Abstract:
It’s very important for missile radome to be precisely machined,
especially for the inner surface of it. The performance of the radome
and even the missile will be greatly affected by its making quality. How
to realize the reconstruction of the radome surface from a large numbers
of discrete data of it, is the key for the precise machining. The
reconstruction of 3D surface for the radome, base on the method of
bicubic B-spline surface, is presented, and from which the
computer-aided drawing can be carried out. Furthermore, equation of
offset surface from the reconstruction would make easy planning for
cutting tool path in NC machining of the radome.
