Abstract: The author proposes the
principle of automatic shape generation by the manufacturing
process simulation. A combined geometric representation has been
founded for the realization of the principle in practice. The
algorithms of the interference-free offset and the 3D object
sweep have been invented to generate the CL data, the draft and
blending surfaces of the compound sculptured shapes. Based on
the new concept the author has developed an integrated CAD/CAM
system that is different from the conventional study. Some
examples are to show the successful applications in the
complicated die & mould.
