A method of processing a workpiece with a first surface and a second surface facing away therefrom includes the following principal steps: (i) blocking the workpiece with the aid of a blocking material on a blocking member with the blocking material between blocking member and first surface, (ii) processing the workpiece by a geometrically defined cutting edge at the second surface for achieving the desired macrogeometry, (iii) processing the workpiece by a geometrically undefined cutting edge at the second surface for achieving the desired microgeometry and (iv) deblocking the workpiece from the blocking member. The principal step (ii) includes a plunge-cutting sub-step (ii.2) in which by a geometrically defined cutting edge an encircling plunge cut is produced which extends through the first surface as far as into the blocking material so that the workpiece with a predetermined edge profile remains on the blocking member radially within the plunge cut.

A method of removing a metal sleeve from a bore formed in one or more elements is disclosed. The sleeve may be a cold-expanded sleeve secured within the bore by an interference fit. The method includes removing material from the internal surface of the sleeve by a cutter along a line to a depth less than the thickness of the sleeve, and subsequently urging the sleeve from the bore.

Systems and methods are provided for assembling a structure. The systems and method including micro pulsing a structure along a track in a process direction by less than a length of the structure. The structure is indexed to one or more work stations by mating indexing features in a manufacturing excess of the structure to complementary features at the work stations. The work stations would the perform work on the structure at the work stations while the structure is indexed to the work stations. Iteratively repeating the micro pulsing and indexing and working upon the structure until it is ready to advance to the next assembly process.
