Abstract
An apparatus and method for machining of thin panels, in particular, panels having a complex shape, specifically non-deformable panels, in which the panel to be machined is placed beforehand in an isostatic position, characterized by: one defines one or more areas of a predetermined extent for purposes of machining, named machining windows, in the area of the panel to be machined; and perpendicular to each machining window; one of surfaces of panel is held in position without introducing positioning hyperstatism; the actual shape of the aforementioned surface is measured; the desired machining operation is performed on the opposite surface by taking the aforementioned measured surface as a reference; and the aforementioned surface is released.
Claims6
A device for positioning and machining a thin panel having a complex non-deformable shape, said device including:
- a means for isostatic positioning of the panel that is to be machined,
- a means for holding one of the surfaces of the panel in position over a predetermined extent, without introducing hyperstatism;
- a means for measuring an actual shape of said surface with regard to said holding means;
- a means for displacing said holding means with regard to said surface of the panel;
- a multi-axis means of machining located over to another surface of the panel;
- and
- means for synchronously controlling the successive displacement and location of said holding means with regard to each of one or more said machining windows, and said machining means successively perpendicular to each machining window.
