Abstract:
1. A method of machining a thin wall structure, comprising the steps of: a) fixedly mounting the thin wall structure on a first fixture of a machining tool, b) positioning a dam member in spaced-apart facing relationship with a first surface of the thin wall structure opposite to a second surface thereof to be machined, the dam member and the first surface of the thin wall structure defining a gap extending over substantially the entire area to be machined, the thin wall structure being fixedly held on the first fixture independently of the dam member; c) substantially filling said gap with a meltable material, once set, the meltable material providing a backing to said second surface to be machined, d performing a first machining operation on the second surface of the thin wall structure, and e) separating the thin wall structure from the meltable material.
