Due to the good corrosion behaviour and the high specific strength of titanium alloys, their ratio of the structural weight in modern aircraft developments reaches nearly 15 %. This is twice as much as in the last aircraft generations and leads to the applica-tion of large (>3 m) structural titanium parts like door frames, lintel and sill beams. For these structural parts open die forgings are milled. Hereby, over 95% of the raw material is removed. The quenching process after forging induces residual stress into the forgings. Releasing the stress by removing material can lead to strong part distor-tion, especially by long and slender parts. To ensure an economic and scrap free production of these large structural titanium components, a new adaptive clamping system for load-free clamping has been devel-oped to avoid a time-consuming manual adjustment before the finishing processes. In this paper the assembly of one adaptive clamping element and its experimental verifi-cation concerning distortion-free clamping is presented.
