【正文】 G Software. First in CAD modeling, draw the 3D model of chargers through tensile entities, Boolean operation, shell entities and entities rounding function. Then in UG processing module, plete the Chargers virtual manufacturing model. It produces two plane contour milling procedures. One is a rough machining procedure another is a precision machining procedure. In post processing, the topic selects the MILL_3_AXIS machine. It can produce procedure which can be identified by machine. In the virtual manufacturing, processing craft must be considered which contains the cutting tool, cutting specifications choice and so on. The article also gives a detailed briefing. In addition, this paper introduces a program transmission method. By CimcoEdit input software generated procedures into Siemens milling machine. It should be noted that the rough machining procedure is short, may directly transmitted into machine. But the precision work procedure is very long and it cannot be transmitted into the machine. It needs to be transmitted while processing. This is called CNC.
