数控管切割机三维仿真加工若干问题的研究

为解决检验数控管切割机加工工艺合理性的问题，基于OpenGL 和3DSMax 平台，并在OpenGL 中通过参数驱动导入的3DS 静态模型，实现了加工过程和结果的三维 动态演示。同时相对于传统的利用碰撞检测技术再现切割后管材的相贯线形状，提出了改进 的数学模型，新算法通过了快速性、准确性等的验证。

Research on some problems in 3D simulation of CNCpipe cutting machine processing

To test the justifiability of cutting pipe process with CNC machine, OpenGL and 3DSMax technologies are used to achieve the 3D dynamic presentation of process and cutting result by driving the imported 3D static model with the parameters in OpenGL environment. Compared with the traditional method which is based on collision detection to reproduce the shape of pipe intersection, a new mathematical model is presented, and it has been proved to be fast and accurate to calculate the intersection.
