基于CAD/CAM的零件三维造型与数控加工

Part's 3D Modeling and CNC Machining Based on CAD/CAM

以Pro/E和MasterCAM软件为平台进行零件的三维造型和数控加工。根据两者各自的优越性,利用Pro/E软件对零件进行快速造型,并导入到MasterCAM软件中进行数控加工,生成刀具路径。结合零件的结构特征,分析了MasterCAM软件中各种精加工刀路的特点,探讨了该零件的加工方法,并制定出合理的加工方案,保证了加工品质,提高了加工效率。

The Pro/E and MasterCAM softwares are used as a platform to carry out the 3D modeling and the CNC processing for a part.As campared with the advantages of tow kinds of softwares above,the fast modeling to the part is carried out with Pro/E,and the part is imported into MasterCAM to carry out the CNC machining and generate the tool path.In combination with their structural features,each kind of finish machining tool path＇s characteristic is analyzed with MasterCAM.Its processing method is discussed,and the reasonable processing program is developed.The processing quality is guaranteed and the processing efficiency is raised.
