WEDM ( Wire -Cut Electrical Discharge Machining WEDM ) is a special processing , usually used to cut the more complicated parts of the profile curve , such as : mold forming tool , have high requirements on the machining accuracy . With the rapid development of computer technology , WEDM programmatically from simple interactive graphical programming development to today's CAD / CAM / CAPP integration technology to achieve automatic programming . Automatic programming from the current level of technology at home and abroad , are usually adopted for existing CAD system , secondary development , expansion of CAPP and CAM functions of the CAD system to achieve , such as Pro / Engineer , MasterCam , CATIA , Cimatron , but these systems are expensive . Therefore , in general CAD system platform developed automatic programming system to make it have the CAPP, CAM function , is a major pathway of some special programming system . This article using the AutoCAD2000 the development tools ObjectARX2000 and Visual C 6.0 AutoCAD platform developed WEDM automatic programming software . The main findings are: . Graphics Interchange save graphics data file in AutoCAD DXF (Drawing eXcharge File) file structure extracted WEDM Part graphical data processing required , and according to the requirements of the process on these data processing , mainly including the reordering of geometric entities diameter compensation , according to its diameter compensation amount WEDM machining direction . Graphical data processing information in accordance with the code of the processing procedures format automatically compile WEDM two G- code and 3B format processing program . 3 . Development of the processing track preview function, can test the correctness of the part program . Developed a special curve automatic drawing and automatic programming function , can be quickly and accurately draw special parts for WEDM graphics and automatic programming . Based on the above work , the development of automatic programming software based on AutoCAD platform EDM wire cutting , and it has the the basic EDM wire cutting programming .
