Abstract

A method for correcting extrinsic loading effects on kinematic accuracy of a machining assembly (20) includes determining, for a positioning system (32) of the machining assembly (20) including a cantilevered arm (44) and a rotary table (34) mounted on the cantilevered arm (44), a first position and a first orientation of a first axis (54) and a second position and a second orientation of a second axis (56), filling a machining tank (46) with a dielectric fluid, determining a third position and a third orientation of the first axis (54) and a fourth position and a fourth orientation of the second axis (56), and determining position and orientation correction factors for the first axis (54) and the second axis (56) using a position and orientation deviation of the first axis (54) and the second axis (56) in the first condition from the first axis (54) and the second axis (56) in the second condition.
