a second vice for securing the work-piece, the second vice being fixed to the movable cart; a limiting element, for limiting the manual sliding of the cart upon meeting of the master-piece with the limiting element; and a protrusion including at least two points extending downwards from the rail; thereby the machining device utilizes parallelism between the channel and a cutting blade of the table saw.
