Abstract
An apparatus is provided for lightening of thin, flexible and shaped workpieces by removal machining of material from surfaces thereof, on a machining unit having a worktable and a counterthrust member which rests against a part of the surface of the workpiece opposed to the one on which said tool must work from time to time. The worktable includes a support member of the workpiece to be machined, and gripping mechanism which supports the workpiece during its machining independently of the support mechanism. The counterthrust mechanism includes a board movable according to several axes and carrying a plurality of supporting elements. The supporting elements can be individually translated or in groups between a draw-in position and an extended position to define a supporting plane depending on the shape of the surface of the workpiece against which the counterthrust mechanism rests. A method is also provided for mapping the workpiece surface.
