Abstract: In all ages, for all the kinds of manufacturing
technologies adopted by human, the processing tools are always located
outside the stock material processed, the material is processed from its
outer surface or outer layer and the final shaping-surface should be
progressively reached. Nowadays, however, people start trying to put the
tool inside the stock material and let the processing energy be directly
used for forming the new surface of the part. Such a novel shape forming
technology is called as “inner processes”, and all the traditional
processes can be categorized as “outer processes”. The development from
outer processes to Inner Processes brings human’s shape-forming
technology from 2-D surface into 3-D space, which greatly improves
shape-forming capability. Hence, this trend is noteworthy. The
understanding on inner processes and achievements in inner processes
research are introduced and the prosperity in the near future of the
technique are described.
Keywords: Fabrication technology Shape-forming Outer process
