Research on IGES Graphic Input and Display Technology Based on Feature Information

Abstract:

In order to input graphics of NC machining parts efficiently, now take the turning IGES rotary parts graphic input for example, it introduced the manual input and methods of obtaining the feature information of the parts generated from UG5.0 IGES file. The feature information contains geometry information (such as line, arc, spline curve, etc) and process information (such as size tolerance, form tolerance, technical conditions and the title bar, etc). In VC++6.0, it set up three modules, that’s the IGES file information input, data processing and data output. Feature extraction and input were realized by using intersection algorithm of graphic elements. Through data processing module, the read pixel information could be transformed into the feature information of the parts, generating the system data structure. OpenGL technologies were used to realize the IGES graphics display, finally offering supports for NC turning visualization of virtual machining.
