【Abstract】 On the basis of analyzing and calculating the normal unit vector of NURBS surface,NC preliminary design paradigm is put forward.By exploiting typical modules:like translating module、rotating module and Base module,the NC movement conceptual configuration has been expressed precisely.This conceptual module was recorded in the form of List in computer.By the introduction of “agent”,creative preliminary design was realized in this article.更多还原
