Aiming at the high precision machining for weak rigid parts of aircraft

the digital measure technologies including collaborative calibration for robot milling system

edge extracting and reverse modeling of skins

and positioning correction of end-effector were developed. Based on the above measure of edge machining allowance and on-line correction of machining process

the measurement error of skin edge was 0.1mm and end-effector positioning error was no more than 0.2mm for skin

cover and panel of aircraft. The digital collaborative measure in this paper meets the requirements of digital measurement for advanced aircraft manufacture

improves level of automatization and digitization for skin and panel milling of aircraft

and accelerates the progress from handwork assembly to intelligent assembly.
