METHOD FOR IN SITU MACHINING OF A LARGE DIMENSION PART WITH A PARALLEL ARCHITECTURE MACHINE

摘要

The invention relates to a method for machining a large dimension part with a so-called parallel architecture machine, of the type including a mobile tool-carrier plate connected to a fixed plate by a plurality of tabs, the machine being programmed for performing theoretical strokes of the tools, characterised in that it comprises: attaching the fixed plate (4) of the machine (1) relative to an area of the part to be machined; measuring the relative position between a first entity related to the machine and a second entity related to the part; deriving from the previously acquired measures the exact position in terms of coordinates and inclination of the first entity in a universal set; modifying the pre-programmed theoretical strokes of the tool(s) based on the exact relative positioning of the two entities calculated during the preceding step.
