轴类零件CAD/CAPP/CAM一体化连接数据库设计与实现

Design and Realization of Database Used to ConnectCAD/CAPP/CAM of Shaft Parts

通过建立ＩＧＥＳ转换接口，利用ＡＵＴＯＣＡＤ输出的ＩＧＥＳ标准格式文件建立数据库并用分层特征描述法对零件几何及工艺信息进行描述，设计人机交互接口数据库这两种方式，实现了回转类零件的ＣＡＤ／ＣＡＰＰ／ＣＡＭ一体化连接。

T,wo methods for establish database are introducedi the first one is to establish IGES eschange interfbce and then to establish dlatabase by using IGES standard formatting files which come from AUTOCAD; the second one is to describe part geometry and process planning information by gradation feature methnd, and to estahlish database by using mantmachine interfacet The connection of CADJCAPP/CAM for shaft parts can be realized using above methods.
