Aiming at the existed deficiency of integrated application of digital technologies, the integration scheme of digital design/manufacturing/management in aeroplane process equipments is proposed. Its collective technologies and practical research items are analyzed, together with existed CAX systems and their data transfer relationship with MES/PDM. The united information model and knowledge reuse technologies are studied to ensure the successful product development. Based on the above researches, an integrated application system is set up, which is composed of seven sub-systems, like management of process equipments orders etc. Therefore, “paperless” manufacturing in the Hafei Aviation Company has finally come true.
