Design and Implementation of Tube Bending CAD/CAM System
管道弯制CAD/CAM系统的设计与实现

The related problems in tube bending process and the frames of the tube bending CAD/CAM system were presented,and a divided scheme of the system modules was given out.Conversion algorithms from XYZ coordinate to YBC coordinate were constructed.In consideration of the springback and elongation characteristics of a tube,a compensation algorithm was designed so as to compensate the manufacturing data of tubes and obtain accurate cutting stock size.Based on process conditions and collision factors,the bendability of a tube was analyzed from two hierarchies which were rude analysis and simulation analysis.The system was implemented in Visual C++ programming tool and OpenGL graphics library,now it is running successfully.
