多管相贯坡口曲线等离子切割的割炬姿态控制算法

为了实现多管相贯焊接坡口的高效和高质量等离子切割,建立了多管相贯线的数学模型,给出了多管相贯焊接坡口数控切割的割炬姿态控制函数,提出了基于等离子切割特性的割炬姿态控制函数的离散算法,并用该算法对焊接坡口割炬姿态控制函数进行了离散,给出了离散结果,用MATLAB对切割速度的变化情况进行了仿真,最后根据该姿态控制算法进行了焊接坡口的切割试验.结果表明,该算法能根据切割厚度的变化对割炬姿态进行有效离散,实现了对切割速度的基于等离子切割特性的精确控制,可以有效的提高焊接坡口的切割质量.

Control algorithm of torch posture for plasma cutting of welding groove along multi-pipe intersecting ed

In order to ensure the proper cutting and improve the cutting efficiency of welding groove along multi-pipe intersecting as well,by setting up a mathematic mode on the multi-pipe consistency,It is then puts forward the control algorithm of torch posture for NC cutting of welding groove along multi-pope intersecting edge.The discrete algorithm of torch posture on the basis of plasma cutting characteristics was put forward,which discreted the control algorithm of welding groove along multi-pope intersecting,the result of discretion was also given.The change of cutting speed was stimulated with MATLAB,and finally the experiment of cutting was carried out based on the control algorithm of the posture.Theoretical analysis and simulation result showed that the algorithms could disporse the torch posture efficiently based on the cutting thickness,achieve the precise control of cutting speed based on the characteristics of plasma cutting,hence,it could improve cutting quality effectively.
