Requirements analysis : gives the procedure of system analyzing, as well as the functional modeling, dynamic modeling and object modeling. 系统需求分析介绍了利用所选择方法进行期刊编辑管理系统的需求分析,建立系统功能模型、动态模型和对象模型的过程;
In this paper, the metallic functional part is rapidly manufactured by Laminated Object Manufacturing ( LOM ) process using the thicker sheet metal as the modeling materials. But the question of modeling precision in the LOM must be solved. 本文提出以较厚的金属板材作造型材料,采用分层实体制造方法快速制造金属功能零件,但必须解决LOM造型精度问题。
