| 针对管一管复杂管桁架结构中管端焊接装配面实际切割角易发生突变而影响正常装配这一问题，分析了其形成
原因以及对数控管切割机的影响。在易于加工且不影响焊接装配的前提下，运用多项式插值的方法，对实际切割角突变
弧段进行了优化，使管端焊接装配面平滑，易于加工。最后结合实例算法与仿真，通过分析其弧长一实际切割角曲线以及
对比优化前后焊接装配面实际切割角三维模型效果，验证了该优化算法的可靠性。为数控管件切割方式的改进提出了
一种新思路。 |
| 英文摘要: |
| As the actual cutting angle of the welding assembly surface of the complex truss structure prone changes
suddenly, its causes and effects on CNC pipe cutting machine have been analyzed. On the premise of easy processing
without influencing the welding assembling surface and by using the polynomial interpolation, the actual cutting angle
mutation arcs were optimized. So the welding assembling surface became smooth and easy to process. Finally, examples
of algorithms and simulation were made to verify the reliability of the optimization algorithm by comparing the three-
dimensional model before and after the optimization. It provides a new cutting method for the improvement of the
numerical control tube. |
