Abstract In this paper, the source of target precision and influencing factors of aircraft assembly tooling are analyzed in detail. The design method of target precision is described. The influencing factors are quantitatively analyzed, and the influencing importance is qualitatively analyzed. As for each influencing factor, the corresponding treatment measure is given. The possibility of eliminating each influencing factor under corresponding treatment measures is analyzed and case studies are conducted. The qualitative and quantitative analysis of the tooling target precision is proposed theoretically and applied to design of assembly tooling for a certain aircraft, in which a preliminary path is explored for the unified and quantitative accuracy analysis of assembly tooling in engineering. The analysis of relevant influencing factors of target accuracy provides a basis for target accuracy design in assembly tooling design stage and cause analysis in fault stage.
