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，

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.
