31、包括模具设计、制造、分析、产品演示、数据转换等等，使它成为具有实际应用解决方案的软件系统，但在工程中要实现应用需要其它模块的支持。MasterCAM美国NC Software公司所开发研制的CAD/CAM系统软件，由于卓越的加工功能，在世界上拥有众多的忠实用户，被泛应用于机械、航空、造船、模具等领域。然而MasterCAM的设计(CAD)功能相对薄弱，在进行复杂曲面造型时一比较困难，而这正是SolidWorks的优势所在。本文为MasterCAM软件提供了DXF , I(ES , CADL , VDA , STL, PA-RASLD , DWG等标准图形转换接口，可以把其他CAD软件生成的图形

32、转变成本系统的图形文件，实现图形文件共享。建立完模型后选择合理的加工方式，利用MasterCAM的车削、铣削和线切割模块能高效地编制各种数控加工程序，方便快捷地实现图形的雕刻功能。因此利用SolidWorks进行CAD设计，结合MasterCAM进行数控加工，就成为当前模具企业优先选择的CAD/CAM方式，下面以手机盖模具为例，介绍SolidWorks结合MasterCAM9. 0在模具设计和加工方面的应用。2基于SolidWorks的手机盖模具设计SolidWorks软件具有很强的建模功能，利用其拉伸、切除、钻孔、倒角、抽壳、曲线曲面等命令可以完成各种类型的零件设计。2. 1原始设计模型以手

33、机盖例，利用SolidWorks软件选择零件，先选择草图并绘制草图，进行尺寸约束和几何关系约束，然后进行拉伸、切除、钻孔、倒角等生成三维立体图。2. 2手机外壳制作加工(1) SolidWorks手机外壳制作如上面打开零件绘图框，选择“前视”，插入“基准面1，在“等距距离”框中输入“10，建立基准面1,如图1图1基准面建立在“前视面”上绘制椭圆图形，选择“工具/草图” 绘制“工具/裁剪”直线对椭圆进行裁剪、尺寸设置，如图2。在“基准面 1”上绘制同样图形，选择“插入/凸台基体/放样”，弹出放样对话框，在“轮廓”框中分别选择“草图1”和“草图2，选取图形上表面的边线对其倒圆角，半径为10 mm，

34、如图3选择“工具/草图绘制实体/文字”在图形上表面绘制文字，然后点击“拉伸凸台/基体”按钮，深度1mm，效果如图4( 2 ) Mastercam手机外壳模拟加工打开Mastercam操作界面，点击File/Converters/IGES/Read file，找到所存文件并打开，即可完成Solidworks与Mastercam图形文件的转换，如图5所示。 然后经过不同步骤的加工部位选取、刀具选择、刀具参数设置(图6) ,加工路径设置、粗加工参数设置、精加工参数设置等设置，最终完成手机壳的数控自动编程)选取图不边线并按图进行设置。完成上述各种工艺参数设置，经过下述加工步骤仿真(图7最终成型如图8

PST文件则MasterCAM9. 0将生成适合该机床运行的数控程序。MasterCAM软件系统针对许多数控系统开发了与之匹配的后处理文件(如FANUC , SIEMENS ,MITSUBISHI等)，选取相应后处理文件，即可直接生成特定数控系统所需的数控加工程序。由于此系统是国产的南京华兴21M数控系统，MasterCAM软件系统中没有与之相匹配的后处理文件，自动生成的NC程序不能直接传送给数控机床进行加

36、工，需要进行简单的修改。修改完毕即可将文件传输给数控机床，完成工件的加工。对自动生成的数控程序主要进行了以下三方面的修改。删去程序开头、段尾一些对于系统没必要的说明解释性的程序代码，在程序中间换用刀具的说明也应删除。 例如: % 00000 (PROGRAM NAME一BB1) (DATE=DD一MM一YY一06一05 TIME=HH:MM一10;45) N0 G21 N2 GO G17 G40 G49 G80 G90 (16. FLAT ENDMILL TOOL.一1 DIA.OFF.一1. LEN. 一1DIA. 一4）删去木系统没有定义的指令代码。例如: N4T1 M6删去M6; N6G

37、0G90X一70. Y一90. A0. S5OOM3删去AO替换程序中与本系统表示方式不同的程序代码(如格式、符号等)，使系统能够正确识别程序，获取理想的加工零件 例如: N8 G43 H1 Z50改作N8 G42G01 Z50 ; N1922M30改作N 1922 M023结语介绍了SolidWorks软件和MasterCAM 9. 0软件的功能模块和工作流程。以手机外壳教学模型为例详细介绍了SolidWorks软件和MasterCAM 9. 0软件的一些基木操作，包括CAD零件的几何造型,CAM零件的模拟仿真加工、NC代码的后处理过程三部分。此外，还介绍了SolidWorks软件与MasterCAM软件图形文件的转换。将其智能化的3D绘图功能和MasterCAM软件具有的图形文件转换接口功能紧密结合起来，实现优化设计。将SolidWorks软件的CAD优势和MasterCAM软件的CAM优势有机结合，可以大大缩短用户精确设计与加工凸轮的时间。参考文献1门超，张宝树.基于pro/engineer与MasterCAM的模具CAD/CAM铸造技术，2007(4);519一5222陆荣明. 基于pro/engineer与MasterCAM的模具设计与加工CAD/CAM与制造业信息化，2006(9)107一108
