工艺预研是国防预研的重要组成部分,具有和其它专业预研的共性,即研究内容广,综合性、探索性强,难度高、风险大,协作面、应用面广。更有其特殊性,即工艺预研是其它专业预研的基础,且物化性强。三院在建院三十多年来,随着一系列型号的研制和生产,工艺技术有了较大的进步,“七五”期间,在上级主管部门的大力支持下,开展了海防导弹CAM技术、精密铸造技术、超塑成型扩散连接技术、焊接新工艺 Craft pre-research is an important part of national defense pre-research, and has the same common features as other professional pre-research, ie, it has a wide range of research contents, comprehensiveness, exploratory nature, high difficulty, high risk, collaboration, and wide application. More specific, that is, the pre-research of the process is the basis for other professional pre-research, and it has strong physics and chemistry. In the 30th year since the establishment of the Third Hospital, with the development and production of a series of models, the process technology has made great progress. During the “7th Five-Year Plan” period, with the strong support of the superior authorities, the Hainan Defense Missile CAM was launched. Technology, precision casting technology, superplastic forming diffusion connection technology, welding new technology
