Abstract：The net assembly technology is presented in the process of composites component of aircraft. Error accumulation
is reduced and coordination accuracy is improved with digital quantity transfer in the process of product design
and manufacturing. In order to improve the assembly accuracy, the measuring device, such as laser tracker is applied, the
assembly accuracy and tolerance distribution is adopted with the stage of assembly process design. Taking an composites
component as the typical research structure of composites fuselage, the process flows and methods of net assembly technology
is defined. The method can realize one time clamping, processing and without repeated assembly of the parts, so that
the assembly quality has good stablility.
