<p>The present invention relates to a method for working a piece with a machine called a parallel-architecture machine of the type comprising a movable tool-holder table connected to a fixed table by a plurality of legs, the machine being programmed to carry out theoretical cycles of the tools, characterized in that: the fixed table (4) of the machine (1) is fixed relative to a zone of the piece to be worked; measurements are taken of the relative position between a first entity specific to the machine and a second entity specific to the piece; from the measurements previously acquired, the exact position is deduced, in coordinates and in inclination, of the first entity in a frame of reference; the preprogrammed theoretical cycles of the tool or tools are modified according to the exact relative position of the two entities calculated in the previous step.</p> |
