The results that, as long as the appropriate parameters, using the above method not only can punch the square hole, can also be processed triangle, the five angle and hexagonal regular polygon holes. The square hole processing method can provide theoretical basis and engineering reliable reference for related engineering and technical personnel.展开更多
China went on an airplane-buying frenzy in 2005, and in the process made Boeing and Airbus happy with large orders for planes from both companies. During U.S. President George W. Bush's Beijing visit last November,
