Research and Application of CAD/CAM Technology in NC Machining of Part with Complex Surface

Abstract:

The development of modern advanced manufacturing technology greatly relies on the CAD / CAM technology. Many pieces of computer software with CAD/CAM function have been developed rapidly in recent years. Unigraphics (UG) is one of the outstanding representatives. It has a powerful design and CNC programming function, and CAD/CAM seamless connectivity. As an application example, a mouse model part which has complex surface was designed and trial-manufactured with CNC machine. First, the 3D model of the part was created in the modeling module of UG software. Then, the process scheme was developed after analyzing. In the manufacturing module of UG software, the NC machining parameters were set according to the processing requirements, the tool paths were generated, edited and checked, and the NC codes were generated by post processing. And then, the NC machining was simulated in YULONG software. Finally, the part was manufactured in a 3-axis CNC milling machine. It has desirable shape and high accuracy. The results show that UG has a perfect CAD/CAM function. The CAD/CAM technology based on UG makes the NC machining of complex surface part very convenient. It improves the efficiency of design and machining, shortens the manufacturing cycle, and reduces the cost, which reflects the importance of the CAD/CAM software in NC machining. The method described in this paper can provide valuable reference for processing similar parts, and it is also useful for related study.
