Study Of Numerical-Control Turning Machine Automatic Programming System

NC programming system has played an important role in the integrated CAD/CAPP/CAM system.It forms a crucial link between products design and manufacturing.A reliable intelligentized NC programming systerm is one of premise condition of how to realize CAD/CAPP/CAM integration system.Based on conclusion and absorption of some advance of existing NC automatic propramming systems, aimed at the mormal characteres of NC truning machine programming,the thesis is intended to introduce a new method of NC turning machine programming桸C automatic programming system based on feature modeling. Based on AutoCAD 2000,utilize ObjectARX 2000 & Visual C++ 6. 0 to develop a NC automatic propramming systems integrated in AutoCAD 2000. The works of this thesis are as follows. First, found revolving part feature modele, according to this feature modeling system, utilize ObjectARX 2000> Visual C++ 6. 0 to get and deal with part parameters from AutoCAD 2000, at last found CAD Production Model In CIMS. Second , according to this feature modeling system & revolving part aided process parameters to produce NC program, deduce machining track from this program to realize numerical control turning simulation. In this way it will convenience mechanical stylist mostly,and realize genuine CAM(Computer Aided Manufacture).
